Płaskonabłonkowy rak skóry – Zapobieganie i profilaktyka

Płaskonabłonkowy rak skóry
Zapobieganie i profilaktyka

Rak płaskonabłonkowy skóry (SCC) stanowi około 20% wszystkich nowotworów skóry i jest drugim najczęściej występującym rakiem skóry po raku podstawnokomórkowym. Głównym czynnikiem ryzyka jest skumulowana ekspozycja na promieniowanie ultrafioletowe (UV), szczególnie u osób o jasnym fototypie skóry. Profilaktyka pierwotna opiera się na ograniczeniu ekspozycji na UV poprzez unikanie słońca w godzinach 10:00-16:00, stosowanie kremów z filtrem o SPF ≥30 z szerokim spektrum ochrony UVA i UVB, noszenie odzieży ochronnej z UPF 50+ oraz całkowite unikanie solariów, które zwiększają ryzyko SCC 2,5-krotnie. Profilaktyka wtórna obejmuje regularne samobadanie skóry co miesiąc oraz badania dermatologiczne co 6-12 miesięcy, zwłaszcza u pacjentów z wysokim ryzykiem, takich jak biorcy przeszczepów (ryzyko SCC wzrasta 65-krotnie) czy osoby z historią raka skóry. Leczenie zmian przedrakowych, takich jak rogowacenie słoneczne, obejmuje krioterapię, terapię fotodynamiczną oraz miejscowe stosowanie 5-fluorouracylu (5-FU), który redukuje ryzyko konieczności zabiegu chirurgicznego o 75% w ciągu roku.

Wprowadzenie do profilaktyki raka płaskonabłonkowego skóry

Rak płaskonabłonkowy skóry (SCC – Squamous Cell Carcinoma) jest drugim najczęściej występującym nowotworem skóry po raku podstawnokomórkowym, stanowiącym około 20% wszystkich nowotworów skóry. Jego częstość występowania wzrasta na całym świecie. W Stanach Zjednoczonych szacuje się, że ponad 700 000 osób było leczonych z powodu raka płaskonabłonkowego skóry w 2012 roku. Diagnostyka i leczenie tego nowotworu nakłada znaczne obciążenie na systemy opieki zdrowotnej, co podkreśla potrzebę skutecznych strategii profilaktyki pierwotnej i wtórnej.¹²

Najważniejszym czynnikiem ryzyka rozwoju raka płaskonabłonkowego skóry jest skumulowana ekspozycja na promieniowanie ultrafioletowe, zarówno zawodowa, jak i rekreacyjna, szczególnie u osób o jaśniejszym fototypie skóry. Dodatkowe czynniki ryzyka obejmują predyspozycje genetyczne, wiek, ekspozycję na inne czynniki środowiskowe (np. arsen, promieniowanie jonizujące) oraz immunosupresję.¹

Profilaktyka pierwotna: Ochrona przed promieniowaniem UV

Profilaktyka pierwotna ma na celu zmniejszenie ekspozycji na znane czynniki ryzyka poprzez stosowanie interwencji behawioralnych i środowiskowych, takich jak ograniczenie ekspozycji na promieniowanie ultrafioletowe.¹ Ponieważ rak płaskonabłonkowy skóry jest spowodowany ekspozycją na promieniowanie słoneczne, kluczowym elementem profilaktyki jest ochrona przed promieniowaniem UV.

Unikanie światła słonecznego w godzinach szczytu

Jedną z najskuteczniejszych metod ograniczania ekspozycji na promieniowanie UV jest unikanie słońca w godzinach, gdy jego promienie są najsilniejsze, czyli między godziną 10:00 a 16:00.¹² To właśnie w tym przedziale czasowym promieniowanie ultrafioletowe jest najbardziej intensywne, nawet w pochmurne dni i w okresie zimowym. Planowanie aktywności na świeżym powietrzu poza tymi godzinami znacząco zmniejsza ryzyko rozwoju raka płaskonabłonkowego.³

Gdy przebywanie na słońcu w tych godzinach jest nieuniknione, należy szukać cienia. Samo pozostawanie w cieniu jest jednym z najlepszych sposobów na ograniczenie ekspozycji na promieniowanie UV.¹ Dobrą zasadą jest „Brak cienia – szukaj cienia!” – jeśli twój cień jest krótszy od ciebie, szkodliwe promienie słoneczne są najsilniejsze i istnieje duże prawdopodobieństwo, że ulegniesz poparzeniu słonecznemu.²

Stosowanie kremów z filtrem przeciwsłonecznym

Regularne stosowanie kremów z filtrem przeciwsłonecznym jest jednym z podstawowych elementów profilaktyki raka płaskonabłonkowego skóry. Badania kliniczne wykazały, że codzienne stosowanie kremu z filtrem przeciwsłonecznym może zmniejszyć ryzyko rozwoju rogowacenia słonecznego (które może przekształcić się w raka płaskonabłonkowego) oraz samego raka płaskonabłonkowego.¹²

Zalecenia dotyczące stosowania kremów z filtrem przeciwsłonecznym:

Używaj kremu z szerokim spektrum działania (chroniącego przed promieniowaniem UVA i UVB) o współczynniku ochrony przeciwsłonecznej (SPF) co najmniej 30.¹²
Stosuj krem z filtrem przez cały rok, nawet w pochmurne dni i zimą.¹²
Nakładaj krem obficie około 30 minut przed wyjściem na zewnątrz.¹
Nakładaj ponownie co 2 godziny lub częściej, jeśli pływasz lub się pocisz.¹²
Nakładaj dużą ilość kremu na wszystkie odsłonięte obszary ciała, w tym uszy i stopy.¹
Stosuj krem wodoodporny, zwłaszcza podczas pływania lub intensywnego pocenia się.¹
Nakładaj grubą warstwę – około 2 łyżki na twarz i ciało.¹

Warto podkreślić, że regularne stosowanie kremu z filtrem przeciwsłonecznym wykazało się długotrwałym działaniem zapobiegawczym wobec raka płaskonabłonkowego skóry.¹

Noszenie odzieży ochronnej

Odzież stanowi prostą i skuteczną barierę ochronną przed promieniowaniem UVA i UVB. Zaleca się noszenie:¹²

Koszul z długim rękawem, spodni lub długich spódnic¹²
Kapeluszy z szerokim rondem, które chronią twarz, uszy i kark¹²
Okularów przeciwsłonecznych blokujących oba rodzaje promieniowania UV (UVA i UVB)¹²
Odzieży z ochroną przeciwsłoneczną oznaczoną współczynnikiem UPF (Ultraviolet Protection Factor), najlepiej o wartości 50+, co blokuje 98% promieni słonecznych.¹²

Należy preferować ciemne, ściśle tkane materiały, które zapewniają lepszą ochronę przed promieniowaniem UV.¹

Unikanie solariów i lamp opalających

Solaria emitują szkodliwe promieniowanie UV, które może prowadzić do długotrwałych uszkodzeń skóry i przyczyniać się do rozwoju raka skóry. Większość dermatologów i organizacji zdrowotnych zaleca niestosowanie łóżek i lamp opalających.¹

Badania wykazały, że korzystanie z urządzeń opalających może zwiększyć ryzyko raka płaskonabłonkowego 2,5-krotnie, a raka podstawnokomórkowego 1,5-krotnie, nawet po uwzględnieniu historii ekspozycji na słońce.¹ Spędzenie zaledwie 15-20 minut w solarium jest tak niebezpieczne jak dzień spędzony na słońcu.¹

Profilaktyka wtórna i wczesne wykrywanie

Profilaktyka wtórna obejmuje wczesne wykrywanie i leczenie raka skóry oraz zmian prekursorowych.¹ Regularne badania skóry mogą pomóc w wykryciu nowych zmian lub nieprawidłowych obszarów i pokazaniu ich lekarzowi, zanim będą miały szansę przekształcić się w raka skóry.¹

Samobadanie skóry

Regularne przeprowadzanie samobadania skóry jest ważnym elementem wczesnego wykrywania raka płaskonabłonkowego i innych nowotworów skóry.¹ Zaleca się następujące postępowanie:

Sprawdzaj swoją skórę raz w miesiącu, szukając nowych zmian lub zmian w istniejących znamionach, piegach, guzach i znamionach wrodzonych.¹²
Używaj lusterek do sprawdzania twarzy, szyi, uszu i skóry głowy.¹
Sprawdzaj klatkę piersiową, tułów oraz górne i dolne powierzchnie ramion i dłoni.¹
Sprawdzaj przednią i tylną część nóg oraz stopy.¹
Sprawdzaj podeszwy stóp i przestrzenie między palcami.¹
Sprawdzaj również okolice narządów płciowych i między pośladkami.¹
Zwracaj szczególną uwagę na guzy podobne do wyprysków, które nie goją się po trzech tygodniach, oraz zmiany przypominające wysypkę, które nawracają.¹

Regularne badania dermatologiczne

Oprócz samobadania ważne są również regularne wizyty u dermatologa w celu profesjonalnej oceny skóry.¹ Częstotliwość badań dermatologicznych zależy od indywidualnego ryzyka:

Amerykańskie Towarzystwo Onkologiczne zaleca badanie skóry związane z rakiem co trzy lata u pacjentów w wieku 20-40 lat i corocznie u pacjentów powyżej 40 roku życia.¹
Dla większości osób zaleca się coroczne badania skóry. Jeśli w wywiadzie występują liczne lub wysokiego ryzyka nowotwory skóry, zaleca się badania co 6 miesięcy.¹²
Po zakończeniu leczenia raka płaskonabłonkowego ważne jest przestrzeganie wszystkich wizyt kontrolnych, ponieważ istnieje ryzyko nawrotu raka oraz rozwoju nowego raka płaskonabłonkowego.¹

Dodatkowe strategie profilaktyczne

Chemioprofilaktyka

Chemioprofilaktyka to stosowanie leków, witamin lub innych środków w celu zmniejszenia ryzyka rozwoju raka.¹ Jest to strategia profilaktyki wtórnej dla pacjentów z wysokim ryzykiem rozwoju licznych raków płaskonabłonkowych (np. pacjentów z historią raka płaskonabłonkowego, rozległymi uszkodzeniami skóry wywołanymi przez słońce i rogowaceniem słonecznym, pacjentów z obniżoną odpornością).¹

Dostępne opcje chemioprofilaktyki obejmują:

Nikotynamid (witamina B3) – przyjmowanie nikotynamidu w dawce 1000 mg dziennie zmniejsza rozwój przyszłych raków płaskonabłonkowych i podstawnokomórkowych o 23 procent.¹²
Retinoidy doustne (acytretyna lub izotretynoina) – mogą być przepisywane pacjentom z wieloma rakami płaskonabłonkowymi. Zmniejszają liczbę guzów, ale mają pewne uciążliwe działania niepożądane.¹
Fluorouracyl miejscowy (5-FU) – w badaniu klinicznym wykazano, że stosowanie kremu z 5-FU przez okres do 4 tygodni zapobiegało rozwojowi nowych ognisk rogowacenia słonecznego.¹ Badanie wykazało również 75% redukcję ryzyka konieczności przeprowadzenia zabiegu chirurgicznego w celu leczenia raka płaskonabłonkowego w ciągu roku po zastosowaniu tego kremu.¹²
Kalcypotriol plus 5-fluorouracyl – jest to skuteczna immunoterapia przeciwko rogowaceniu słonecznemu. Krótki, 4-dniowy kurs leczenia kalcypotriolem plus 5-FU na twarzy i skórze głowy wiąże się z indukcją silnej odpowiedzi immunologicznej limfocytów T i znacznie zmniejsza ryzyko rozwoju raka płaskonabłonkowego w ciągu 3 lat od leczenia.¹

W przypadku preparatu Regencorr, który jest kremem stymulującym układ odpornościowy, stosowany jest jako profilaktyka w obszarach skóry narażonych na rozwój raka płaskonabłonkowego, w tym na małych bliznach powiek i nosa.¹

Leczenie zmian przedrakowych

Rogowacenie słoneczne (actinic keratosis) to zmiany przedrakowe, które mogą przekształcić się w raka płaskonabłonkowego. Leczenie tych zmian może zmniejszyć ryzyko rozwoju raka płaskonabłonkowego.¹ Opcje leczenia obejmują:

Krioterapię (zamrażanie) pojedynczych ognisk rogowacenia słonecznego¹
Kremy na receptę¹
Terapię fotodynamiczną¹
Leczenie laserem frakcyjnym większych obszarów¹

Unikanie innych czynników ryzyka

Oprócz ekspozycji na promieniowanie UV, istnieją inne czynniki ryzyka, których należy unikać:

Palenie tytoniu – palenie zostało powiązane ze zwiększonym ryzykiem raka płaskonabłonkowego skóry, jak również wielu innych typów raka.¹²
Narażenie na chemikalia – ekspozycja na pewne chemikalia, takie jak arsen, może zwiększyć ryzyko raka skóry. Przy pracy z chemikaliami należy zawsze nosić środki ochrony osobistej.¹²

Grupy wysokiego ryzyka wymagające szczególnej profilaktyki

Niektóre osoby są szczególnie narażone na rozwój raka płaskonabłonkowego skóry i wymagają specjalnych środków profilaktycznych.

Osoby z jasnym fototypem skóry

Osoby o jasnym fototypie skóry, z jasnymi włosami i oczami, piegami lub te, które łatwo ulegają poparzeniom słonecznym, są szczególnie podatne na rozwój raka skóry.¹ Te cechy fenotypowe są wyraźnie związane ze zwiększonym ryzykiem raka płaskonabłonkowego.¹

Pacjenci po przeszczepach organów

Biorcy przeszczepów narządów przyjmujący leki immunosupresyjne mają podwyższone ryzyko rozwoju raka skóry, szczególnie raka płaskonabłonkowego.¹ Ryzyko raka płaskonabłonkowego jest 65-krotnie większe u biorców przeszczepów w porównaniu z populacją ogólną.¹

Osoby po przeszczepach powinny zwracać szczególną uwagę na środki zapobiegawcze i badania kontrolne. Powinny ściśle współpracować ze swoim zespołem medycznym w celu zarządzania ryzykiem i zapewnienia regularnej oceny skóry.¹

Osoby z historią raka skóry

Osoby, które w przeszłości miały raka skóry, są bardziej narażone na ponowne zachorowanie.¹ Kanadyjski Program Opieki Opartej na Dowodach identyfikuje osoby z historią raka skóry jako mające bardzo wysokie ryzyko (tzn. 10 lub więcej razy większe niż populacja ogólna).¹

Pacjenci z historią raka płaskonabłonkowego skóry powinni praktykować skrupulatną ochronę przed słońcem.¹

Zalecenia dotyczące badań przesiewowych

Nie ma jednolitych zaleceń dotyczących badań przesiewowych w kierunku raka skóry. Różne organizacje i eksperci mają różne stanowiska:

Amerykańska Grupa Zadaniowa ds. Usług Prewencyjnych (U.S. Preventive Services Task Force) uznaje, że istnieją niewystarczające dowody, aby zalecać rutynowe badania przesiewowe w kierunku raka skóry za pomocą całościowego badania skóry. Zaleca jednak, aby lekarze pozostawali czujni na zmiany skórne o cechach złośliwych podczas badań fizykalnych wykonywanych z innych powodów.¹
Amerykańskie Towarzystwo Onkologiczne zaleca badanie związane z rakiem, w tym badanie skóry, co trzy lata u pacjentów w wieku 20-40 lat i corocznie u pacjentów powyżej 40 roku życia. Zaleca również, aby pacjenci przeprowadzali samobadanie skóry co miesiąc.¹

Wszyscy eksperci zgadzają się jednak, że ważne jest, aby znać własną skórę i kontaktować się z lekarzem w przypadku zauważenia czegokolwiek nietypowego.¹

Dodatkowe zalecenia dietetyczne i styl życia

Istnieją pewne dowody na to, że dieta bogata w zielone warzywa liściaste może zmniejszyć ryzyko raka płaskonabłonkowego skóry.¹ Jedno badanie wykazało również niższe wskaźniki zachorowalności na raka płaskonabłonkowego u osób regularnie przyjmujących niesteroidowe leki przeciwzapalne, takie jak aspiryna.¹

Nikotynamid, który można znaleźć w rybach, drobiu, jajach, roślinach strączkowych, orzechach i zbożach, może zmniejszyć częstość występowania nieczerniakowych nowotworów skóry, takich jak rak płaskonabłonkowy. Dostępna jest również rozpuszczalna w wodzie suplementacja w postaci niacyny lub witaminy B3, którą można kupić bez recepty.¹

Podsumowanie zaleceń profilaktycznych

Profilaktyka raka płaskonabłonkowego skóry opiera się na kompleksowym podejściu obejmującym:

Ograniczenie ekspozycji na promieniowanie UV poprzez unikanie słońca w godzinach szczytu, noszenie odzieży ochronnej i stosowanie kremów z filtrem przeciwsłonecznym.¹²
Całkowite unikanie solariów i lamp opalających.¹²
Regularne samobadanie skóry i profesjonalne badania dermatologiczne.¹²
Rozważenie chemioprofilaktyki dla osób z wysokim ryzykiem.¹²
Leczenie zmian przedrakowych.¹
Unikanie innych czynników ryzyka, takich jak palenie tytoniu i narażenie na chemikalia.¹²

Choć nie można całkowicie wyeliminować ryzyka rozwoju raka płaskonabłonkowego skóry, stosowanie tych środków zapobiegawczych może znacząco je obniżyć. Wczesne wykrycie i leczenie zapewniają najlepsze wyniki, a przy odpowiedniej profilaktyce i wczesnej interwencji wskaźnik wyleczalności raka płaskonabłonkowego skóry przekracza 95%.¹

#1 Cutaneous squamous cell carcinoma: Primary and secondary prevention – UpToDate
https://www.uptodate.com/contents/cutaneous-squamous-cell-carcinoma-primary-and-secondary-prevention
Cutaneous squamous cell carcinoma (cSCC) is the second most common nonmelanoma (keratinocyte) cancer after basal cell carcinoma, accounting for approximately 20 percent of all skin cancers. Its incidence is increasing worldwide; in the United States, it has been estimated that over 700,000 persons were treated for cSCC in 2012. As the diagnosis and treatment of keratinocyte carcinomas imposes a high burden on health care systems, there is a need for effective primary and secondary prevention strategies. […] Cumulative ultraviolet radiation exposure, either occupational or recreational, is the single most important risk factor for cSCC, especially in populations with lighter skin pigmentation. Additional risk factors include genetic predisposition, age, other environmental exposures (eg, arsenic, ionizing radiations), and immunosuppression.
#1 Cutaneous squamous cell carcinoma: Primary and secondary prevention – UpToDate
https://www.uptodate.com/contents/cutaneous-squamous-cell-carcinoma-primary-and-secondary-prevention
Primary prevention is aimed at reducing the exposure to known risk factors by using behavioral and environmental interventions, such as decreasing ultraviolet light exposure or arsenic contamination of water. Secondary prevention involves early detection and treatment of skin cancer and precursor lesions. Chemoprevention is a secondary prevention strategy for patients at high risk of developing multiple cSCCs (eg, patients with a history of cSCC, extensive sun-induced skin damage and actinic keratosis, immunosuppressed patients). […] This topic will review primary and secondary prevention strategies for cSCC. The prevention and management of skin cancer in organ transplant recipients is discussed separately. The risk factors, diagnosis, and management of cSCC are also discussed separately.
#1 Squamous cell carcinoma of the skin – Symptoms and causes – Mayo Clinic
https://www.mayoclinic.org/diseases-conditions/squamous-cell-carcinoma/symptoms-causes/syc-20352480
Most squamous cell carcinomas of the skin can be prevented. To protect yourself: […] Stay out of the sun during the middle of the day. For much of North America, the sun’s rays are strongest between about 10 a.m. and 3 p.m. Plan outdoor activities at other times of the day, even during winter or when the sky is cloudy. When outside, stay in shade as much as possible. […] Wear sunscreen year-round. Use a broad-spectrum sunscreen with an SPF of at least 30, even on cloudy days. Apply sunscreen generously. Apply again every two hours, or more often if you’re swimming or sweating. […] Wear protective clothing. Wear dark, tightly woven clothes that cover arms and legs. Wear a wide-brimmed hat that shades your face and ears. Don’t forget sunglasses. Look for those that block both types of UV radiation, UVA and UVB rays.
#1 Basal and Squamous Cell Skin Cancer Prevention | Skin Cancer Prevention | American Cancer Society
https://www.cancer.org/cancer/types/basal-and-squamous-cell-skin-cancer/causes-risks-prevention/prevention.html
There is no sure way to prevent all basal and squamous cell skin cancers. Some risk factors such as your age, sex, race, and family history cant be controlled. But there are things you can do that could lower your risk of getting these and other skin cancers. […] The most important way to lower your risk of basal and squamous cell skin cancers is to limit your exposure to UV rays. Practice sun safety when you are outdoors. […] Simply staying in the shade is one of the best ways to limit your UV exposure. […] Just like UV rays from the sun, the UV rays of tanning beds are harmful. Tanning lamps give off UV rays, which can cause long-term skin damage and can contribute to skin cancer. Most skin doctors and health organizations recommend not using tanning beds and sun lamps. […] Children tend to spend more time outdoors and can burn more easily, so they need special attention to protect their skin. Parents and other caregivers should protect children from excess sun exposure by using the steps above.
#1 Cutaneous Squamous Cell Carcinoma Treatment & Management: Approach Considerations, Electrodessication and Curettage, Surgical Excision
https://emedicine.medscape.com/article/1965430-treatment
Prevention is an important aspect of managing cSCC. Given the central role that ultraviolet radiation (UVR) plays in the pathogenesis of cSCC, methods aimed at decreasing UVR exposure form the cornerstone of cSCC prevention. […] Reduction of UVR exposure can be accomplished as follows: […] Avoiding excessive sun exposure […] Avoiding artificial sources of UV light (eg, tanning beds) […] Using sunscreen […] Wearing protective clothing. […] Patients who are at risk for cSCC but are not able to avoid sun exposure should use sunscreen scrupulously when outdoors. Sunscreen should be reapplied every 30 minutes during acute sun exposure. Several randomized, controlled clinical trials have shown a protective role for the daily application of a broad-spectrum sunscreen in the prevention of new actinic keratoses and new cSCC.
#1 Prevention & Risk Factors for Squamous Cell Carcinoma | Memorial Sloan Kettering Cancer Center
https://www.mskcc.org/cancer-care/types/squamous-cell-carcinoma/risk-factors
The best way to protect yourself from skin cancer is to avoid ultraviolet (UV) light from the suns rays. We recommend you: […] Wear protective clothing such as long-sleeve shirts, wide-brimmed hats, and sunglasses. […] Protect yourself from sun rays by wearing broad-spectrum sunscreen. Broad spectrum means it blocks both types of UV rays (UVA and UVB). […] Apply sunscreen with an SPF of 30 or higher 30 minutes before going outside. Do this even on cloudy days and in the winter. […] Apply a thick layer of sunscreen, about 2 tablespoons, on your face and body. […] Reapply sunscreen every 2 hours and after swimming, toweling, or sweating. […] Stay out of the sun from 10 a.m. to 4 p.m. when rays are the strongest. […] Get into the shade whenever possible. […] Do not use indoor tanning machines.
#1 Squamous Cell Skin Cancer – UF Health
https://ufhealth.org/conditions-and-treatments/squamous-cell-skin-cancer
Experts disagree about the value of routine skin examinations by your provider. But all agree it’s important to know your own skin and to contact your provider if you notice anything unusual. […] The best way to prevent skin cancer is to reduce your exposure to sunlight. Always use sunscreen: […] Apply sunscreen with sun protection factor (SPF) of at least 30, even when you are going outdoors for a short time. […] Apply a large amount of sunscreen on all exposed areas, including ears and feet. […] Look for sunscreen that blocks both UVA and UVB light. […] Use a water-resistant sunscreen. […] Apply sunscreen at least 30 minutes before going out. Follow package instructions about how often to reapply. Be sure to reapply after swimming or sweating. […] Use sunscreen in winter and on cloudy days too.
#1 Prolonged prevention of squamous cell carcinoma of the skin by regular sunscreen use – PubMed
https://pubmed.ncbi.nlm.nih.gov/17132769/
Half of all cancers in the United States are skin cancers. We have previously shown in a 4.5-year randomized controlled trial in an Australian community that squamous cell carcinomas (SCC) but not basal cell carcinomas (BCC) can be prevented by regular sunscreen application to the head, neck, hands, and forearms. […] Regular application of sunscreen has prolonged preventive effects on SCC but with no clear benefit in reducing BCC.
#1 Basal Cell and Squamous Cell Carcinoma | Conditions | UCSF Health
https://www.ucsfhealth.org/conditions/basal-cell-and-squamous-cell-carcinoma
Skin cancer is largely preventable, and if caught early, it’s usually curable. It’s important to take precautions when spending time outdoors. […] Organ transplant patients have up to a 100-fold higher risk of developing skin cancer than the general population. Learn about precautions to take and follow-up care. […] Clothing is a simple, effective sun protection tool that shades the skin from ultraviolet A (UVA), or long wave, and ultraviolet B (UVB), or short wave, rays. […] All sunscreens have a sun protection factor (SPF) rating that indicates how long a sunscreen remains effective on the skin. Learn more.
#1 5 steps to help prevent skin cancer – Mayo Clinic Health System
https://www.mayoclinichealthsystem.org/hometown-health/speaking-of-health/simple-steps-to-prevent-skin-cancer
In parts of the country where winter seems to drag on forever, spring and summer are exciting seasons. Naturally, your skin’s exposure to the sun increases during this time of year, which results in a greater risk of skin damage, including development of skin cancer. The good news? Most skin cancers are preventable. […] Leading medical experts, including Mayo Clinic, recommend these five steps for preventing skin cancer: Avoid the sun between 10 a.m. and 4 p.m., which are the peak hours of sun strength in North America, even in the winter and on cloudy days. Wear sunscreen â at least sun protection factor (SPF) 30 â throughout the entire year. Reapply sunscreen every two hours or more frequently if you’re swimming or sweating. Wear sun-protective clothing with ultraviolet protection factor (UPF) of 50+, which blocks 98% of the sun’s rays. Hats with wide brims and sun-protective clothing that covers your arms and legs are helpful to protect your skin from harmful UV damage. Sunscreen doesn’t block all UV rays, which cause skin cancer. Avoid tanning beds. Tanning beds operate with UV lights, damaging your skin and potentially leading to cancer. Self-check your skin. If you notice differences, talk with your health care team. […] Have fun as the warm days roll in, but always keep skin cancer prevention in mind.
#1 Diagnosis and Treatment of Basal Cell and Squamous Cell Carcinoma | AAFP
https://www.aafp.org/pubs/afp/issues/2012/0715/p161.html/1000
The U.S. Preventive Services Task Force has found insufficient evidence to recommend for or against routine screening for skin cancer using whole-body skin examination, but recommends that physicians remain alert for skin lesions with malignant features when performing physical examinations for other reasons. […] The American Cancer Society recommends a cancer-related checkup, including skin examination, every three years in patients 20 to 40 years of age and yearly in patients older than 40 years. It also recommends that patients perform a skin self-examination monthly. […] Use of any tanning device may increase the risk of squamous cell carcinoma by 2.5-fold and the risk of basal cell carcinoma by 1.5-fold, even after adjusting for history of sun exposure. […] Although major guidelines for adults do not currently address the use of tanning devices, the Centers for Disease Control and Prevention recommends against the use of tanning beds and lamps in its guidelines for preventing skin cancer in school children.
#1 Squamous Cell Skin Cancer – UF Health
https://ufhealth.org/conditions-and-treatments/squamous-cell-skin-cancer
Other measures to help you avoid too much sun exposure: […] Ultraviolet light is most intense between 10 a.m. and 4 p.m. So try to avoid the sun during these hours. […] Protect your skin by wearing wide-brim hats, long-sleeve shirts, long skirts, or pants. You can also buy sun-protective clothing. […] Avoid surfaces that reflect light more, such as water, sand, concrete, and areas that are painted white. […] The higher the altitude, the faster your skin burns. […] Do not use sun lamps and tanning beds (salons). Spending 15 to 20 minutes at a tanning salon is as dangerous as a day spent in the sun.
#1 Basal and Squamous Cell Skin Cancer Prevention | Skin Cancer Prevention | American Cancer Society
https://www.cancer.org/cancer/types/basal-and-squamous-cell-skin-cancer/causes-risks-prevention/prevention.html
Exposure to certain chemicals, such as arsenic, can increase a persons risk of skin cancer. […] Checking your skin regularly may help you spot any new growths or abnormal areas and show them to your doctor before they even have a chance to turn into skin cancer. […] Smoking has been linked to an increased risk of squamous cell skin cancer, as well as to many other types of cancer. […] Having a weakened immune system increases your risk of getting skin cancer. It can also make skin cancers harder to treat. […] Some people at increased risk for skin cancer, such as people with certain inherited conditions or a weakened immune system, might be helped by medicines that could lower their risk (known as chemoprevention).
#1 Living with Squamous Cell Skin Cancer: Secondary Prevention – Skin Cancer Consortium for Advocacy, Research, & Education
https://skincancerinfo.org/scsc-living-with-secondary-prevention/
After the initial surgical procedure or other treatment for your squamous cell skin cancer, you can take proactive measures to prevent additional tumors from forming (secondary prevention). These preventive steps include keeping an appropriate follow-up medical appointment schedule, conducting skin self-examinations, and practicing sun safety. […] After you have completed your treatment for squamous cell skin cancer, it is important to keep all follow-up medical appointments, because you are at risk of your squamous cell skin cancer returning (recurring) as well as for developing a new squamous cell skin cancer. […] Its important that you conduct skin self-examinations on a regular basis. These exams are an important aspect of early detection for squamous cell skin cancer and other skin cancers.
#1 Squamous cell carcinoma of the skin – Symptoms and causes – Mayo Clinic
https://www.mayoclinic.org/diseases-conditions/squamous-cell-carcinoma/symptoms-causes/syc-20352480
Don’t use tanning beds. The lights in tanning beds give off UV radiation. Using tanning beds increases the risk of skin cancer. […] Check your skin often and report changes to your health care team. Look at your skin often for new growths. Look for changes in moles, freckles, bumps and birthmarks. Use mirrors to check your face, neck, ears and scalp. Look at your chest and trunk and the tops and undersides of your arms and hands. Look at the front and back of your legs and your feet. Look at the bottom of the feet and the spaces between your toes. Also check your genital area and between your buttocks.
#1 Squamous Cell Carcinoma | Skin Cancer And Reconstructive Surgery Center
https://ocskincancer.com/squamous-cell-carcinoma/
Prevention of squamous cell carcinoma is best accomplished by using proper sun protection, practicing sun safety, and doing self-examinations for early detection. When found early and treated properly, the cure rate is more than 95%. […] Sun protection includes the use of a broad spectrum sunscreen first thing in the morning and every two hours throughout the day if you plan to be outside. Cover up with hats, sunglasses, and protective clothing. […] To practice sun safety, avoid peak hours of sunlight (10 am to 4 pm), and whenever possible, seek shade on a sunny day. […] Self examinations should be performed monthly. Refer to the ABCDEs of Melanoma, and notify a dermatologist if you see anything suspicious, especially pimple-like bumps that fail to heal after three weeks and scab or rash-like lesions that recur (come and go) over periods of time.
#1 Spot Check | Squamous cell carcinoma
https://www.spotcheck.clinic/conditions/skin-cancers/scc/
Regular skin checks will help detect evidence of the cancer returning and allow detection of new skin cancers. […] For most people, 12-monthy skin checks are recommended. If thereâs a history of multiple or high-risk skin cancers, we may recommend 6-monthly skin checks. […] Treating solar keratoses sometimes develop into squamous cell carcinoma. Treating them may reduce the risk of SCC. Treatment options include cryotherapy (freezing) of individual solar keratoses and prescription creams, photodynamic therapy or fractional laser treatment of larger areas. […] Because the majority of squamous cell carcinomas are caused by ultraviolet radiation, avoiding excessive sun exposure is the most important measure for prevention. The risk of squamous cell carcinoma is increased by sun exposure in later life, so reduction of sun exposure at any age can help reduce the risk.

Treatment of sun-damaged skin to prevent skin cancer: Topical fluorouracil. […] A study showed that topical fluorouracil applied on sun-damaged skin daily for up to 4 weeks prevented new actinic keratoses from developing. […] Sunscreen has been shown to prevent sunburns and actinic keratoses that may become squamous cell carcinoma, and to decrease the signs and symptoms of existing actinic keratoses. […] Although protecting the skin and eyes from the sun has not been proven to lower the chance of getting skin cancer, skin experts suggest the following: Use sunscreen that protects against UV radiation. […] Chemoprevention is the use of drugs, vitamins, or other agents to try to reduce the risk of cancer. […] Studies have shown that selenium (taken in brewer’s yeast tablets) does not lower the risk of basal cell carcinoma, and may increase the risk of squamous cell carcinoma.

Results of a new randomized, double-blinded, controlled clinical trial in veterans showed a 75 percent reduction in the risk of needing surgery to treat a squamous cell carcinoma for a year after applying a skin cream for up to four weeks. […] New results from a clinical trial involving more than 900 military veterans at high risk for keratinocyte carcinoma skin cancer provides evidence that using the generic skin cream fluorouracil 5 percent for two to four weeks may reduce the risk of a squamous cell carcinoma (SCC) needing surgery by 75 percent within a year. […] The finding that less than one months use of fluorouracil 5% (5-FU) appeared to prevent cancer for up to a year is encouraging. […] Meanwhile, current means for preventing new carcinomas in high-risk patients sunscreen or oral medications cease to work as soon as they are no longer used. But in the new study, 5-FU appeared to provide prolonged protection after discontinuation and could be combined with sunscreen.

Skin cancer precursor immunotherapy for squamous cell carcinoma prevention […] Topical calcipotriol plus 5-fluorouracil (5-FU) combination is an effective immunotherapy against actinic keratosis (AK), which is a precursor to squamous cell carcinoma (SCC). However, the long-term effectiveness of calcipotriol plus 5-FU treatment for SCC prevention is unknown. […] A short course of calcipotriol plus 5-FU treatment on the face and scalp is associated with induction of robust T cell immunity and Trm formation against AKs and significantly lowers the risk of SCC development within 3 years of treatment. […] Therefore, skin cancer prevention is an urgent unmet need. […] Treatment for AKs is recommended due to their premalignant nature. […] While an individual AK is estimated to have a less than 1% chance of progressing to SCC within 1 year, the majority of SCCs arise from existing AKs, highlighting their shared origin. […] The only agent that has been shown to reduce the risk of SCC after treatment cessation is 5-FU, and this benefit is no longer apparent 2 years after treatment. […] Our prospective cohort study has revealed that a 4-day course of calcipotriol plus 5-FU immunotherapy, which effectively eliminated AKs in a double-blind randomized controlled trial, is associated with a reduced long-term risk of SCC. […] In conclusion, we report that a 4-day course of calcipotriol plus 5-FU immunotherapy directed against AKs on the face and scalp reduces the risk of SCC 3 years following treatment.

Squamous cell carcinoma (SCC) of the skin is a common cancer in white populations, and the incidence appears to be increasing. Sun exposure is thought to be the most important environmental risk factor for the disease, and a number of studies have confirmed this association, without assessing how character, duration and timing of exposure relates to risk. Age is also strongly associated with risk. […] These results reflect previous study findings, and suggest people with light skin, blond or red hair, who tend to burn rather than tan, are at greater risk of SCC. A propensity to freckle has also been reported as more common in individuals with SCC. Another study found a history of severe sunburn is characteristic of patients with SCC. In addition, one other study reported Southern European origin reduces risk.

Cutaneous squamous cell carcinoma (cSCC) is the second most common nonmelanoma (keratinocyte) cancer after basal cell carcinoma, accounting for approximately 20 percent of all skin cancers. Its incidence is increasing worldwide; in the United States, it has been estimated that over 700,000 persons were treated for cSCC in 2012. As the diagnosis and treatment of keratinocyte carcinomas imposes a high burden on health care systems, there is a need for effective primary and secondary prevention strategies. […] Primary prevention is aimed at reducing the exposure to known risk factors by using behavioral and environmental interventions, such as decreasing ultraviolet light exposure or arsenic contamination of water. Secondary prevention involves early detection and treatment of skin cancer and precursor lesions. Chemoprevention is a secondary prevention strategy for patients at high risk of developing multiple cSCCs (eg, patients with a history of cSCC, extensive sun-induced skin damage and actinic keratosis, immunosuppressed patients). […] This topic will review primary and secondary prevention strategies for cSCC.
