  Basal cell carcinoma is the most common cutaneous malignancy, affecting close to one in five Americans. Although rarely fatal, basal cell carcinoma can be highly destructive and disfigure local tissues when treatment is inadequate or delayed. […] Basal cell carcinoma (BCC), previously known as basal cell epithelioma, is the most common cancer in Humans. BCC mostly arises on sun-damaged skin and rarely develops on the mucous membranes or palms and soles. Basal cell carcinoma is usually a slow-growing tumor for which metastases are rare. Although rarely fatal, BCC can be highly destructive and disfigure local tissues when treatment is inadequate or delayed. On clinical examination, BCC usually appears as flesh- or pink-colored, pearly papules with overlying ulceration or telangiectatic vessels. BCC occurs on the head or neck in the majority of cases, but can involve the trunk and extremities.

  https://www.skincancer.org/skin-cancer-information/basal-cell-carcinoma/

  Basal cell carcinoma (BCC) is the most common form of skin cancer and the most frequently occurring form of all cancers. In the U.S. alone, an estimated 3.6 million cases are diagnosed each year. BCCs arise from abnormal, uncontrolled growth of basal cells. […] Because BCCs grow slowly, most are curable and cause minimal damage when caught and treated early. Understanding BCC causes, risk factors and warning signs can help you detect them early, when they are easiest to treat and cure. […] BCCs can look like open sores, red patches, pink growths, shiny bumps, scars or growths with slightly elevated, rolled edges and/or a central indentation. At times, BCCs may ooze, crust, itch or bleed. The lesions commonly arise in sun-exposed areas of the body. […] An open sore that does not heal […] A shiny bump or nodule

  https://www.mayoclinic.org/diseases-conditions/basal-cell-carcinoma/symptoms-causes/syc-20354187

  Basal cell carcinoma usually develops on sun-exposed parts of your body, especially your head and neck. Less often, basal cell carcinoma can develop on parts of your body usually protected from the sun, such as the genitals. […] Basal cell carcinoma appears as a change in the skin, such as a growth or a sore that won’t heal. These changes in the skin (lesions) usually have one of the following characteristics: […] A shiny, skin-colored bump that’s translucent, meaning you can see a bit through the surface. The bump can look pearly white or pink on white skin. On brown and Black skin, the bump often looks brown or glossy black and has a rolled border. […] A brown, black or blue lesion or a lesion with dark spots with a slightly raised, translucent border. […] A flat, scaly patch with a raised edge. Over time, these patches can grow quite large. […] A white, waxy, scar-like lesion without a clearly defined border.

• #4 Basal Cell Carcinoma Warning Signs and Images

  https://www.skincancer.org/skin-cancer-information/basal-cell-carcinoma/bcc-warning-signs-images/

  Understanding what basal cell carcinoma (BCC) looks like is important. With early detection and treatment, almost all basal cell skin cancers can be successfully removed without complications. […] Look out for BCC warning signs, including new, changing or unusual skin growths, so you can spot skin cancers early, when they are easiest to treat and cure. […] Check for BCCs where your skin is most exposed to the sun, especially the face, ears, neck, scalp, chest, shoulders and back, but remember that they can occur anywhere on the body. Frequently, two or more of these warning signs and symptoms are apparent in a BCC tumor. […] An open sore that does not heal, and may bleed, ooze or crust. The sore might persist for weeks, or appear to heal and then come back. […] A reddish patch or irritated area, on the face, chest, shoulder, arm or leg that may crust, itch, hurt or cause no discomfort.

• #5 Basal Cell Carcinoma Clinical Presentation: History, Physical Examination

  https://emedicine.medscape.com/article/276624-clinical

  Patients presenting with basal cell carcinoma (BCC) often report a slowly enlarging lesion that does not heal and that bleeds when traumatized. […] Consider BCC in any patient with a history of a sore or skin anomaly that does not heal within 3-4 weeks and occurs on sun-exposed skin, especially if it is dimpled in the middle. These tumors may take many months or years to reach even 1 cm in diameter. […] Characteristic features of BCC tumors include the following: Waxy papules with central depression, Pearly appearance, Erosion or ulceration, often central, Bleeding, especially when traumatized, Crusting, Rolled (raised) border, Translucency, Telangiectases over the surface, Slow growing (0.5 cm in 1-2 y). […] BCC usually appears as a flat, firm, pale area that is small, raised, pink or red, translucent, shiny, and waxy, and the area may bleed following minor injury.

• #6 Basal Cell Carcinoma Clinical Presentation: History, Physical Examination

  https://emedicine.medscape.com/article/276624-clinical

  The lesion grows slowly, is not painful, and does not itch. […] In patients with recurrent or deeply infiltrative tumors, involvement of the facial nerve or branches of the trigeminal nerve should be investigated. […] BCC seldom causes regional or distant metastasis, with the exception of the metatypical basosquamous type. […] Ulceration, bleeding, and crusting are uncommon and these tumors are commonly mistaken for scar tissue. […] Superficial BCCs occur mostly on the upper trunk or shoulders. This type of BCC grows slowly, has minimal tendency to be invasive, and appears clinically as an erythematous, well-circumscribed patch or plaque, often with a whitish scale. […] The tumor often appears multicentric, with areas of clinically normal skin intervening among clinically involved areas.

• #7 Basal Cell Carcinoma Warning Signs and Images

  https://www.skincancer.org/skin-cancer-information/basal-cell-carcinoma/bcc-warning-signs-images/

  A shiny bump or nodule that is pearly or clear, pink, red or white. The bump can also be pigmented (tan, black or brown), especially in people of color, and can be mistaken for a normal mole. […] A small pink growth with a slightly raised, rolled edge and a crusted indentation in the center that may develop tiny surface blood vessels over time. […] A scar-like area that is flat white, yellow or waxy in color. The skin appears shiny and taut, often with poorly defined borders. This warning sign may indicate an invasive BCC. […] Keep in mind that BCCs can look different from the pictures and descriptions above. In some people, BCCs resemble noncancerous skin conditions such as psoriasis or eczema. […] A BCC can recur even when it has been carefully removed the first time, because some cancer cells may remain undetectable after surgery and others can form roots that extend beyond what’s visible. BCCs on the nose, ears and lips are more likely to recur, usually within the first two years after surgery. […] Be on the lookout: Pay particular attention to any previously treated site, note changes and consult with your dermatologist. If the BCC does return, your doctor may recommend a different type of treatment, such as Mohs surgery, a highly effective way to prevent and treat recurrences.

• #8 Basal Cell Carcinoma – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK482439/

  BCC typically presents as a shiny, pink- or flesh-colored papule or nodule with surface telangiectasia. The tumor may enlarge and ulcerate, giving the borders a rolled or rodent ulcer appearance. The most common sites for nodular basal cells are the face, especially the nose, cheeks, forehead, nasolabial folds, and eyelids. Patients often give a history of crusting and recurrent bleeding, causing them to seek evaluation. […] The other common clinical variant of BCC is the morpheaform subtype. This tumor frequently presents as white- or flesh-colored with areas of induration and ill-defined borders. Morpheaform BCCs may resemble a scar or plaque of morphea. The lesion’s surface is typically smooth, although crusts with underlying erosions or ulcerations, as well as superimposed papules, may be observed. Telangiectasias also may be present. The biologic behavior is usually more aggressive, with extensive local destruction. […] BCC is rarely associated with a fatal outcome. Its prognosis is mainly related to its potential risk of recurrence after initial therapy. The risk of recurrence depends on BCC location and BCC clinical and histopathological features.

  https://my.clevelandclinic.org/health/diseases/4581-basal-cell-carcinoma

  Basal cell carcinoma is a type of skin cancer that causes a lump, bump or lesion to form on the outside layer of your skin (epidermis). These lumps form on areas of your skin that get a lot of sun exposure. Treatment to remove cancer from your skin leads to a positive outlook. […] Basal cell carcinoma looks like a small, sometimes shiny bump or scaly flat patch on your skin that slowly grows over time. […] Signs of basal cell carcinoma include: Lumps, bumps, pimples, scabs or scaly lesions on your skin. The lump may be slightly see-through (translucent) and close to your normal skin color or white to pink, brown to black or black to blue. The lump may appear shinier than the skin around it with tiny visible blood vessels. The lump may grow slowly over time. The lump may be itchy or painful. The lump may form an ulcer, which can ooze clear fluid or bleed with contact.

  Basal cell carcinoma (BCC) is a type of skin cancer that can show up on the skin in many ways. Sometimes, it can be mistaken for a harmless pimple, scar, or sore. Most basal cell carcinoma’s grow slowly. […] This skin cancer often develops on the head or neck and looks like a shiny, raised, and round growth. […] If you find any of the following signs on your skin, see a board-certified dermatologist. […] A sore that doesn’t heal (or heals and returns) and may bleed, ooze, or crust over. […] For many people, the only sign of this skin cancer is a slow-growing bump, sore-like growth, or rough-feeling area on their skin. However, some people develop symptoms where they have this skin cancer. Symptoms include: Numbness, A pins-and-needles sensation, Extreme sensitivity, Itching. […] Many people find it when they notice a spot, lump, or scaly area on their skin that is growing or feels different from the rest of their skin.

  https://www.medstarhealth.org/services/basal-cell-carcinoma-symptoms-and-stages

  Basal cell carcinoma is the most common type of skin cancer in the United States. These abnormal growths develop in the outermost layer of skin that is frequently exposed to the sun, like the head and neck. For many, it looks like a pimple or red sore that doesn’t go away. […] Like other skin cancers, basal cell carcinoma symptoms can involve any new or unusual skin growths. Each type of skin cancer looks different, and the appearance of basal cell cancer varies person-to-person. You should talk to your doctor if you notice: A red or scaly patch of skin that may or may not be itchy or painful, A small, pimple-like growth that is pearly, pink, red, white, black, or brown, An open sore that persists, A mark that looks like a scar, or waxy growth, A dome shape with blood vessels visible in the center. […] If you see something on your skin that you think is concerning, it’s always best to get it checked sooner rather than later. That’s because skin cancer is often easily treated when found in early stages.

  A reddish patch or irritated area […] A scar-like area that is flat white, yellow or waxy in color […] A small pink growth with a slightly raised, rolled edge and a crusted indentation in the center. […] BCCs rarely spread beyond the original tumor site. But these lesions can grow and become disfiguring and dangerous. Untreated BCCs can become locally invasive, grow wide and deep into the skin and destroy skin, tissue and bone. The longer you wait to get treatment, the more likely it is that the BCC will recur, sometimes repeatedly. […] There are some highly unusual, aggressive cases when BCC spreads to other parts of the body. In even rarer instances, this type of BCC can become life-threatening. […] Basal cell carcinoma is quite common. The number of reported cases in the U.S. has steadily increased. An estimated 3.6 million Americans are diagnosed with BCC each year. More than one out of every three new cancers are skin cancers, and the vast majority are BCCs.

  Skin cancer, including basal and squamous cell skin cancers, often don’t cause bothersome symptoms until they have grown quite large. Then, skin cancer symptoms may include itching, bleeding, or even pain. But if you know what to look for, you can spot signs of skin cancer when its still small and easier to treat. […] Basal cell cancers (BCCs) usually develop on areas exposed to the sun, especially the face, head, neck, and arms, but they can occur anywhere on the body. […] In people with lighter-colored skin, basal cell skin cancer can appear as: Small, pink or red, translucent, shiny, pearly bumps, which might have blue, brown, or black areas; Pink growths with raised edges and a lower area in their center, which might contain abnormal blood vessels spreading out like the spokes of a wheel; Flat, firm, pale or yellow areas, similar to a scar; Raised reddish patches that might be itchy; Open sores (which may have oozing or crusted areas) that dont heal, or that heal and then come back. […] Basal cell cancers are often fragile and might bleed after shaving or after a minor injury. If you have a sore or cut that is taking longer than a week or so to heal, check with your doctor, because it could be a sign of basal cell skin cancer.

  https://www.merckmanuals.com/home/skin-disorders/skin-cancers/basal-cell-carcinoma

  Usually, a small, shiny bump appears on the skin and enlarges slowly. […] The bumps may break open and form a scab, sometimes with bleeding, or become flat, resembling a scar. […] The tumors enlarge very slowly, sometimes so slowly that they go unnoticed as new growths. However, the growth rate varies greatly from tumor to tumor, with some growing as much as inch (about 1 centimeter) in a year. […] Basal cell carcinomas rarely spread (metastasize) to other parts of the body. Instead, they invade and slowly destroy surrounding tissues. When basal cell carcinomas grow near the eyes, ears, mouth, bone, or brain, the consequences of spread can be serious and can lead to death. Yet, for most people, the tumors simply grow slowly into the skin. […] The nodular type of basal cell carcinoma usually begins as small, shiny, firm, almost clear to pink in color, raised growth. After a few months or years, visible dilated blood vessels (telangiectases) may appear on the surface, and the center may break open and form a scab. The border of the cancer is sometimes thickened and pearly white. The cancer may alternately bleed and form a scab and heal, leading a person to falsely think that it is a sore rather than a cancer. […] Other types of basal cell carcinomas vary greatly in appearance. For example, the superficial type appears as flat, thin, red or pink patches, and the morpheaform type appears as thicker flesh-colored or light red patches that look somewhat like scars.

  https://www.mskcc.org/cancer-care/types/basal-cell-carcinoma

  This type of skin cancer rarely causes pain when its developing. However, it may bleed after a minor injury, then form a scab and heal. Since a spot like this can scab and heal over and over again for months or years without seeming to grow, its easy to think that it is just a sore or a wound. […] Basal cell carcinomas rarely spread to other parts of the body, and deaths from this disease are very rare. However, because basal cell carcinomas often occur on the face, they can cause serious cosmetic damage and functional difficulties if not diagnosed and treated early.

• #16 Basal Cell Carcinoma: What it is, Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/4581-basal-cell-carcinoma

  Basal cell carcinomas most commonly appear on areas of your body exposed to the sun. The most common places to have BCC include: Face. Scalp. Nose. Eyelids. Legs. Ears. Arms. […] If you dont receive treatment for basal cell carcinoma, the skin cancer can slowly grow in size and invade deeper tissues like muscle and bone and cartilage. The BCC may become painful and ulcerated, which can cause bleeding and infection. In extremely rare cases, basal cell carcinoma can spread to other parts of your body and cause life-threatening side effects. […] The prognosis for people diagnosed with basal cell carcinoma (BCC) is excellent. BCC will rarely spread to other areas of your body and cause harm. Theres a low chance that BCC can return after you have it removed. If you notice a new lesion around the scar from previous treatment, visit your healthcare provider immediately.

• #17 Basal Cell Carcinoma | Memorial Sloan Kettering Cancer Center

  https://www.mskcc.org/cancer-care/types/basal-cell-carcinoma

  Basal cell carcinomas are most commonly found on the face, neck, hands, or other parts of the body that are frequently exposed to the sun. […] The first sign of basal cell carcinoma is an unusual growth on your skin. You may notice a waxy lump or a small, smooth, shiny, or pale growth. Or there may not be a lump at all, but instead you notice a flat spot that looks slightly different from the rest of your skin. […] Some basal cell carcinomas develop so slowly that you only notice them after theyve been there for a while. […] Basal cell carcinoma can appear in one of several ways: a small, smooth, shiny, or pale growth; a waxy-looking lump; a red patch or irritated area; a small, pink, pearly bump; a white or yellow scar-like area; a smooth growth with a dent or dimple in the middle; a bleeding or oozing sore.

  Painless raised area of skin that may be shiny with small blood vessel running over it or ulceration. […] It often appears as a painless raised area of skin, which may be shiny with small blood vessels running over it. […] It may also present as a raised area with ulceration. […] Basal-cell cancer grows slowly and can damage the tissue around it, but it is unlikely to spread to distant areas or result in death. […] Individuals with basal-cell carcinoma typically present with a shiny, pearly skin nodule. However, superficial basal-cell cancer can present as a red patch similar to eczema. Infiltrative or morpheaform basal-cell cancers can present as a skin thickening or scar tissue making diagnosis difficult without using tactile sensation and a skin biopsy. […] Prognosis is excellent if the appropriate method of treatment is used in early primary basal-cell cancers. Recurrent cancers are much harder to cure, with a higher recurrence rate with any method of treatment. Although basal-cell carcinoma rarely metastasizes, it grows locally with invasion and destruction of local tissues. The cancer can impinge on vital structures like nerves and result in loss of sensation or loss of function or rarely death. The vast majority of cases can be successfully treated before serious complications occur. The recurrence rate for the above treatment options ranges from 50 percent to 1 percent or less.

• #19 What Are the Stages of Basal Cell Carcinoma?

  https://www.dermla.com/sbcblog/what-are-the-stages-of-basal-cell-carcinoma/

  Basal cell carcinoma is a type of skin cancer that usually starts as a small, painless lump on the head, neck, or shoulders. If left untreated, this tumor can grow and spread to other parts of the body. […] During the first stage of basal cell carcinoma, the tumor is typically small and has not reached deeper layers of the skin. […] During locally advanced disease, which typically occurs after several years with no treatment or if an earlier treatment was unsuccessful, the tumor has grown deeper into the underlying tissue and may have started to spread to nearby lymph nodes. […] In the final stage of basal cell carcinoma, also known as metastatic disease, the tumor has spread throughout the body, including places such as the lungs or liver. […] Keep in mind that it is very rare for BCC to spread elsewhere it takes many years and usually happens to people who have severely compromised immune systems.

  Certain features may increase the risk of the cancer spreading or recurring, and these may also be used to stage basal cell carcinomas. These include: […] In stage 1, the cancer is less than 2 centimeters, about 4/5 of an inch across, has not spread to nearby lymph nodes or organs, and has one or fewer high-risk features. […] In stage 2, the cancer is larger than 2 centimeters across, and has not spread to nearby organs or lymph nodes, or a tumor of any size with two or more high-risk features. […] In stage 3, the cancer has spread into facial bones or one nearby lymph node, but not to other organs.

  The sun-exposed areas of the head and neck are the most commonly involved sites. Approximately 80% occur on the head and neck, with the rest mainly on the trunk and lower limbs. […] Early lesions are often small, translucent or pearly and have raised areas with telangiectasia. […] The classic rodent ulcer has an indurated edge and ulcerated centre. It is slow-growing but can spread deeply to cause considerable destruction. […] Mortality is low because basal cell carcinomas rarely metastasise. […] Recurrent tumours have poorer cure rates than primary tumours. […] Following development of a BCC, patients are at significantly increased risk of developing subsequent BCCs at other sites. […] High-risk groups for the development of further BCC include patients with truncal BCC and those presenting with tumour clusters. […] Patients with BCC also have an increased risk of developing SCC and malignant melanoma. […] There may also be a small increased risk of other malignancies, such as cancer of the lung, thyroid, mouth, breast and cervix and also non-Hodgkin’s lymphoma.

  The exact symptoms of metastatic BCC can vary depending upon where the cancer has spread to. However, some general symptoms to look for are: fatigue, weakness, unintended weight loss, shortness of breath, pain in the area of the metastatic site. […] BCC is typically a slow growing cancer. That means that it may take several years for it to become advanced. […] Generally speaking, the outlook for people with advanced BCC is poorer than that for people with an earlier stage of BCC. This is because the cancer has spread further and, as such, can be more challenging to treat. […] BCC becomes advanced when it has spread deeper into surrounding tissues or to more distant tissues in the body. Since BCC is a slow growing cancer, this typically happens over a period of several years. […] Advanced BCC is more difficult to treat than early BCC, often due to the location, size, and extent of the cancer. However, newer systemic treatments can help to improve your outlook when surgery or radiation therapy isn’t recommended.
