• #2 Breast Lumps: Types, Benign, Moveable, Causes & Diagnosis

  https://my.clevelandclinic.org/health/symptoms/6906-breast-lumps

  A breast lump is a mass or growth that develops in your breast. While a breast lump can be a sign of breast cancer, its usually benign (not cancerous). In fact, 8 out of 10 breast lumps are noncancerous. If you feel a lump in your breast or under your arm, try not to panic. A healthcare provider can figure out the cause of the breast lump and determine if you need tests or treatment. […] Breast lumps are one of the symptoms of breast cancer. But, often, breast lumps arent cancerous. Several other conditions can cause breast lumps. […] Talk to your healthcare provider if you notice a breast lump. If it is cancer, treatment is more successful when started early. […] If you feel a lump or anything unusual in your breast, see a healthcare provider. […] Depending on the exam and any imaging results at your initial appointment, your healthcare provider will recommend what comes next.

• #3 New Palpable Breast Mass – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK560757/

  A palpable breast mass requires careful evaluation as this is the most common presenting symptom of breast cancer, although many cases are proven to be benign. A breast mass is associated with a broad spectrum of differential diagnoses, from benign breast abnormalities to advanced malignancies; therefore, a structured evaluation approach is required to appropriately assess these lesions without submitting patients to unnecessary procedures. […] If imaging or clinical findings are suspicious, tissue sampling is necessary, with core needle biopsy being the preferred method due to its accuracy and lower complication rate. Accurate and early diagnosis relies on correlating clinical and imaging findings, ensuring appropriate follow-up or biopsy when needed. […] Although the majority of these masses are associated with benign breast conditions, patients with palpable breast masses have an increased likelihood of having a breast malignancy. Therefore, appropriate evaluation of any patient with a palpable breast mass is essential to optimizing outcomes.

• #4 Diagnosis of breast cancer | Canadian Cancer Society

  https://cancer.ca/en/cancer-information/cancer-types/breast/diagnosis

  Diagnosis is the process of finding out the cause of a health problem. Diagnosing breast cancer usually begins when you find a lump in your breast or a screening mammography suggests a problem with the breast. Your doctor will ask you about any symptoms you have and do a physical exam. Based on this information, your doctor may refer you to a specialist or order tests to check for breast cancer or other health problems. […] The following tests are usually used to rule out or diagnose breast cancer. Many of the same tests used to diagnose cancer are used to find out the stage (how far the cancer has progressed). Your doctor may also order other tests to check your general health and to help plan your treatment. […] A biopsy is the only definite way to diagnose breast cancer. During a biopsy, the doctor removes tissues or cells from the body so they can be tested in a lab. A report from the pathologist will confirm whether or not cancer cells are found in the sample.

• #7 Common Breast Problems | AAFP

  https://www.aafp.org/pubs/afp/issues/2019/0415/p505.html

  Palpable breast masses, mastalgia, and nipple discharge are commonly encountered symptoms in outpatient practice, causing significant patient anxiety and precipitating medical consultation. The initial workup includes a detailed clinical history and physical examination. Women presenting with a breast mass will require imaging and further assessment to exclude cancer. Diagnostic mammography is usually preferred, but ultrasonography is more sensitive in women younger than 30 years. Any suspicious mass detected on physical examination, mammography, or ultrasonography should undergo biopsy. In most cases, a core needle biopsy should be performed with imaging guidance for evaluation of a suspicious mass. […] Breast masses are associated with an increased risk of breast cancer. Patients presenting with a palpable breast mass should be evaluated with a detailed history, clinical breast examination (CBE), and, for almost all women, imaging. A thorough CBE in a symptomatic patient can guide the clinician’s level of concern and help determine the next step in management.

  However, even if the mammogram or ultrasound is reported as benign, the standard of care requires that the physician further investigate a solid, persistent, and dominant mass by fine needle or tissue biopsy. […] Relying on a negative mammogram to rule out cancer in a woman with a clinically suspicious breast mass is unacceptable. […] False negative results from mammography in women with palpable breast masses have been reported to be as high as twenty-two percent (22%). […] Some of the features which raise the index of suspicion for breast cancer include a mass which has a hard or gritty texture, is fixed or immobile, has irregular borders, and does not vary in size during the menstrual cycle. […] In conjunction with other organizations, the American College of Radiologists has developed a uniform system for classifying and reporting the level of suspicion for breast cancer on mammography or ultrasound, and what action, if any, should be taken in follow-up.

  Although CBE has poor predictive value for determining whether a breast mass is cancerous, some features of breast masses may help distinguish between benign and malignant lesions. […] The sensitivity of CBE ranges from 49% to 69%, and specificity is 86% to 99%. Detection of malignancy increases when imaging is added to the evaluation. […] Diagnostic mammography is the most appropriate initial imaging modality for women 40 years and older who present with a breast mass, whereas ultrasonography is recommended for women younger than 30 years. […] Because of the imperfect sensitivity and specificity of CBE and imaging, patients should be referred for tissue sampling if suspicious findings are noted at any stage of the evaluation, regardless of benign findings at other stages. A highly suspicious breast mass found on CBE should be biopsied regardless of imaging findings, and suspicious masses on imaging should be biopsied even if the CBE suggested benign findings. […] In most cases, a core needle biopsy should be performed for evaluation of a suspicious mass.

  https://www.aafp.org/pubs/afp/issues/2005/0501/p1731.html

  An efficient and accurate evaluation can maximize cancer detection and minimize unnecessary testing and procedures. […] Ultrasonography-guided CNB should be considered to diagnose malignancy in women with palpable breast lesions. […] Diagnostic mammography is indicated in women older than 40 years if FNA reveals a solid mass. […] Excisional biopsy should be performed in women with clinically suspicious lesions, or lesions that are equivocal on imaging, FNA, or CNB. […] Digital palpation of the breast is effective in detecting masses and can help determine whether a mass is benign or malignant. […] Despite its accuracy, CBE alone is not adequate for definitive diagnosis of breast cancer. Further evaluation, including follow-up examinations, imaging, and tissue sampling, is required in all patients with breast masses.

  You’ll likely need one or more imaging tests to check for changes in the breasts. These include: Diagnostic mammogram. This is an X-ray of your breasts. During a mammogram, your breasts are compressed between two firm surfaces. Then an X-ray takes black-and-white images. When your healthcare professional orders a diagnostic mammogram, this tells the radiologist who reviews your images that you have a new breast concern. A diagnostic mammogram is different from a screening mammogram, which looks for breast cancer before a person has symptoms.

• #15 Breast Ultrasound in Cancer Diagnosis vs. Mammogram

  https://www.cancercenter.com/cancer-types/breast-cancer/diagnosis-and-detection/breast-ultrasound

  Breast ultrasound is a safe, painless, non-invasive imaging test that uses sound waves to produce pictures of the interior of the breast. It shows breast tissue changes that may not appear on a mammogram and helps to confirm the type of mass, if one is present. […] Ultrasound helps healthcare providers determine whether a mass is solid (and more likely to be cancer) or fluid-filled (such as a benign cyst). […] Breast ultrasound is not typically part of routine breast cancer screening tests. Instead, its used to diagnose abnormalities that appear on other tests or breast lumps that may be felt but dont show up on a mammogram. […] If any areas appear suspicious or unclear, ultrasound testing is often used to detect if the mass is a noncancerous cyst or a solid mass that needs further examination.

  Using a thin needle, fluid is drawn from the lump in your breast. If clear fluid is drawn, the lump is most likely a cyst. If the lump is solid, small tissue samples will be removed and examined in the laboratory. […] We are able to do the biopsy of the breast using ultrasound which allows patients to return to normal activity immediately. […] When the abnormal area in the breast is too small to be felt, radiologists may perform a minimally invasive image-guided biopsy. […] This is another minimally invasive procedure using ultrasound imaging and a core needle to remove suspicious breast tissue. […] In certain cases your physician may recommend using a surgical technique in order to get a better understanding of your breast cancer and determine whether or not the cancer has spread.

[…] HER2 status testing is done to find out if breast cancer cells are making more HER2 protein than normal (called overexpression). This information will help your healthcare team decide which treatments will work best for you. […] A CBC is done to check your general health. Your healthcare team also uses a CBC as a baseline that they can check against future blood counts taken during and after treatment. […] An x-ray uses small doses of radiation to make an image of parts of the body on film. It is used to find out if breast cancer has spread to the lungs. […] A bone scan is done if a woman has bone pain or the level of alkaline phosphatase is higher than normal. Doctors may also order a bone scan if a breast tumour is larger than 5 cm or they can feel lymph nodes under the arm (called axillary lymph nodes). They do not do bone scans for women with stage I breast cancer. […] An MRI is not used routinely to diagnose breast cancer. Doctors may use an MRI to better examine an abnormality found on mammography if they cant find it with other tests or if results from other tests are not clear.

A biopsy is the only diagnostic procedure that can definitely determine if the suspicious area is cancerous. […] The good news is that 80% of women who have a breast biopsy do not have breast cancer. […] When mammogram results come back as abnormal or suspicious, a breast biopsy will likely be performed. […] Core-needle and surgical biopsies are most commonly used on the breast. […] There are several factors that help a doctor decide which type of biopsy to recommend. These include the appearance, size, and location of the suspicious area on the breast. […] Once the biopsy is complete, a specially trained doctor called a pathologist examines the tissue or fluid samples under a microscope, looking for abnormal or cancerous cells. The pathology report, which can take one or two weeks to complete, is sent to the patient’s doctor. It indicates whether the suspicious area is cancerous and provides a full picture of your situation.

  In needle biopsy, a needle is used to aspirate (draw out) fluid or tissue from a breast lump. Compared to a surgical biopsy, a needle aspiration leaves no scarring, and is less invasive and quicker to perform. However, unlike surgical biopsy, needle biopsies cannot remove the entire lesion and misdiagnosis may occur. […] Fine needle aspiration is only recommended for suspicious areas that can be felt (palpable masses). It is also done as a quick method to obtain sample of a breast lump felt during a clinical breast exam. […] The evaluation can be incomplete or inaccurate because the tissue sample is very small. Fine needle aspiration can miss a cancerous tumor and take a sample of normal cells instead. When used alone, up to about 10% of breast cancers may be missed. […] A core needle biopsy may also provide a more accurate analysis and diagnosis than fine needle aspiration because tissue is removed, rather than just cells.

Fine needle aspiration can miss a cancerous tumor and take a sample of normal cells instead. When used alone, up to about 10% of breast cancers may be missed. […] A core needle biopsy may also provide a more accurate analysis and diagnosis than fine needle aspiration because tissue is removed, rather than just cells.

  Although CBE has poor predictive value for determining whether a breast mass is cancerous, some features of breast masses may help distinguish between benign and malignant lesions. […] The sensitivity of CBE ranges from 49% to 69%, and specificity is 86% to 99%. Detection of malignancy increases when imaging is added to the evaluation. […] Diagnostic mammography is the most appropriate initial imaging modality for women 40 years and older who present with a breast mass, whereas ultrasonography is recommended for women younger than 30 years. […] Because of the imperfect sensitivity and specificity of CBE and imaging, patients should be referred for tissue sampling if suspicious findings are noted at any stage of the evaluation, regardless of benign findings at other stages. A highly suspicious breast mass found on CBE should be biopsied regardless of imaging findings, and suspicious masses on imaging should be biopsied even if the CBE suggested benign findings. […] In most cases, a core needle biopsy should be performed for evaluation of a suspicious mass. Compared with fine-needle aspiration, core needle biopsy has superior sensitivity, specificity, and ability to detect possible malignant invasion.

  Breast ultrasound is the first diagnostic step in patients of age who have clinical features concerning for malignancy. In patients 30 years of age whose mammography or DBT findings are normal, benign, or probably benign, a breast ultrasound should be performed for further evaluation. […] Biopsy (performed under image guidance when possible) is indicated in all patients with clinical or imaging features concerning for malignancy. […] Image-guided biopsies are usually preferred because they are less invasive than excisional biopsies and have similar accuracy. […] CNB has a higher sensitivity and specificity than FNA, can distinguish between noninvasive and invasive carcinomas, and allows for testing receptor status if needed.

• #38 Palpable breast lumps: An age-based approach to evaluation and diagnosis

  https://pmc.ncbi.nlm.nih.gov/articles/PMC9575372/

  A palpable breast lump is a common presentation of breast disease to a general practitioner. Fortunately, investigation of most of these lumps will lead to a benign diagnosis. It is essential to have a clear and systematic approach when investigating a palpable breast lump to avoid over investigation with the resultant increase in healthcare cost and anxiety. This article will discuss an approach to evaluating and diagnosing a palpable breast lump in the primary care setting. […] The risk of a breast lump representing a breast cancer increases with age, with a 1/204 (0.49%) chance of breast cancer for a woman in her thirties, compared with 1/28 (3.54%) chance for a woman in her sixties. […] With very few exceptions, every patient who presents with a breast lump needs to undergo a triple assessment. The triple assessment consists of a history and physical examination, some form of breast imaging and a biopsy. It is the gold standard in breast cancer diagnosis, with a positive predictive value of 100% if all three modalities are positive for breast cancer.

  The most reliable way to diagnose breast cancer is through a 'triple test’. If you find a change in your breast that could indicate breast cancer, or a mammogram shows something suspicious, your doctor should refer you to a breast specialist for further investigation using all three of these tests. The triple test is positive if the result of any component of it is suspicious, indeterminate or malignant (cancerous). If the result of any one test differs from the others then the diagnosis is uncertain and further investigation is required. Only when all three tests are negative (no evidence of cancer) can cancer be ruled out with 99% accuracy. […] Your doctor will examine your breasts for any signs of cancer, and talk to you about your medical and personal history. […] Mammogram, ultrasound and sometimes MRI are used to diagnose breast cancer.

  https://www.mayoclinic.org/diseases-conditions/suspicious-breast-lumps/diagnosis-treatment/drc-20562275

  Diagnosis of a breast lump involves getting an exam and possibly tests to find out the cause of the lump. During the physical exam, your healthcare professional checks your breasts, chest wall, underarms and neck. You’re checked while you’re sitting upright and again while lying on your back. […] You’ll likely need one or more imaging tests to check for changes in the breasts. These include: […] A diagnostic mammogram is different from a screening mammogram, which looks for breast cancer before a person has symptoms. […] If these tests show that your lump is not cancer, you might need follow-up appointments. That way, your healthcare professional can check to see if the lump grows, changes or goes away. […] If imaging tests don’t help diagnose the lump, your healthcare professional might take a sample of cells for lab testing. This is called a biopsy. […] Whichever type of biopsy you have, your healthcare professional sends the tissue samples to a lab to be checked by a pathologist. That’s a doctor who studies diseases and the changes they cause in body tissues.

• #46 Breast Biopsy: Procedure Types, What to Expect & Results Guide

  https://www.nationalbreastcancer.org/breast-cancer-biopsy/

  A breast biopsy is a test that removes tissue or sometimes fluid from the suspicious area. The removed cells are examined under a microscope and further tested to check for the presence of breast cancer. A biopsy is the only diagnostic procedure that can definitely determine if the suspicious area is cancerous. […] The good news is that 80% of women who have a breast biopsy do not have breast cancer. […] When mammogram results come back as abnormal or suspicious, a breast biopsy will likely be performed. […] Core-needle and surgical biopsies are most commonly used on the breast. […] There are several factors that help a doctor decide which type of biopsy to recommend. These include the appearance, size, and location of the suspicious area on the breast. […] Once the biopsy is complete, a specially trained doctor called a pathologist examines the tissue or fluid samples under a microscope, looking for abnormal or cancerous cells. The pathology report, which can take one or two weeks to complete, is sent to the patient’s doctor. It indicates whether the suspicious area is cancerous and provides a full picture of your situation.

  Both invasive ductal carcinomas and invasive lobular carcinomas start in the cells lining the ducts and lobules in the breast. In general, invasive lobular and invasive ductal carcinomas of the breast aren’t treated differently. […] Since some breast cancers are made up of more than one type, the entire tumor must be removed (by lumpectomy or mastectomy) in order to know what types your tumor contains. A needle biopsy doesn’t give enough information to guide treatment. […] If cancer cells are seen in small blood vessels or lymph vessels (lymphatics) within the tumor, it is called vascular, angiolymphatic, or lymphovascular invasion.

  The stage of a breast cancer is based on the size of the tumor and if the cancer has spread, as well as certain other characteristics such as the tumor grade, estrogen receptor (ER) and progesterone receptor (PR) status, and HER2 status. […] If breast cancer spreads, it often goes first to the nearby lymph nodes under the arm (axillary lymph nodes). […] An important step in evaluating breast cancer is to test cancer cells removed during the biopsy (or surgery) to see if they have estrogen and progesterone receptors. […] Results for ER and PR are reported separately, and they might be reported in different ways. […] Some breast cancers have too much of a protein called HER2/neu, which helps them grow.

The risk of a breast lump being malignant in adolescence is exceedingly rare. […] It is advisable that a breast MRI should only be requested by a specialist. In women under 35 years, breast ultrasound would be the imaging modality of choice. An ultrasound examination can focus on the palpable lump to obtain more information to aid the diagnosis.

  Although CBE has poor predictive value for determining whether a breast mass is cancerous, some features of breast masses may help distinguish between benign and malignant lesions. […] The sensitivity of CBE ranges from 49% to 69%, and specificity is 86% to 99%. Detection of malignancy increases when imaging is added to the evaluation. […] Diagnostic mammography is the most appropriate initial imaging modality for women 40 years and older who present with a breast mass, whereas ultrasonography is recommended for women younger than 30 years. […] Because of the imperfect sensitivity and specificity of CBE and imaging, patients should be referred for tissue sampling if suspicious findings are noted at any stage of the evaluation, regardless of benign findings at other stages. A highly suspicious breast mass found on CBE should be biopsied regardless of imaging findings, and suspicious masses on imaging should be biopsied even if the CBE suggested benign findings. […] In most cases, a core needle biopsy should be performed for evaluation of a suspicious mass. Compared with fine-needle aspiration, core needle biopsy has superior sensitivity, specificity, and ability to detect possible malignant invasion.

  A systematic examination of the breast must be undertaken. […] Radiological assessment of the breast is essential and commonly consists of either an ultrasound, mammogram or both. […] The current gold standard in diagnosing breast lumps is a core needle biopsy. It provides histology for an accurate diagnosis and allows immunohistochemistry (IHC) to be performed. […] Therefore, age has been proposed to guide investigations in the work-up of breast lumps. […] With an increase in age, the risk of breast cancer increases. Therefore, it is recommended that all women over 25 undergo a full triple assessment. […] An age-based approach to breast lumps allows for a cost-effective, safe and systematic pathway to investigate and treat breast lumps.

  https://www.lbbc.org/about-breast-cancer/testing/can-diagnosis-be-wrong

  It is unusual, but possible, for breast cancer tests and even a breast cancer diagnosis to be inaccurate. Before breast cancer is diagnosed, a person typically has screening mammography and other diagnostic tests. These may show abnormal results or suspicious tissue that do not always turn out to be breast cancer. It is also possible for a screening test alone, without further study, to miss suspicious tissue or other signs you may have breast cancer. […] It is less common for a breast cancer diagnosis to be incorrect. No test is perfect. It is possible that an expert has looked at tissue taken from a biopsy and said you had cancer when you do not or has said you do not have cancer when you do. In the United States, there are currently no standards in place to track how often that happens. Different sources say that a very small percentage of U.S. breast cancer diagnoses could be incorrect. Fortunately, there are things you can do to be more certain in your diagnosis and test results.

  However, even if the mammogram or ultrasound is reported as benign, the standard of care requires that the physician further investigate a solid, persistent, and dominant mass by fine needle or tissue biopsy. […] Relying on a negative mammogram to rule out cancer in a woman with a clinically suspicious breast mass is unacceptable. […] False negative results from mammography in women with palpable breast masses have been reported to be as high as twenty-two percent (22%). […] Some of the features which raise the index of suspicion for breast cancer include a mass which has a hard or gritty texture, is fixed or immobile, has irregular borders, and does not vary in size during the menstrual cycle. […] In conjunction with other organizations, the American College of Radiologists has developed a uniform system for classifying and reporting the level of suspicion for breast cancer on mammography or ultrasound, and what action, if any, should be taken in follow-up.

  It is important to remember that even if your doctor tells you that a biopsy is needed, most women who do it do not have breast cancer. In the US, about 1 in 10 women who have biopsies are diagnosed with cancer. […] Given the accuracy and ease of needle biopsy, many women undergo this procedure first. A surgical biopsy would only be necessary if the results of a needle biopsy are in question. […] A surgical biopsy is the most accurate biopsy method that is able to provide complete information about tumors. […] Even a biopsy may not be 100 percent accurate. Research has shown that the false-negative rate for core biopsy, a type of needle biopsy, can be as high as 8 percent. […] In the case of fine needle aspiration, the evaluation may potentially be inaccurate because the tissue sample taken is very small. When used alone, up to about 10% of breast cancers may be missed. Consequently, when a fine needle aspiration does not find cancer, it may still need to be followed up with another type of biopsy, such as a core needle or surgical biopsy.

• #85 Breast Lump: Types, Causes, How to Check Them & Treatment

  https://www.nationalbreastcancer.org/breast-lump/

  All breast lumps, no matter the size or texture, should be checked by a healthcare professional. […] Although breast lumps are common and many are non-cancerous, there are several breast lump warning signs to be aware of. See your healthcare professional if you notice: A new lump, thickening, or swelling of the breast tissue not previously noticed by you or your doctor; A lump that feels hard to the touch or different from the rest of the breast tissue; A known lump that begins to grow or change; A lump that does not go away after menstruation; A lump that causes pain or discomfort. […] While some breast cancers may produce a noticeable lump or other symptoms, it is important to remember that in its early stages, breast cancer does not produce any noticeable symptoms or signs. This is why practicing early detection methods, such as receiving annual mammograms, annual well-woman visits that include clinical exams, and monthly breast self-exams are critical to diagnosing breast cancer early, when it is most treatable.
