  Breast cancer is one of the leading causes of cancer-related morbidity and mortality in women worldwide. Early diagnosis and effective treatment of all types of cancers are crucial for a positive prognosis. Patients with small tumor sizes at the time of their diagnosis have a significantly higher survival rate and a significantly reduced probability of the cancer being fatal. Therefore, many novel technologies are being developed for early detection of primary tumors, as well as distant metastases and recurrent disease, for effective breast cancer management. […] Early diagnosis of the disease is crucial for effective treatment and positive prognosis, as significantly lower probability of dying and higher survival rate is observed in patients with smaller tumors at the time of diagnosis. Early detection of breast cancer and accurate lesion assessment are, therefore, the primary focus of all imaging modalities. At present the two major pillars to be addressed for effective management of breast cancer disease include: (i) diagnosis of breast cancer in its earliest stages and (ii) providing timely treatment after diagnosis to save lives.

  https://my.clevelandclinic.org/health/diseases/3986-breast-cancer

  Breast cancer is one of the most common cancers that affects women. It happens when cancerous cells in your breasts multiply and become tumors. About 80% of breast cancer cases are invasive, meaning a tumor may spread from your breast to other areas of your body. […] Healthcare providers may do physical examinations or order mammograms to check for signs of breast cancer. But they do the following tests to diagnose the disease: Breast ultrasound, Breast magnetic resonance imaging (MRI) scan, Breast biopsy, Immunohistochemistry test to check for hormone receptors, Genetic tests to identify mutations that cause breast cancer. […] Healthcare providers use cancer staging systems to plan treatment. Staging cancer also helps providers set a prognosis, or what you can expect after treatment. Breast cancer staging depends on factors like breast cancer type, tumor size and location, and whether cancer has spread to other areas of your body. Breast cancer stages are: Stage 0: The disease is noninvasive, meaning it hasnt spread from your breast ducts to other parts of your breast. Stage I: There are cancerous cells in nearby breast tissue. Stage II: The cancerous cells have formed a tumor or tumors. The tumor is either smaller than 2 centimeters across and has spread to underarm lymph nodes or larger than 5 centimeters across but hasnt spread to underarm lymph nodes. Tumors at this stage can measure anywhere between 2 and 5 centimeters across, and may or may not affect the nearby lymph nodes. Stage III: Theres breast cancer in nearby tissue and lymph nodes. Stage III is usually referred to as locally advanced breast cancer. Stage IV: Cancer has spread from your breast to areas like your bones, liver, lungs or brain. […] The most significant complication is metastatic breast cancer breast cancer that spreads to other areas of your body, including your brain, bones, liver and lungs. Studies show about 1 in 3 women who have early-stage cancer later develop metastatic breast cancer.

  https://www.aafp.org/pubs/afp/issues/2000/0801/p596.html

  Mammographic screening is appropriate for asymptomatic women. Diagnostic mammography, which may include additional views, is done for women with signs or symptoms of breast cancer. Any sign of cancer should be communicated to the radiologist with the referral for a diagnostic mammogram. […] The American Cancer Society (ACS) and the National Cancer Institute recommend screening mammograms every year for asymptomatic women 40 years and older. […] Regular screening mammography along with regular clinical breast examination offer the best opportunity to increase this percentage. […] Women between the ages of 40 and 69 have a 30 percent chance of a false-positive screening mammogram or breast examination over a 10-year period. […] It is extremely important to remember that 10 to 15 percent of all breast cancers are not detected by a mammogram. A careful clinical breast examination is also necessary. A palpable breast mass that is not seen on a mammogram should have a thorough diagnostic work-up including ultrasound and needle biopsy and close follow-up.

• #8 Detection & Diagnosis of Breast Cancer | WVCI

  https://www.oregoncancer.com/breast-cancer/detection-diagnosis

  An important step women can take to protect their health is to get a mammogram. It is the American Cancer Society’s primary recommended breast cancer screening method. Because there are no symptoms of breast cancer at its earliest stages, this screening test saves lives. […] A mammogram is an X-ray picture of tissue inside the breast. It can often show a breast lump before it can be felt. They can also display a cluster of calcium specks called microcalcifications. Lumps or specks can be from cancer, precancerous cells, or other conditions. Further testing is needed to find out whether cancer cells are present. […] Women should get regular screening mammograms to detect breast cancer early even before they have symptoms. […] If the mammogram shows an abnormal area of the breast, your doctor may order more detailed images. Doctors use diagnostic mammograms to learn more about unusual breast changes, such as a lump, pain, thickening, nipple discharge, or change in breast size or shape. Diagnostic mammograms may focus on a specific area of the breast, offering more detailed views than traditional screening mammograms.

• #9 Breast Cancer Screening – NCI

  https://www.cancer.gov/types/breast/patient/breast-screening-pdq

  Screening is looking for signs of disease, such as breast cancer, before a person has symptoms. The goal of screening tests is to find cancer at an early stage when it can be treated and may be cured. […] If a screening test result is abnormal, you may need to have more tests done to find out if you have cancer. These are called diagnostic tests, rather than screening tests. […] Mammography is the most common screening test for breast cancer. […] Mammography is an imaging test used to screen for and diagnose breast cancer. It can detect abnormal breast tissue, including cancer, sometimes before symptoms appear. […] Women aged 50 to 69 years who have screening mammograms have a lower chance of dying from breast cancer than women who do not have screening mammograms. […] MRI may be used as a screening test for women who have a high risk of breast cancer.

• #10 Recommendation: Breast Cancer: Screening | United States Preventive Services Taskforce

  https://www.uspreventiveservicestaskforce.org/uspstf/recommendation/breast-cancer-screening

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

  Breast cancer can be diagnosed through multiple tests, including a mammogram, ultrasound, MRI, and biopsy. […] Regular screenings, including breast self-exams, mammograms, and clinical breast exams, can help detect cancer before signs or symptoms develop. […] A diagnostic mammogram is used if signs of breast cancer are present or after suspicious results are found on a screening mammogram. […] An ultrasound (or sonogram) may be used to help determine if a breast lump is a benign cyst or a solid mass that may indicate breast cancer. […] A breast MRI uses magnetic energy and radio waves to assess the size and specific location of an abnormal finding in the breast tissue. […] A biopsy removes tissue or fluid from a suspicious area in the breast tissue that is then examined to check for the presence of breast cancer. […] Lab tests, such as a hormone receptor test and HER2/neu test, are used to determine prognosis and treatment options after a breast cancer diagnosis.

  Breast specific gamma imaging (BSGI), a molecular breast imaging approach, is a specialized nuclear medicine imaging test that allows detection of sub-centimeter and mammographically occult breast cancer with a sensitivity and specificity comparable to MRI. […] Although mammography is a gold standard for breast cancer imaging, because of its limitations regarding dense breasts, another supplementing screening tool is required. Ultrasound is a supplemental tool that may be utilized to analyze some breast changes in women with dense breast tissues, as well as suspicious areas not seen on a mammogram. […] Breast cancer diagnosis by breast examination, mammography, breast ultrasound, MRI, and other imaging modalities can help identify tumors and other abnormalities in the tissue, as described above. These imaging modalities can help find a lump, an area of microcalcification, a suspicious area on ultrasound, or a gadolinium-enhanced area on MRI. Once breast cancer is identified using one of the diagnostic modalities discussed above, immediate and rigorous treatment must be provided to remove the tumor and prevent further spread of the cancer.

• #13 Breast Cancer Workup: Approach Considerations, Breast Cancer Screening, Ultrasonography

  https://emedicine.medscape.com/article/1947145-workup

  A number of screening modalities exist for breast cancer, including mammography, ultrasonography, and MRI. Breast self-examination is no longer recommended for screening. Instead, breast awareness is recommended; women should be familiar with how their breasts normally look and feel, and report any changes promptly to their health care provider. Most guidelines also recommend against clinical breast examination. […] Mammography is a low-dose x-ray-based modality used to image the breast. It is currently the best available population-based method for detecting breast cancer at an early stage. Mammography is used both for screening to detect a cancer and for diagnostic workup of patients after a tumor is detected. Screening mammography is performed in asymptomatic women, whereas diagnostic mammography is performed in symptomatic women (ie, when a breast lump or nipple discharge is present or when an abnormality is found during screening mammography).

  A biopsy is where a sample of tissue cells is taken from your breast and tested to see if it’s cancerous. You may also need a scan and a needle test on lymph nodes in your armpit (axilla) to see whether these are also affected. […] If you have symptoms and have been referred by your GP, you’ll meet a specialist who’ll examine you to determine if you need further tests. […] If you’re under 40 years of age, the specialist may suggest you only have a breast ultrasound scan. This is because younger women have denser breasts, which means a mammogram isn’t as effective as an ultrasound for diagnosing breast disease. […] If your cancer was detected through the NHS Breast Screening Programme, you’ll have further tests in the screening centre before being referred for treatment.

  Clinical breast exams (physical exams done by a health professional) are not recommended for breast cancer screening among average-risk women at any age. […] Regular mammograms can help find breast cancer at an early stage, when treatment is most likely to be successful. A mammogram can often find breast changes that could be cancer years before physical symptoms develop. […] Results from many decades of research clearly show that women who have regular mammograms are more likely to have breast cancer found earlier, are less likely to need aggressive treatments like surgery to remove the entire breast (mastectomy) and chemotherapy, and are more likely to be cured. […] The American Cancer Society recommends against MRI screening for women whose lifetime risk of breast cancer is less than 15%.

  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.

[…] Ultrasonographic screening is useful to differentiate between solid and cystic breast masses when a palpable mass is not well seen on a mammogram. […] The three breast biopsy techniques in current use are applicable to different diagnostic situations. Fine-needle aspiration (FNA) biopsy generally uses a 20-gauge needle to obtain samples from a solid mass for cytology. […] A clinically suspicious mass should be followed even if mammographic findings are normal. Lumpectomy should be done for suspicious masses and should include a 1-cm margin of normal tissue. FNA biopsy may be used as the initial diagnostic test. […] A patient with bilateral, milky nipple discharge should be evaluated for prolactinoma. Cytology of the discharge is rarely helpful. A mammogram should be obtained for a suspicious discharge even though results are usually negative.

  Breast cancer. It’s the diagnosis virtually all women fear, and understandably so. Breast cancer strikes one of every eight women in this country and almost everyone knows someone who has been diagnosed with this disease. […] However, with early diagnosis and advances in treatment, breast cancer can be treated successfully and, in many cases, cured. […] During the lumpectomy or mastectomy, some of the lymph nodes in the armpit will likely be removed to determine if the cancer has spread (lymph nodes in the underarm are the first place breast cancer spreads). […] For early breast cancers, sentinel lymph node biopsy is a technique in which the lymph nodes that first drain the breast are identified and sampled. If cancer is not found in the „sentinel” nodes, no additional lymph nodes need to be removed. This has the advantage of faster recovery and less risk of lymphedema (swelling of the arm).

This information helps doctors develop a customized treatment plan for you. […] The imaging tests used for breast cancer screening, including traditional and three-dimensional mammograms, ultrasound, and MRI, may also be used during diagnosis. If doctors identify a suspicious growth, they may recommend that a woman have a biopsy, the removal of breast tissue, so it can be examined for signs of cancer. […] After any type of biopsy, our pathologists examine tumor tissue under a microscope to determine if breast cancer is present and, if so, the type. They can also evaluate the lymph nodes to see if the cancer has spread beyond the breast. […] Pathologists test tumor tissue for hormonal and genetic features that can help guide treatment decisions. […] The female hormones estrogen and progesterone can contribute to the growth of breast cancer. In some women, breast cancer cells have receptors, or proteins, on their surface that attach to estrogen, progesterone, or both. Breast cancers that test positive for these receptors rely on these hormones to grow. […] Pathologists can also determine whether a tumor is positive for HER2, a protein that encourages cells to grow. […] If pathologists find that the tumor tissue is not positive for estrogen receptors, progesterone receptors, or HER2, the cancer is referred to as triple negative.

  Breast cancer is one of the most common cancers that affects women. It happens when cancerous cells in your breasts multiply and become tumors. About 80% of breast cancer cases are invasive, meaning a tumor may spread from your breast to other areas of your body. […] Healthcare providers may do physical examinations or order mammograms to check for signs of breast cancer. But they do the following tests to diagnose the disease: Breast ultrasound, Breast magnetic resonance imaging (MRI) scan, Breast biopsy, Immunohistochemistry test to check for hormone receptors, Genetic tests to identify mutations that cause breast cancer. […] Healthcare providers use cancer staging systems to plan treatment. Staging cancer also helps providers set a prognosis, or what you can expect after treatment. Breast cancer staging depends on factors like breast cancer type, tumor size and location, and whether cancer has spread to other areas of your body. Breast cancer stages are: Stage 0: The disease is noninvasive, meaning it hasnt spread from your breast ducts to other parts of your breast. Stage I: There are cancerous cells in nearby breast tissue. Stage II: The cancerous cells have formed a tumor or tumors. The tumor is either smaller than 2 centimeters across and has spread to underarm lymph nodes or larger than 5 centimeters across but hasnt spread to underarm lymph nodes. Tumors at this stage can measure anywhere between 2 and 5 centimeters across, and may or may not affect the nearby lymph nodes. Stage III: Theres breast cancer in nearby tissue and lymph nodes. Stage III is usually referred to as locally advanced breast cancer. Stage IV: Cancer has spread from your breast to areas like your bones, liver, lungs or brain.
