Breast Cancer Screening Recommendations

The United States Preventive Services Task Force (USPSTF) is an organization made up of doctors and disease experts who research the best way to prevent diseases and make recommendations on how doctors can help patients avoid diseases or find them early. The United States Preventive Services Task Force (USPSTF) recommends that women 50 to 74 years old and at average risk for Breast Cancer get a mammogram every two years. Women 40 to 49 years old should talk to their doctor or other health care professional about when to start and how often to get a mammogram ​2​. Women should weigh the benefits and risks of screening tests when deciding whether to begin getting mammograms before age 50.

What are the available Breast Cancer Screening Tests

Mammogram

A mammogram is an X-Ray of the breast. Mammograms are the best way to find Breast Cancer early when it is easier to treat and before it is big enough to feel or cause symptoms. Having regular mammograms can lower the risk of dying from Breast Cancer. At this time, a mammogram is the best way to find Breast Cancer for most women.

Breast Magnetic Resonance Imaging (MRI)

A breast MRI uses magnets and radio waves to take pictures of the breast. MRI is used along with mammograms to screen women at high risk of getting Breast Cancer. Because breast MRIs may appear abnormal even when there is no cancer, they are not used for women at average risk.

Clinical Breast Exam

A clinical breast exam is an examination by a doctor or nurse who uses their hands to feel for lumps or other changes.

It can lead to more tests, which can be expensive, invasive, time-consuming, and may cause Anxiety. Tests also can lead to over diagnosis when doctors find cancer that would not have gone on to cause symptoms or problems or even may go away on its own. Treatment of these cancers is called overtreatment. Overtreatment can include treatments recommended for breast cancer, such as Surgery or Radiation therapy. These can cause unnecessary and unwanted side effects.
Other potential harms from Breast Cancer screening include Pain during the procedure and radiation exposure from the mammogram test. While the amount of radiation in a mammogram is small, there may be risks with having repeated X-rays. Mammograms may also miss some false-negative test results, delaying finding cancer and getting treatment.

What is an endoscopy?

An Endoscopy is a procedure where the surgeon uses specialized instruments to examine and operate on the body’s internal organs and vessels. It helps doctors to see issues inside the body without making large incisions. A surgeon inserts an endoscope through a small cut or a natural opening in the body. An endoscope is a flexible tube with a camera attached to it that lets your doctor see. Your doctor can control forceps and scissors at the end of the endoscope to perform Biopsy operations.
