The purpose of screening is early diagnosis and treatment. Screening tests are administered to people without current symptoms, but who may be at average or high risk for certain diseases or conditions.
Several professional organizations have published sometimes differing guidelines for breast cancer screening. Though this may seem confusing, the ultimate goal is to encourage individuals to discuss the risks, harms, and benefits of different breast cancer screening tests with their doctor.
The most current guidelines below are from the United States Preventive Services Task Force, the American Cancer Society, and the American Congress of Obstetricians and Gynecologists.
|Mammogram||Clinical Breast Exam||Breast Self-exam|
|United States Preventive Services Task Force||
Age 40-49: Shared decision with doctor to have a mammogram every 2 years until age 50.
Age 50 and older: Every 2 years until age 74.
Age 75 and older: No recommendation given.
|No recommendation given.||Against teaching women how to do breast self-exam.|
|American Cancer Society||
Age 40-44: Women can start screening if that is their choice. Start talking about screening tests with your doctor.
Age 45-54: Every year.
Age 55 and older: Start transitioning to every 2 years, and continue as long as overall health is good and life expectancy is 10 years or more. A mammogram every year can be done for women who choose to do so.
|Not recommended.||Not recommended.|
|American Congress of Obstetricians and Gynecologists||
Age 40 and older: Every year.
Age 20-39: Every 1-3 years.
Age 40 and older: Every year.
|Encourage breast self-awareness.
Information given on self-exam for women who choose to do so.
Breast self-awareness is very important at any stage of life. Be aware of any changes, such as new or disappearing lumps, clear or bloody nipple discharge, dimpling or thickening of the skin, pain, or a feeling of fullness in the underarm area. Not all breast cancers cause symptoms and not all breast changes are caused by cancer, but it is important to discuss these with your doctor so they can determine if further testing is needed.
If you are in a high-risk group for developing breast cancer, you and your doctor will schedule more frequent screening tests, which will start at an earlier age.
The American Cancer Society recommends a yearly mammogram with an MRI scan starting at age 30 years for women with:
The United States Preventive Services Task Force recommends:
The American Congress of Obstetricians and Gynecologists recommends that high-risk women consider doing regular breast self-exams.
There are 3 main tests to screen women for breast cancer. Not all organizations recommend these methods, but you may choose to do them after you discuss the risks, harms, and benefits with your doctor. These include:
MRI scans may be used to screen high-risk women.
