Screening is done to find a health problem early and treat it. Tests are usually given to people who do not have symptoms but who may be at high risk for the health problem.
Ask your doctor when you should be screened and how often. Screening guidelines differ and can be confusing. The goal is to have women to their doctor about these tests.
The chart below is from the United States Preventive Services Task Force (USPSTF), the American Cancer Society, and the American College of Obstetricians and Gynecologists (ACOG).
|Mammogram||Clinical Breast Exam||Breast Self-exam|
Age 50 to 74: Mammogram every 2 years.
Age 40 to 49: Shared decision with doctor to have a mammogram every 2 years.
Age 75 and older: No recommendation given.
|No recommendation given.||Not recommended, but encourage breast self-awareness.|
|American Cancer Society|
Age 40 to 44: Women can start screening if that is their choice. Start talking about screening tests with your doctor.
Age 45 to 54: Every year.
Age 55 and older: Switch to every 2 years, and continue if 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.
|No recommendation given.||No recommendation given, but encourage breast self-awareness.|
Age 40 to 49: Shared decision with doctor to have a mammogram every 1 to 2 years.
Age 50 to 75 years: Every 1 to 2 years.
Age older than 75 years: Shared decision with doctor to continue with mammograms.
Age 25 to 39: Every 1 to 3 years.
Age 40 and older: Every year.
|Not recommended, but encourage breast self-awareness.|
All women should be aware of changes in their breasts, no matter what age. This includes 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 breast cancer is not the reason for all breast changes. Talk to your doctor about any changes you notice.
If you are at high risk for breast cancer, screening tests may be done more often or 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 USPSTF recommends:
ACOG recommends that high-risk women consider doing regular breast self-exams.
There are 3 main tests. Choose which ones you want to do after you talk it over with your doctor. Each one has risks, harms, and benefits:
