Early detection, through the use of screening methods, helps find cancers early when they are most treatable.Discuss with your doctor concerns you may have around breast cancer screening -- and share if you have a family history of cancer -- so you can decide when it is best for you to begin.
Screening methods to find breast cancer include clinical breast examination (doctors or nurses examine women's breasts for lumps), mammography, and other imaging techniques.
American Cancer Society Breast Cancer Screening Guidelines
- Women age 40 and older should have a screening mammogram every year and should continue to do so for as long as they are in good health.
- Women in their 20's and 30's should have a clinical breast exam (CBE) as part of a periodic (regular) health exam by a health professional, at least every 3 years. After age 40, women should have a breast exam by a health professional every year.
- Breast self exam (BSE) is an option for women starting in their 20's. Women should be told about the benefits and limitations of BSE. Women should report any breast changes to their health professional right away.

Mammograms are x-ray pictures of the breast that are effective for finding breast cancer. Mammograms can be used to check for breast cancer in women who have no signs or symptoms of the disease. This type of mammogram is called a screening mammogram. Mammograms also can be used to check for breast cancer after a lump or other sign or symptom of the disease has been found. This type of mammogram is called a diagnostic mammogram.
Clinical Breast Exam
An exam of the breast by a doctor or other health professional. The doctor will carefully feel the breasts and under the arms for lumps or anything else that seems unusual.
