Screening Guidelines

A. Breast Self-Examination. All women older than age 20 years should perform regular monthly breast self-examinations. Menstruating women should examine their breasts in the first 7 to 10 days of the menstrual cycle.

Women aged 50 to 69 years should be offered mammogra-phy and receive a clinical breast examination every 1 to 2 years.

B. Clinical Breast Examination (CBE) is recommended every 1 to 3 years for women aged 30 to 39 years and annually for those aged 40 years and older.

C. Mammography alone is 75% sensitive, and, when combined with CBE, the screening sensitivity for detecting breast cancer increases to 88%. Screening guidelines from the US Preventive Services Task Force suggest mammography alone or with CBE every 1 to 2 years for women aged 50 to 69 years. Recent evidence suggests a benefit from annual mammography with or without CBE for women aged 40 to 49 years.
