Breast Cancer Risk Assessment and Screening in Average-Risk Women

Women at average risk of breast cancer should be offered screening mammography starting at age 40 years. Women at average risk of breast cancer should initiate screening mammography no earlier than age 40 years. If they have not initiated screening in their 40s, they should begin screening mammography by no later than age 50 years. The decision about the age to begin mammography screening should be made through a shared decision- making process. This discussion should include information about the potential benefits and harms.
