Abstract

Annual screening mammography beginning at age 40 is recommended for the general population. For some women at high risk for developing breast cancer at a younger age, annual screening may be appropriate starting at an earlier age. These women include those with a personal history of breast cancer, nontherapeutic radiation to the breasts especially for Hodgkin's disease, BRCA positive women, women with a family history of a first-degree relative with breast cancer at a young age, and women with a biopsy diagnosis of lobular carcinoma in situ or atypical ductal hyperplasia. Women with a biopsy diagnosis of atypical lobular hyperplasia develop breast cancer after age 40 and do not need earlier screening, unless they have a family history of breast cancer. Although increasing a woman's risk for breast cancer, radial scar does not increase risk for women younger than 40 years old and therefore does not require screening at a young age.
