- personal or family history of breast cancer
- certain breast changes found on biopsy
- certain genetic changes
- menstrual periods before age 12 or menopause after age 55
- having a first child after age 30 or never having a child
- long-term use (more than 5 years) of menopausal hormone therapy
- dense breast tissue
- radiation therapy to the chest before age 30
- alcohol use
- having taken the drug diethylstilbestrol (DES) during pregnancy
