- Being older at the birth of your first child.
- Never giving birth
- Not breastfeeding.
- Personal history of breast cancer or some non-cancerous breast diseases.
- Family history of breast cancer (mother, sister, daughter).
- Treatment with radiation therapy to the breast/chest.
- Being overweight (increases risk for breast cancer after menopause).
- Long-term use of hormone replacement therapy (estrogen and progesterone combined).
- Having changes in the breast cancer-related genes BRCA1 or BRCA2.
