We don't know how to prevent breast cancer, but we do know
good lifestyle habits help to
reduce your risk. Approximately 38% to 42% of breast cancers in countries like Canada are linked to lifestyle-related risk factors. Unfortunately, there are some risk factors that you can’t control, including:
- Breast density
- A family history of breast cancer (only 5% to 10% of women who develop breast cancer have a genetic risk)
- If you are post-menopausal
- If you started your period before age 12
- If you started menopause after age 55
- If you never had a baby or had your first baby after age 30
- If you have never breastfed
