Breast cancer cannot be completely prevented, but adopting healthy lifestyle choices and risk-reducing strategies can significantly lower your risk.

Understanding Risk Factors. Some factors that increase breast cancer risk are beyond your control, such as genetics, family history, age, race, and breast density. However, research shows that 30 to 70 percent of breast cancers may be preventable through modifiable behaviours, depending on when these changes are adopted. This means that while no method guarantees prevention, risk can be meaningfully reduced. Several evidence-based lifestyle modifications can help reduce breast cancer risk

Excess body weight, especially after menopause, is linked to higher breast cancer risk.

Regular exercise helps regulate hormones and maintain a healthy weight. Adults should aim for at least 150–300 minutes of moderate-intensity or 75–150 minutes of vigorous-intensity activity weekly.

Alcohol increases breast cancer risk, so moderation or abstinence is recommended.

 Diets rich in fruits, vegetables, and whole grains may contribute to overall cancer risk reduction.

Tobacco use is linked to many cancers, including breast cancer.

Breastfeeding for several months can provide a small protective effect.
