Lifestyle Factors That Impact Breast Cancer Risk

Alcohol: Drinking Alcohol Increases Risk of Breast Cancer

Weight and Body Composition: Excess body fat increases risk for post-menopausal breast cancer. Lean muscle, low body fat decreases risk of pre-menopausal breast cancers

Physical Activity: Sedentary behaviour is linked to increased risk of breast cancer, while being active decreases the risk of breast cancer.

Vigorous activity decreases the risk for pre-menopausal breast cancer.

Moderate activity decreases risk for post-menopausal breast cancer.

Some evidence indicates that people who are physically active (both before and after diagnosis) have a greater chance of surviving breast cancer.

Breastfeeding: Reduces risk of both pre- and post-menopausal breast cancer.

Sleep: Women who report sleeping less than 5 hours per night before diagnosis have an increased risk of dying from breast cancer compared to women whose pre-diagnosis sleep pattern was 7-8 hours per night. Women who have disrupted circadian rhythms due to night shift work have an increased risk of breast cancer.
