Being physically active, maintaining a healthy weight, and practicing mindfulness-based stress reduction can help modify breast cancer risk. Pregnancy and breastfeeding can lower your risk, as can limiting exposure to estrogen therapy and hormone replacement therapy. Having a child before age 30 and breastfeeding for at least six months can also reduce risk. At the Texas Breast Center, we provide comprehensive advice and support to help you understand and manage all known risk factors for breast cancer.
