Risk Factors for Breast Cancer

There are various risk factors connected with breast cancer, including increasing age and hormonal factors, especially the determinants of menstrual life and childbirth history. Breast cancer in close family members (first degree relatives) increases risk.

Other factors associated with increased risk are a previous history of breast cancer or benign disease, an increased body size, especially a heavier body weight at older ages and exposure of breast tissue to ionizing radiation (particularly before 20 years of age).
Research is still continuing in many areas.
