Lifetime menstrual activity : indicator of breast cancer risk.
A case-control study of 67 cases of breast cancer and 157 controls was conducted to investigate the role of different behavioral, reproductive, and hormonal factors and to develop a unifying indicator of breast cancer risk.
The results confirm previous reports of the influence of smoking on the risk of breast cancer.
Age at menarche was found to be a risk factor among the premenopausal women.
Late age at menopause was suggestive of an increase in risk.
Long use of oral contraceptive or estrogen supplementation were risk-enhancing both pre- and postmenopausally.
