Abstract
Age, age at menopause, and calendar year at menopause were controlled as factors related to estrogen use. Data on 90 breast cancer patients and 83 conrols--all of whom had a natural menopause--showed no relationship between breast cancer and estrogen usage after the start of menopause symptoms.Entities:
