Estrogen Therapy and the Risk of Breast, Ovarian, and Endometrial Cancer
Millions of women have used estrogens for relief of menopausal symptoms. Theoretical considerations, clinical observations, and epidemiologic information raise concern as to possible associations between use of exogenous estrogens and cancers of the female reproductive tract (Thomas, 1978). Because of the large number of women who have been using or will use estrogens for menopausal symptoms, any risk of or protection from these cancers could have major health impact on women in their postmenopausal years.
