Benign breast tumor and estrogenic hormones: a population-based retrospective study.
Histories of the usage of oral contraceptives and other estrogens were obtained from 320 women 20-49 years of age who had pathologically confirmed diagnoses of benign breast disease made at Washington County Hospital in Hagerstown, Maryland, during the period 1968 through 1972. Similar histories were obtained from 320 controls matched for race, sex, age, residence in county, and willingness to participate in a health survey. No association could be found between oral contraceptive usage and benign breast tumor. The use of other estrogens, notably diethylstilbestrol, was significantly related to the presence of benign breast disease.
