Benign breast disease and oral contraceptive use

A random selection of 1,230 upstate New York childbearing women was used to examine the history of oral contraceptive use in women with a clinical diagnosis of benign breast disease. We found that 73 women who had benign breast disease had a reduced duration of pill use. When determining the reason for this reduction, we found that in a significant portion (P less than .05) of our benign breast disease cases, the women had been advised by their physicians to discontinue pill use for breast-related reasons. We then surveyed a large group of upstate New York physicians. One third of them considered benign breast disease a potential contraindication for starting oral contraceptive use. Nearly one half throught the development of benign breast disease to be a potential contraindication for continuing oral contraceptive use. It is premature to conclude that oral contraceptive usage protects against benign breast disease.
