While most studies have found no association between oral contraceptive use and breast cancer, several studies of younger women have reported an association with long-term oral contraceptive use.
We studied the relationship of patterns of oral contraceptive use to breast cancer risk among younger women.
These women have had oral contraceptives available their entire reproductive lives and are now entering the breast cancer-prone years.
A population-based, case-control study of breast cancer was conducted in three counties in western Washington State among women born in 1945 or later, ages 21-45.
Case patients were 747 women with breast cancer diagnosed in 1983-1990 and identified through the Seattle-Puget Sound Surveillance, Epidemiology, and End Results cancer registry.
