Breast Cancer

NPR's Joanne Silberner reports on a new study showing that some women who are already at risk of breast cancer may have inadvertently increased that risk if they took birth control pills before 1975. Those pills had a higher level of the hormone estrogen than pills made later. The study looked at women who have already had a sister or mother with breast cancer.
