Could some women who naturally produce excess aromatase in their breasts have an increased risk of developing breast cancer? Investigators say their mice study shows that overproduction of aromatase, which converts testosterone into estrogen, in breast tissue is even more important in pushing breast cancer development than excess production of the estrogen receptor that the hormone uses to activate mammary cells.
