Study finds early BPA exposure increases prostate cancer risk
The researchers found that human prostate stem cells implanted into mice were far more susceptible to cancer if BPA was included in the animal's diet.
Researchers at the University of Illinois at Chicago released study results they say demonstrate an increased risk of prostate cancer among those exposed to BPA at an early age. Professor of physiology Gail Prins implanted mice with healthy human stem cells before feeding some mice BPA at levels consistent with a pregnant woman's consumption for two weeks. When prostate carcinogenesis was initiated, a third of the mice that had been fed BPA demonstrated precancerous tissues compared to 13 percent in a control group. Prins says while she doesn't have evidence that BPA is causing the cancer, she thinks it is reprogramming stem cells and leading to heightened susceptibility to cancer later on.
