Chemical in Plastics Is Tied to Prostate Cancer
Bisphenol A, found in baby bottles and microwave cookware, permanently altered genes in newborn lab rats, a study finds.

Linking prostate cancer to a widespread industrial compound, scientists have found that exposure to a chemical that leaks from plastic causes genetic changes in animals' developing prostate glands that are precursors of the most common form of cancer in males.
The chemical, bisphenol A, or BPA, is used in the manufacture of hard, polycarbonate plastic for baby bottles, microwave cookware and other consumer goods, and it has been detected in nearly every human body tested.
Scientists and health experts have theorized for more than a decade that chemicals in the environment and in consumer products mimic estrogens and may be contributing to male and female reproductive diseases, particularly prostate cancer.
The new study of laboratory rats suggests that prostate cancer, which usually strikes men over 50, may develop when BPA and other estrogen-like, man-made chemicals pass through a pregnant woman's womb and alter the genes of a growing prostate in the fetus. One in every six men develops prostate cancer, a rate that has increased over the last 30 years.<snip>
Last year, the California Legislature considered a bill, introduced by Assemblywoman Wilma Chan (D-Oakland), that would have banned children's products that contained BPA or other plastic compounds called phthalates. It died in an Assembly committee after sparking a scientific debate and intense lobbying by the plastics industry.
