Prostate cancer is the second leading cause of cancer-related death among men in the US. Fully 15% of men will be diagnosed with prostate cancer during their lifetimes. As men age, their estrogen levels tend to rise, stimulating cancer cells that are sensitive to estrogen. Prostate cancer is one of these estrogen-sensitive cancers. BPA tends to mimic the actions of estrogen, further increasing the probability of prostate cancer developing.
Strictly speaking, any man should do what he can to avoid exposure to BPA, but particularly those with a family history of prostate cancer. Things even as simple as touching fewer shiny paper receipts or looking for cans that specifically say "BPA free" will decrease the risk of contracting prostate cancer in the future.
