There may be some unintended grave consequences for the heavy use of birth control pills in nations like the United States. A recent study published in the online British Medical Journal Open found that those countries having a high number of women using birth control pills also have a higher incidence of men with prostate cancer. While the study did not make a definite tie-in, “researchers said estrogen hormones released in urine that recycle through the water supply could account for one possible explanation” for the correlation between use of the pill and increased prostate cancer, reported ABC News.
