There are more cases of prostate cancer in parts of the world where there is greater use of the birth-control pill and Toronto scientists who made the discovery are now starting to investigate whether the water supply is the culprit.
“I think it is significant only because it is the first time the association has been looked at. It is significant because we are always trying to find the cause. Why is prostate cancer so prevalent in our society and the so-called Western world and less common in places like Asia?” asked lead researcher Dr. Neil Fleshner, head of urology at the University Health Network.
The study, published online Monday in the British Medical Journal, notes that prostate cancer is the most common cancer in the developed world and the use of oral contraceptives has soared over the past 40 years.
The research team cross-referenced data from the International Agency for Research on Cancer and the United Nations World Contraceptive Use report to pinpoint rates of prostate cancer and associated deaths and the proportion of women using common methods of contraception.
