Typical of most drugs, the drug linked to male breast cancer, Finestaride, works by addressing symptoms and causing the body to do something unnatural - in this case by preventing testosterone from being used by the body which results in shrinking of the prostate glands. When you prevent testosterone from being used, one common side effect is for males to develop female-like breasts. Not surprising then to see an increased incidence of breast cancer, which is normally quite rare among men.
When you take something artificial made by man into man's body which was made by God and which developed by consuming natural foods there is a very good chance that there will be unnatural consequences.
Thanks for the post! (you should also post that in the Prostate, Cancer Support and News forums)
