You need to understand that Prostate cancer treatment is BIG business.
And Doctors and indeed, the whole system is a business.
On the other hand, we who suffer from Pca need treatment.
Then, just to muddy up the waters more, EVERY treatment (that I know of) has serious side effects. Furthermore no one can tell ahead of time how bad they may be.
One person after undergoing treatment "A" will suffer only slight or no side effects, while the next patient with same conditions and same doctor may have bad side effects.
Basically, although far from perfect the treatment options are better than they were 70 years ago when when the medical profession just castrated men with Pca and hoped that it would buy some time.
