re: Prostate cancer

I'd say none, really. I was a candidate for several reasons, the cancer was confined to a small area, overall health is good, I exercise, don't smoke, not diabetic, etc.
Removal of the prostate will create sexual and bladder problems - there's no way around that. Radiation may also cause some permanent urinary and bowel changes. Not all Urologist are skilled in cryotherapy and may not recommend it. It's relatively new. If not, I'd seek another opinion.
For now, Mrs ClusterCock and I enjoy an active sex life (for 64 and 57 years old) with no artificial help - pumps, etc.
