Richard gave you some great insights. A G7 is not insignificant ---the fact that the cancer is contained in the prostate now is quite significant and potentially good news. If you decide on waiting have you decided on what triggers will move you to the next step? If so just know that surgery may not be an option after the cancer has spread to other parts of your body.
While no one wants to jump into treatment -- none of us wanted to learn we had cancer either. That said what ever you choose I would suggest it is best to have a plan and some options in place before you need to make a decision. Dennis(ProstateCancer.net TEAM)
