It is not only guys who have had apparently successful treatments who wonder whether they might just as well have done nothing. My dad, after being diagnosed with what the pathologist reported as a Gleason 7 tumor (psa 14 or so) had a Lupron shot, external beam radiation, then when the cancer recurred, Casodex and Lupron for some time, zoledex, a second biopsy, then a salvage cryo procedure, a pulmonary embolism following that procedure (so anti-coagulant shots every day for life), ketoconazole and prednisone, then taxotere, biopsies of several other organs to determine the extent of mets, spot radiation to bones, three other semi-experimental chemotherapies, and probably some other stuff I am forgetting. In the end, he died around 7 years after diagnosis. Maybe he would have lived the same 7 years without any treatment at all? Or a bit less, but better quality? As the famous quote from Ain't Misbehavin' said, "one never know, do one"?
