In 1990 my friend had a Radical Prostectomy with some sluffing off into the lymph. He was treated with Eloxin and Flutomide post operative. His PSA Gleason score continued to stay under 1.0 In 2002 he entered the VA system abd his PSA was been <.010, he received Zolodex treatment and it stayed constant until 2007 at.060. Last year they stopped the Zolodex injections as the VA said studies showed it was harmful to the bones. Since that time the PSA has increaed to (point) .53, the present reading. The Urologist had concerns about the rising PSA, and ordered a bone scan that was negative, a CT of the Pevis area, results negative, and now they will do a Prostatstint SPEC in the pelvic area. My concerns are the score on Gleason scale is under 1, and he is now 70 years old. Aren't all these nuclear tests bad for him? Should he be concerned that the cancer has returned with a score under 1.0 at his age, and the tests so far have all been negative? He has no signs of urination issues, no pain, just the rise of the PSA. Could someone please give me some information regarding these issues. He doesn't know if another opinion should be gotten and if the Urologist's concern is valid or not! So far they have been unsuccessful in finding any signs of cancer.and my concern is also so many nuclear tests! Please give me your help. Thank you
