I had surgery on 06-06-2006 with path reports showing positive after surgery. PSA moved upwards so I went through radiation treatments in early 2008 for 12 weeks, but found PSA started rising again, we waited and watched until it jumped from 9.3 to 14 in June 2014, I then started injections of Leupron every 3 months and Xgeva every month for 1 1/2 yrs, I now have both injections every 3 months. My PSA has remained between .45 and 1.1 for the past 1 3/4 yrs. A bone scan reveled 2 spots on bone prior to the start of injections. I have asked about having another bone scan to check on bone metastasizing but was told as long as PSA remains < 1 it would not be needed. Does that sound correct or should we be looking for growth in the tumors?
