I have been fighting prostate cancer since 2009. I have had robotic prostatectomy and IMRT radiation and am on third round of intermittent hormone therapy for prostate cancer. I recently found out that I had positive lymph nodes for the first time and a small tumor forming near the sacrum. Can anyone please tell me what to expect with this tumor near the sacrum. If it grows and the hormones do not control it, what can I expect. I would like all the information I can get about a tumor near the sacrum with prostate cancer.
