My husband has prostate cancer (diagnosed in 2006). He opted for brachytherapy and radiation treatments whichi were completed in 2007. For the past year, he has had blood and clots in his urine which in catheterization for several days during one of the more extreme episodes (~ 4 months ago). His urologist scoped his bladder concluding that no tumors were present -- his diagnosis was radiation damage to the bladder/vessels. The bleeding/clotting subsided considerably; however, last weekend, it became more severe. He was able to pass the clots and did not have to be catheterized. We have been exploring hyperbaric oxygenation treatment -- do you have any other suggestions?
