Hello. The decision not to treat your prostate cancer was based on his age or that it was a low-risk prostate cancer. When cancer is not treated, are treated complications that appear. It is possible that discolored spot on knee and nodules on back are complications of Prostate cancer.However, you must go your doctor to examine your injuries, establish possible relation with prostate cancer and to prescribe right treatment. I wish you good health.
