I was diagnosed 4 years ago at age 60 with a slow growing cancer in my prostate. Knowing the risks attached to these treatments, I opted for watchful waiting. My PSA scores have unfortunately been increasing recently, as have my urination issues. Last month my oncologist advised that the nodule on my prostate has increased in size, and he recommended that I get treatment this year. After a lot of research, I am leaning towards brachytherapy (radioactive seed implantation)....but. The oncologist advised that my butt would be too sore to ride my bike for awhile. Any comments or guidance? Thanks.
