Dad has had prostate cancer for several years, was diagnosed 12 years ago. They wouldn't do surgery because of his heart condition, instead he had radiation, medication. He didn't show with progression until six years after radiation, and then it was back on medication and PSA testing. Dad is use to the routine, me, I feel like I'm sitting on the edge all the time with this, feel like I need to be ready to deal with a serious cancer spread at any moment, does prostate cancer spread that way? I'd like to be prepared to help dad the best I can.
