I've been through quite a bit since having my prostate removed in 2008. After 11 years it came back in the old prostate bed. I've had 36 radiation treatments while on hormones and worked outside 5 days in a row. I was very fatigued by Friday afternoon. It took me all weekend to recover for a Monday start over. Now 3 years since the radiation my numbers are once again coming up. I've had 3 PET/CT scans and they have all been clear. I'm not willing to treat just the numbers. I want to know where the cancer is and then I can make a decision about treatment. I'm 79 years old and in otherwise good health and a active lifestyle.
My advice to you would be to develop a attitude that it is what it is. All you and your team can do is make educated decisions about treatment or not. Your worries about this and that will not fix anything and will possibly do you harm. Get out and live a great life and take this stuff by the horns and wrestle it down. Be happy and good luck. There's lots of people with a lot more problems than you have!
