Hello Quincy, First of all, congrats on being 87 and still so physically active; I am sure that the two go hand in hand!
The short answer is ADT and salvage radiation…that’s pretty standard for recurrence.
You can also go the total hormone route, using meds to keep your PSA low and your cancer from spreading. But those meds over time exact a cost and your quality of life could be impacted adversely. Your 87 years could suddenly feel like a lot more!
Your age is the SINGLE factor that most doctors are going to focus on; do they treat you ‘palliatively’ with hormones, fearing that radiation may be seen as being too aggressive for a man your age? It IS something that goes through a practitioner’s mind and something you should be aware of when you have your consults.
You really have to know what YOU want, and not what your doctor wants. So many times, well meaning docs do what they think is ‘best’ for us; in reality, they do what’s best for them. Just throwing a bunch of pills at you is the path of least resistance, IMO…
With your level of fitness, I don’t see why you should be treated any differently than I was, completing SRT and 6 months of ADT at age 70. Your physiological age is probably a lot closer to my chronological one…Best of luck in your decision.
