Didn't want your post to get lost on another thread, because you are asking serious questions.
This is not an exact science. You will find a lot of opinion here about
this topic. Some doctors go all the way to .5.
It is just my opinion that without a prostate to manufacture PSA antigens, once you start seeing a rise, there is some unwanted activity. When you actually choose to initiate treatment is one of cionjecture. You did have a positive margin, so there quite possibly was some escape of the cancer.
In my mind, the real question is where is it now ? After 2 years, it may not be in the old prosate bed anymore. Certainly the CT and bone scan are good, buit with the low PSA, most likely they won'y find anything.
So, you have some options. Wait a few monnts and repeat the PSA, look into HT, or do the salvage radiation.
These are tough ones. The odds for salvage radiation aren't great. The side effects of HT aren't pretty, and the nerve wracking wait on top of depression make Active Survelliance a bummer.
Good luck, and keep posting to let us know how you are doing.
