With a 3+4 they usually don’t recommend any ADT.

3.5 years after my surgery my PSA started rising, so I was given 8+ weeks of radiation. I was a 4+3. They gave me a six month shot two months before the radiation and none after. I didn’t have any more ADT until 2 1/2 years later when my PSA rose too much again.

Normally a 3+4 wouldn’t need additional ADT, But you had to have Radiation because your cancer had spread to more than just the prostate. In that case, some doctors want to go a year to a year and a half with ADT. It’s very possible that Prostate cancer has entered your bloodstream because it had spread beyond the prostate. You could still go into remission for many years, Sometimes it becomes dormant and doesn’t come back for decades, Continuing ADT would suppress the cancer from coming back for a longer period of time. It may not be necessary ask the doctor that wants you to go on ADT longer why?

I’ve been on ADT for eight years now. Really not had much of a problem with it. Had a lot of hot flashes in the beginning, but those are gone. I do run on a track a mile twice a day and go to the gym three days a week. I’m 78 and I’ve had prostate cancer for 16 years. I’ve lived this long because I’ve stayed on the drugs, While they can be a pain, they are beneficial.

You could get a decipher test, which would tell you the likelihood of having a reoccurrence. If it comes up with a low number, then you probably don’t need to go on longer than six months of ADT.
