Welcome to HW. First things first-- slow down, things aren't gonna be resolved immediately, no matter what approach is selected. It sounds as if the numbers are reasonably ok, as far as having cancer goes. Nothing really drastic or advance, nor life threatening. The job now is to take the time to study, research and get second opinions on what is available or recommended to you. You should consult with a surgeon, a radiation ocno, and a medical oncologist, ask lots of questions and see what they say and go from there with a decision.
The doctor saying all three of those treatments: does he mean all together or that's the choices of a single treatment available? In advanced cases, it might be recommended that all three be done back to back, so to speak, but from the numbers you state, that seems like overdoing it for now. It would help to have further details and his Gleason score.
As far as scans, as you say, there are conflicting info about
their accuracy, especially for low-load cancer patients, who aren't in an advanced, metastatic stage. I'd discuss this further with the doc, and begin to schedule those referrals for second opinions with some other specialities.
Something to keep reminding yourselves: this is the first step in a journey, and there's many more miles to go. Many, many options available...
