I think some more information would be helpful. What was your gleason grade and staging from the pathology report after your prostatectomy? What was your PSA post-surgery? Was the cancer confined to the prostate or was there anything outside the margins?

When was your last PSA test? what was the result?

No one can predict if cancer will recur. If caught early there is a higher likelihood that it can be cured or place in remission for a very long time. But everyone is different. The treatment plan depends on you in your discussion with your doctor; weighing the benefits and the risks of side effects that will impact your quality of life.

Listen to your doctor's recommendations, ask questions. Take the time to get informed about your type of cancer and possible treatment options. Schedule an appointment with a Radiation Oncologist and get a second opinion. You still have time on your side to decide what is best for you. Don't rush into treatment yet. And try not to worry too much.
