I am also 4-3 and the PSMA Pet scan showed it is only the 7mm lesion and confined to the prostate. So, I elected for a genetic test (Oncotype) which came back as a 42. Under 40 you should do watchful waiting. I am also waiting for a 2nd opinion on the pathology report to come back. I will probably do radiation as having surgery is not something I will consider. Too many risks of spending the rest of my life in depends. It is very hard to trust anyone in the medical field after they all told us if you take the vaccine, you won't get covid, spread covid, get hospitalized from covid or die from covid. The medical profession has killed their credibility and now I do not trust anything from them. My desk is filled with Clinical Trial data and study results so do your research before making a decision on your own for what is best for you. I am also in my 70's and very active so I intend to be around a while longer but do get a PSMA Pet Scan for real helpful information on where your cancer stands.
