Thanks for your comment. Since there were no absolute definitive indications of prostate cancer, plus the calcification issue, I plan to continue PSA tests every 4 to 6 months to ascertain the velocity of PSA increases.

The proton radiation done in 2010, some 15 years ago is and was the best option for those who have the time and finances to undergo proton radiation therapy. I recently looked at the bill. Each proton day was $3600 and that was in 2010. With 2.5 months, that should be 50 days of billing. Today's expense must be much more. I fortunately had TriCare for Life (retired military), so aside from housing, my portion was minimal.

I am in excellent health with exercise daily both at home and outside. Time will tell.
