Diagnosed in 2012 at 64 yrs old. Had an elevated PSA at 6.5 at that time. Selected active surveillance. Was PSA tested every 6 months for 10 yrs. PSA fluctuated between 3.5 and 5 for those ten yrs. Also had 3 MRIs and 3 biopsies over the 10 yr. period. In July of 2022, PSA spiked to 22.5. PSA re-tested again after 30 days and PSA had dropped back to 4.8. History of significant BPH also over the 10 yrs. of surveillance. Had my 4th MRI along with a PET scan because of the one significant PSA spike. No metastasize seen. Felt I had done active surveillance long enough. Chose to have Proton Beam treatment in October 2022 at my present age of 74. Praying for positive results.
