Regular exam suspected it in March, 2010 (PSA 4.8) I was diagnosed in April (PSA 5.6), biopsy done to confirm it, underwent cyberknife (radiation) in May.
On July 8 (6 weeks after last treatment I had a new PSA done and it had dropped to 1.8. A call to AOPA suggested having AME call regional flight surgean then (2nd Class would have expired on October) and sent copies of all records (in PDF)plus Dr.'s letter that there was no reason I could not fly via email to Regional Flight Surgeon.
They received it all on Tuesday, I called woman working on inputting my records to confirm receipt. Talked again on Fri and had new 2nd class special issuance on Next Monday good til October when the letter allows my AME to reissue new 2nd Class upon proof of no change (Need another PSA). She was a major help and took most of the anxiety out of the process.
I need a new PSA when I renew my medical (and probably a letter from my Urologist, but the whoole process was easy and fast.
