Way to go Alan, that's fabulous news.
My own PSA did get down to about 50 at one point , but went back up to 116 a month or so back. Now I'm into the chemo in an effort to claw back a bit. No complaints on my part as I was diagnosed as stage 4 some 6 years ago!! I do miss tasting food and drink though. And with my new sparser hair and beard I look a lot like Beaky Buzzard from the Warner Bros. cartoons. When my PSA gets to your level we can share a virtual snifter of good cognac, til then I'll raise you a toast tonight.
Mike
