Guys, Thanks for the replies.To answer a couple of points raised.The test 10 years ago(I now remember) was because I had,unusually, a UTI which was knocked out with antibiotics,I was referred and a consultant gave me digital exam which he said was satisfactory so I went away happy.
Nothing more till 18months ago when I had a pain in my hip and had talked to a mate who recently was treated with Pc so I went for a test and then jumped on the merry go round of treatment which as I said was all good(so far).
I suppose I am overthinking and don't want to take up the sites valuable time when my Pc has been zapped and hopefully eradicated but I think I will raise this point if my PSA continues to rise,next test is due April so we will see.
Good Luck to all of you in your own treatment and recovery.
