My wife suggested I had a prostate test a while back. No symptoms etc. BUT PSA was 5, biopsy showed Gleason of 8 (5+3). although 3 samples were benign, one 4+3 and one 3+3 BUT with one showing high grade PIN and one showing 5+5. MRI, full body bone scan and CT scan all show no spread. I am due to have a radical prostatectomy within weeks, but am not too sure about the op (DaVinci robotic keyhole surgery) and wonder at age 74 whether a 'watch and wait' would be a viable option. Any thoughts please.
