Thanks for all your replies.
At the moment the only information we have is that he had a routine check up at the doctors in early August and his PSA came back at 16. He hasn't been retested nor has he ever had a test in the past.
He is 68 and has also recently been diagnosed with Parkinsons.
His MRI showed an abnormality on his right side of the prostate but no other information.
We have come round to the fact it is probably cancer. However with the urologist sending him for CT and bone scans before a positive biopsy, we are starting to get worried he knows omething we don't as from what I have read they normally wait for a positive biopsy first.
Thankyou all again.
