Need some advise, After my first biopsy, I had one core with a Gleason 6 then downgraded to a PIN after a second opinion. At that time my PSA was 3.7
> now 3 months later my PSA is 4.2. Doc wants to do the frontal mutable core biopsy. This will be the second one in 8 months. He said that the trend is not good and is recommending radiation if the biopsy finds a 6 or 7. Do I let him do the second biopsy or wait and just keep checking PSA and what number is safe.
