Even MORE reason to have Decipher! 3+3 Gleason is merely a starting point - no guarantees it stays this way as Gleason is based on observed numbers of dysplastic cells (and their degree of dysplasia) in a given area. If your Decipher comes back High Risk for metastasis then you can be assured of an increase in your Gleason over time.
My friend went from a 3+3 to a 4+3 in one year but luckily his Decipher score was low; he still needed treatment with those numbers and chose Cyberknife. He’s doing great.
