Whatever their is, your cancer does not appear widespread if your 7 was not seen this time. It is very possible your prior reading of the 7 core was a 6. Second reviews of biopsies will often change a Gleason score on a core. I would imagine this biopsy would have covered that same area. With a clear MRI that is encouraging. Have you had a retest of your PSA. Maybe the 11 was a false reading. You can ask to have your biopsy tissue sent off for Decipher testing. Inquire with your doctor about the PSE blood test or ExoDx urine test. Those tests are usually helpful in deciding to go forward on a biopsy, but in your case can determine how aggressive cancer yours might be.
