A MRI is not going to identify the area as cancer. It will show areas of concern. A biopsy is the only test that will confirm if cancer or not.

I had a MRI with contrast first and found suspicious areas. I was told 70% chance the areas were cancer and a biopsy was ordered. It came back as prostrate cancer in several areas. A lot of tests later and finally went from intermediate to low risk, confined to prostrate, no bone, no surrounding tissues or organs invaded.

The biopsies can be done under anesthesia and through the transperineal area. Have it done this way and not rectal. You will have no pain (hopefully same as I) and you don't have the increased infection rate if done rectally and without anesthesia. I had no pain during procedure as was out and nothing after. If I had not been told I had a biopsy would not known I had one as no pain in the scrotum area at all.

My urologist (Mayo) used what they call MRI/Fusion to do biopsies and is highly accurate for urologist to find areas to biopsy.

Then my radiologist/oncologist did proton radiation therapy on the entire prostrate. He did that because he stated that did not want to take chance any area of prostrate that had cancer was NOT biopsied could have cancer in it and missed by biopsies and minute so treated including margins.
