While it is always best to consult with your MD the purpose of a biopsy is to obtain physical samples so a trained pathologist can determine the grade of a cancer. The test revealed I had a Gleason 9 The scan suggested it was contained. That knowledge allowed my urologist to offer me 2 treatment options surgery or external beam radiation. Had the cancer escaped the prostate he said surgery would not have been an option. There are a lot of moving parts to this process from diagnosis to treatment and beyond. Prostate Cancer is slow-growing; you do not have to make a rushed decision and could get a second opinion or ask additional questions of the present provider.
