Your prostate biopsy pathology report is the key to understanding your particular case of prostate cancer. It is far more important than PSA, stage, bone scans or anything else. The information in the pathology report tells doctors how fast your cancer is growing, how extensive it is within the prostate, and the likelihood of capsule penetration (leakage of cancer cells outside the prostate). The pathology report is the cornerstone to tailoring treatment to the extent and aggressiveness of your prostate cancer, as well as to the calculation of your 10-year ICR.
