Prostate cancer is the second leading cause of cancer death among men, and its something of an enigma. Unlike cancer in most other sites, tumors arent surgically extracted from the prostate. Instead, the entire prostate is removed, leading to short- and long-term side effects in patients. Also, it may be the only type of cancer that is diagnosed via blind biopsy the urologist never actually sees the tumor and must resort to taking multiple needle-stick samples from throughout the prostate. Even when the presence of cancer is confirmed, theres still a great amount of inaccuracy in determining its stage (or relative aggressiveness).
Judging prostate cancer’s aggressiveness is very important because despite the number of men it kills, the vast majority of cases are not life threatening. Mo
