94% of men discover they have prostate cancer from screening tests. Only around 5% of men discover it from urinary or erectile symptoms. Therefore, it is vitally important for men to do prostate cancer screening.
From these screening results (PSA test, DRE, Biopsy and Other Tests) if prostate cancer is present, it will be graded and staged. Grading means to determine how aggressive the cancer is. Staging helps determine how far the cancer has spread in the body.
