Because symptoms for prostate cancer are rare, screening for this disease is especially important. For men at average risk, the American Cancer Society recommends getting routine screenings for prostate cancer starting at age 50. If you have multiple risk factors or a family history of prostate cancer, talk with your doctor about how frequently you should receive screenings.
If your physician detects an abnormality when performing a screening for prostate cancer, they can confirm a cancer diagnosis by examining biopsy cells through a microscope. The pathologist can then determine the aggressiveness of the tumor on the Gleason scale, a grading system that categorizes the patterns of prostate tumor cells.
