There's some evidence that prostate massage, prior to certain tests for prostate cancer, may increase the sensitivity of the test, making it more likely the cancer will be detected. Men suspected of having prostate cancer should not be treated with (or engage in) prostate massage, as this may cause tumor cells to break off and spread to nearby tissues. That said, a few small studies of the effects of prostate massage performed by a physician have shown it to be beneficial as a therapy for chronic prostatitis when paired with antibiotics. The massage increases inflammation and may promote the spread of bacteria to the urethra, other parts of the urinary tract, and the bloodstream. Overly aggressive prostate massage can also cause rectal bleeding, creating a risk of bacterial infection or aggravating hemorrhoids.įurthermore, manual prostate massage is discouraged for men with acute bacterial prostatitis. In the study described above, for example, 8.3% of participants reported discomfort after prostate massage. Massaging the prostate too intensely can easily lead to soreness. The tissues lining the prostate and rectum are delicate and vulnerable to cuts, tears, and abrasions.
