You have difficulty peeing
If you have trouble urinating or your stream is slow or weak, call your doctor—it could be one of the most common signs of prostate cancer. “Even if this happens once or twice and doesn’t persist, you should not ignore it because it’s not normal. Get it checked out right away,” says Ash Tewari, MD, chairman of the department of urology at the Icahn School of Medicine at Mount Sinai in New York. Although your toilet troubles are more likely to be caused by a condition other than cancer—they can be a symptom of UTIs in men, for example—you can’t be too careful, he says. The urge to go more often, especially at night, or loss of bladder control can be another sign that something’s not right.
There’s blood in your urine
If you notice blood in your urine, or if it burns or is painful to pee, ask your doctor about getting tested for prostate cancer, says Dr. Tewari. Because of the prostate gland’s proximity to the urethra and bladder, a tumor pressing on it may cause urinary symptoms. These are other health clues your urine may provide.
