My brother is over the age of 50, making frequent trips to the bathroom during the night? these symptoms may indicate that he has a non-cancerous enlargement of the prostate or a cancerous enlargement of the prostate, how to determine , is there any other symptoms?

Sheryl's answer pretty much covered it and I want to add my 2 cents. A visit to the urologist for a PSA test and if suggested by the findings of the PSA, a biopsy to confirm/rule out cancer is really the only sure way. I had a lot of trouble with the first doctor I saw who neglected to refer me to a urologist ( I was almost 60 and my prostate was only slightly enlarged so he apparently felt no need to tell me about it) and further trouble with the first urologist I DID get to see over a year later. looking back, the worst mistake I made in handling my prostate cancer was my hesitancy to go to a different urologist. Be very proactive and don't only request the test, demand it if necessary! Best wishes for preferably a non-cancer diagnosis and if cancer is diagnosed, that it is caught early.
