You will have DRE, Ultrasounds, MRI, etc. but a Biopsy is the only way to diagnose the tumor . You can also get as many opinions as you like, and at some stage you may get the answer you want, but whether that opinion proves to be correct, only time will tell, but by then may be too late. Many prostate cancers have no symptoms . The best advice is to get tested early and act on a high PSA . Having your head in the sand will solve nothing and make future management more difficult ...... Bob
