Most prostate cancers are first found during testing with a prostate-specific antigen (PSA) blood test or prostate examination whereby the prostate is situated in close proximity to the rectum and allows the ability to feel the posterior (or back half) of your prostate and detect possible cancers. . Early prostate cancers usually don’t cause symptoms, but more advanced cancers are sometimes first found because of symptoms they cause.
If cancer is suspected based on results of tests or symptoms, further investigations will be needed to confirm the diagnosis. The actual diagnosis of prostate cancer can only be made with a prostate biopsy.
