To diagnose prostate cancer, at an early stage, it can be diagnosed with screening with PSA (prostate-specific antigen) blood test or a DRE (digital rectal exam). At the early stage, there are no symptoms whatsoever, but over time, the symptoms they cause become more obvious. When you suspect cancer from the results, further tests have to be done to confirm the diagnosis. This can be actually done or made with a prostate biopsy. Once your doctor suspects you might have prostate cancer, they will ask certain questions about your urinary and sexual problems.

With the PSA test, most men who do not have prostate cancer have PSA levels under four nanograms per millilitre of blood. The higher the PSA level, the higher the chance of having prostate cancer.. Further, if a DRE or PSA test detects an anomaly, you might be recommended further tests to determine if you truly have prostate cancer. Some of these tests are ultrasound, collection of a sample of the prostate tissue, and MRI fusion. These tests can determine how far it has spread and how aggressive it is.
