With prostate screening using the PSA test, you can detect prostate cancer early. Common symptoms of prostate conditions include difficulty urinating, erectile dysfunction, or potency disorders. These symptoms can result from changes in prostate size, inflammation (prostatitis), or urinary tract infections. They can also be an early indicator of prostate cancer.
This home test measures the prostate-specific antigen (PSA). Prostate cancer cells usually produce more PSA than benign cells, so the level of PSA in the blood rises. Elevated PSA levels in the blood are also indicators of other diseases, such as inflammation.
