A)The National Cancer Institute used to consider a PSA level of 4.0 ng/mL or lower to be normal, but men with normal PSA levels may still have prostate cancer. PSA levels above 4.0 ng/mL or PSA levels that fluctuate could be an indication of prostate cancer, but it could also indicate prostatitis or urinary tract infection. Therefore, PSA levels must be interpreted in conjunction with the patient's health history and other diagnostic tests to confirm a diagnosis of prostate cancer.
