PsA prevalence based on the patient-administered screening tools was 12% to 16% higher compared with rheumatologists' diagnosis.
The prostate gland has two important functions: To produce ejaculatory fluid and to act as a barrier to retrograde UTIs. Prostate enlargement, or benign prostatic hyperplasia (BPH), can produce a constellation of unpleasant symptoms that result when the enlarged gland forces the bladder to work harder to expel urine.

In an update of its 2001 guidelines, the American Cancer Society stresses the importance of sharing the screening decision with the patient.

Can you tell me definitively whether the PSA-lowering effect of alpha blockers is similar to that of finasteride?
An experimental blood test detects prostate cancer so accurately that it may supplant prostate-specific antigen (PSA) levels as a screening tool. Researchers at Johns Hopkins University in Baltimore discovered an early prostate cancer antigen (EPCA-2) that functions as a biomarker. In a sample of 330 men, EPCA-2 levels were positive in 94% of those who…
