The Department does not hold information about the number of men diagnosed with prostatitis or benign prostatic hyperplasia centrally. With regard to benign prostatic hyperplasia, in 2002, the National Institute for Health and Clinical Excellence published ‘Improving Outcomes in Urological Cancers’ which set out best practice for the NHS for the diagnosis, care and treatment of patients with urological cancers. The guidance estimates that benign prostatic hyperplasia is least four times as common as prostate cancer.
