(NEWS-MEDICAL) — A team of researchers at the University of Bristol and University of Oxford found that PSA screening could only identify low-grade prostate diseases and failed to detect some aggressive and lethal prostate cancers.

The study underlined the flaws of a single-PSA screening and suggested the need for more precise options for the diagnosis of such cancers.

Annually, the number of cases of prostate cancer and deaths reported in UK were 47,000 and 11,000, respectively, and in US, the reported numbers were 165,000 and 29,000, respectively.
