A study is done and 50 yr old healthy men were picked randomly and assigned to either get a DRE screening test or New blood test. After 5 yrs 40 out of the 50 from the blood test were living after 2 yrs after being diagnosed in comparison with 15 out of 50 screened with DRE survived 2 yrs after being diagnosed with prostate Ca.
