Prostate Cancer Risk May Be Predicted With as Few as 3 Tests

Prostate cancer screening beginning from ages 44 to 50 may rule out the risk of dying in half of men, according to a study that showed some men may need as few as three screening tests in a lifetime.

The research, which analyzed blood samples donated in the 1970s by 12,090 Swedish men, showed that 44 percent of prostate cancer deaths in the ensuing years occurred in 10 percent of men with the highest levels of PSA, a protein associated with prostate cancer at high levels. The study may help reduce unnecessary tests and treatment, said the researchers at Memorial Sloan-Kettering Cancer Center.
