According to researchers at the Memorial Sloan-Kettering Cancer Center in New York and Lund University in Sweden, a new procedure involving taking a blood test at the age of 60 proves as a better prediction of the risk of death from prostate cancer.

The scientists conducted a study analyzing blood samples which were collected between 1981 and 1982 in Sweden. The samples were from 1,167 men born in 1921, who were studied until they turned 85 or died.

Researchers found that in the 126 of the men were diagnosed with prostate cancer, 90 percent of related deaths occurred in the men who had the top 25 percent of PSA levels at the age of 60. PSA testing has been widely used for early detection of prostate cancer, and this study concludes that it may be an even better way of determining who should and should not be screened for prostate cancer.

A PSA level below 1 ng/ml indicates a 0.2 percent chance of death from prostate cancer. The scientists concluded that men with PSA level above 2 ng/ml at age 60 should be considered at increased risk of prostate cancer and should be regularly screened.
