Researchers who studied 1,095 men showed that men need annual PSA tests so that their year-to-year change -- called PSA velocity -- can be monitored. They found that when PSA levels rose by at least 2 points during the year before surgery, about one in four patients died from prostate cancer within seven years. It raised the risk of death 10-fold. But if the PSA level had been increasing slowly before surgery, there was very little chance the patient would die from a prostate tumor.
