How Often Low-Risk People Should Be Tested for Prostate Cancer

“This enlarges the group with very low risk by 20% to nearly 90% at age 45. And they only need to repeat the PSA test 5 years later. Further follow-up aims to show that 10 yearly re-testing may be possible in these 90% of middle aged men. This would tremendously improve the harms of screening by increasing the negative predictive value of PSA,” Peter Albers, MD, a Professor of Urology at the German Cancer Research Center, and one of the authors of the research, told Healthline.
