"News that an influential panel of experts is advising healthy men not to be screened for prostate cancer with a widely used test is certain to cause confusion and anxiety among men and their doctors, and reignites a debate about the benefits and risks of screening tests.
The recommendations, to be officially announced on Tuesday by the United States Preventive Services Task Force, affect more than 44 million men age 50 and older who typically are candidates for a simple blood screen call the prostate-specific antigen (P.S.A.) test.
The panel, which already recommends against P.S.A. screening for men age 75 and older, will cite recent research suggesting that the testing does not save lives but does lead to unnecessary treatments that can cause impotence, incontinence and a number of other complications.
Here are some answers to common questions about P.S.A. testing and what the task force recommendations mean for men."
