Men who take popular pain killers regularly have lower levels of
PSA , which is a marker used to detect prostate cancer.
Researchers at the University of Rochester analyzed data taken from over 13 hundred men age 40 and older.
They found those who took painkillers called n-said's, which include aspirin and aleve, had PSA levels 10 percent lower than men who didn't use the drugs.
