The Value of PSA Screening
Dear OncoLink "Ask the Experts,"
In the "Ask the Experts" article entitled Prognosis After Prostatectomy, a woman asked whether her family physician had erred by not routinely screening her husband for the past 10 years with a PSA.
The answer given was that he should have had annual PSA testing in conjunction with a digital rectal exam starting at age 50-55. There was no mention of the controversy surrounding this approach in the medical community or the lack of hard data to support this approach (though some data is now emerging). Please elaborate on this.
