PHILADELPHIA (CBS) - There is no doubt that prostate cancer is a major health issue in this country. Last year there were over 200,000 new cases.

If untreated, cancer of the prostate will take your life in twelve years – that is an average. Screening is crucial because if it is caught early while contained in the prostate it can be a lifesaver.

The typical screening is done by a digital rectal exam and a PSA test. If these raise significant questions, a prostate biopsy may be necessary.

The most important point is that if you are a male over 40 you want to talk with your doctor about it.
