COLON CANCER TEST

ANCHOR LEAD:  A NEW BLOOD TEST MAY DETECT COLON CANCER, ELIZABETH TRACEY REPORTS

A simple blood test may soon distinguish those with colon cancer from those without, if Johns Hopkins research holds up in clinical use.  Robert Getzenberg, professor of urology, and colleagues, have identified a blood marker that pinpoints the disease.

And what we found was that if we looked at normal versus cancer that is, can we separate someone walking down the street with colon cancer from those without the disease it was almost perfect in separating the individuals with colon cancer from the normal individuals. When we looked at those with different types of polyps we found that the marker was not elevated in the blood in individuals with hyperplastic polyps and these are very benign polyps that donít have an increased risk of developing colon cancer but as we went on to the more aggressive forms of polyps we found that the levels of CCS 3 and 4 did increase. :30

A positive blood test would require colonscopy and biopsy for confirmation, but would also identify the disease much earlier.  I’m Elizabeth Tracey reporting.
