A simple blood test for colon cancer
Date:11/20/2008

r patients to undergo the colonoscopy, and then polyp removal, if necessary.

The novel invention is based on testing CD24, the oncogene for colorectal cancer. It utilizes the fact that polyps in the colon emit biomarkers, which can be detected in the blood at very low levels. Recent studies show that the test can correctly identify adenomas, the polyps that convert to colon cancer, at a success rate of more than 80%.

Some patients forego colonoscopy not just out of fear or distaste, but due to its high cost. Here, too, the breakthrough is significant. While traditional colonoscopies cost about about $1,500 per test, Prof. Arber's procedure is expected to cost much less ― $50 to $100 per test.

Prevention Is Still the Best Medicine

Prof. Arber recommends a number of preventative steps against colon cancer, especially by those at risk. "There are some lifestyle choices people can make to prevent malignancies," he says. "Eating well, exercise, and avoiding smoking and drinking are very important."

Prof. Arber is also working on a drug that prevents the growth of polyps in the colon.
