Researchers find way to screen blood samples to detect presence of precancerous polyps in the colon

Canadian researchers have found a way to screen blood samples for molecular traces that indicate the presence of precancerous polyps in the colon, a key warning sign for colon cancer. Their results, published this week in the journal Biomedical Optics Express, from The Optical Society, may yield a cheaper and less invasive initial screening test for colon cancer that could complement colonoscopy, though further clinical trials will need to demonstrate the safety and effectiveness of the blood test before it is routinely used.
