A study published in the New England Journal of Medicine was done to compare the effectiveness of a variety of colorectal cancer detection methods compared to a new method. It was found that the new fecal DNA test (detects mutated tumor DNA in feces) detected slightly more than half of all invasive colorectal cancers and was better than the Hemoccult II which is the current standard non-invasive screening test (detected only about 13% of cancers). The fecal DNA test was also showed double the sensitivity of the Hemoccult II test for pre-cancerous tumor detection. The biggest drawback of this new testing method is the price which is at least 20 times more expensive.
