Blood Test May Spot Early Colon Cancer
Noninvasive Colon Cancer Screening May Catch More Cancers, Researchers Say
Blood Test for Early Colon Cancer Is Holy Grail continued...
Leonard Augenlicht, PhD, a professor of medicine and cell biology at the Albert Einstein College of Medicine in the Bronx, says that the only definitive early screening test for colon cancer is the colonoscopy. "It is not as bad as it sounds, but many people are reluctant, so we looking for better noninvasive tests," he tells WebMD.
"This could be a noninvasive test that is relatively simple to perform, but the big question is just how efficient or valid is this test," he says.
"The danger is the risk of a false-negative result," he says. "If someone is told that they are negative on the basis of this test or another blood test, and that discourages them from more definitive testing, cancer could be missed."
