New DNA Tests Aimed at Reducing Colon Cancer
New York Times

Two new DNA-based tests, one of them described at a meeting in Philadelphia on Thursday, hold the promise of detecting early — and sharply reducing — colon cancer, a disease that afflicts 150,000 people a year in the United States and costs an estimated $14 billion to treat.

The new tests could help most people avoid colonoscopies, which are routinely prescribed for people over age 50. Instead of screening the entire population, doctors could instead refer people for a colonoscopy only if they had tested positive in one of the DNA tests.
