The intensive testing currently prescribed to colorectal cancer patients after initial treatment doesn't significantly improve their survival chances or the detection of recurrence, according to two separate studies published Tuesday in the Journal of American Medical Association.

What it means: Researchers from both studies are urging an update to current guidelines to lessen the intensity of testing unless the patient is in a high-risk category.
