A simple blood test can detect colorectal cancer early, study finds

At a time when colorectal cancer is on the rise, a new study finds the disease can be detected through a blood test.

The results of a clinical trial, published Wednesday, in The New England Journal of Medicine, show that the blood-based screening test detects 83% of people with colorectal cancer. If the FDA approves it, the blood test would be another screening tool to detect the cancer at an early stage.
