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.
The test, developed by Guardant Health, can be done from a blood draw. The company says its test detects cancer signals in the bloodstream by identifying circulating tumor DNA.
