The Food and Drug Administration has approved a blood test that could effectively screen for colon cancer. The FDA approved Shield, the premier blood test of Guardant Health.
According to NBC News, the blood test is not meant to replace the conventional process of colonoscopy to check for colorectal cancer. However, since it costs less than a colonoscopy, it may increase the number of screenings for colon cancer and improve the chances of medical practitioners, and even patients, catching the illness early on.
