The blood test aims to identify individuals with improper control of the growth-promoting gene insulin-like growth factor 2 (IGF-2), which is associated with a higher risk of colon cancer. If successful, the test could help monitor those who need invasive colonoscopy or suggest dietary changes to reduce their risk.
