(March 22) — A blood test could soon offer an accurate diagnosis of colon cancer’s progression, according to Chinese researchers who say they’ve found two biomarkers that indicate the spread of the disease.
Colorectal cancer screening saves lives. However, many people who are at risk for the disease are not being screened according to national guidelines.
It is estimated that as many as 60% of colorectal cancer deaths could be prevented if all men and women aged 50 years or older were screened routinely. In most cases, colorectal cancer develops from precancerous polyps (abnormal growths) in the colon or rectum. Screening tests can find precancerous polyps, so that they can be removed before they turn into cancer. Screening tests also can find colorectal cancer early, when treatment works best.
