New Blood Test Developed to Detect Early-Stage Colon Cancer

Washington, 10 Jul (ONA) – A team of researchers from the University of Chicago has developed a new, more accurate liquid biopsy test capable of detecting colorectal cancer in its early stages with 95% accuracy.

Unlike traditional biopsies that require the removal of tissue samples, liquid biopsies analyze a simple blood sample to detect cancer markers. However, these tests often face challenges in early detection due to the limited amount of cancer-specific DNA present in the blood during the initial stages of the disease.

To overcome this, the research team—led by Dr. Chuan He—developed a test that uses RNA (ribonucleic acid) instead of DNA to identify genetic changes linked to cancer.

Trial results showed that the test achieved an accuracy rate of up to 95% in detecting colorectal cancer from patient blood samples, including cases in the early stages of the disease.
