Technology Behind the Test, Fda approves new blood test for colon cancer

The test relies on a sophisticated technology called methylation-specific PCR(MSPCR). This method involves analyzing specific DNA sequences in the blood for the presence of abnormal methylation patterns. Methylation is a natural process that modifies DNA without altering its sequence. However, in cancer cells, methylation patterns can become disrupted, leading to unique changes in DNA that can be detected in the blood.

How the Test Works

The test works by extracting DNA from a blood sample and using MSPCR to detect the presence of these abnormal methylation patterns. The test specifically targets DNA fragments associated with colon cancer cells, which are shed into the bloodstream. If the test detects these altered methylation patterns, it indicates the potential presence of colon cancer or precancerous polyps.
