How Methyl Scan Blood Test Detects Cancer Early: Medical science is rapidly approaching a stage where a simple blood test can provide clues to many serious diseases. Researchers at the University of California, Los Angeles, have taken a significant step in this direction, developing a new test that could help detect many diseases, including cancer, at an early stage. Let us explain what the research has revealed.

What did the research reveal?

This research, published in the prestigious journal Proceedings of the National Academy of Sciences, suggests that a single blood sample can assess the body's overall health. Early detection remains a major challenge in the medical field. Diseases like cancer, if detected early, are much easier to treat. However, existing tests often focus on a single disease and are often expensive or inconvenient.

What was this technique called?

This new technology is called "MethylScan." This test analyzes small fragments of DNA present in the blood. This DNA comes from different cells in the body, and when cells die, they release their information into the blood. The unique feature of this test is that it reads methylation patterns in DNA. These are chemical markers that change depending on the condition of the cells. This means that healthy and diseased cells have different methylation patterns, which, when identified, can indicate disease.

What was done to deal with the difficulties?

A major problem with blood-based testing is that most of the DNA in the blood comes from normal cells, making it difficult to detect signs of real disease. This is called background noise. To overcome this challenge, researchers developed a new technique that removes unnecessary DNA and focuses only on essential and informative DNA. This increased test accuracy and reduced costs. The study involved testing more than 1,000 people, including cancer patients, those with liver disease, and healthy individuals. The data was interpreted using advanced computer analysis.

What was the result?

The results were quite encouraging. The test detected approximately 63 percent of cancer cases overall and more than half of early-stage cases. In liver cancer, in particular, the detection rate in high-risk groups was nearly 80 percent. Another significant advantage is that the test can also identify which organ is affected, helping doctors direct further investigations in the right direction. However, this technology is still in its early stages and requires further large-scale testing before it can be widely used.
