Groundbreaking blood test can detect cancer years before symptoms appear

A new blood test can detect various types of cancer years before previously possible with traditional detection methods, according to a new research published in the scientific journal Nature Communications.

Early detection of cancer has the potential to significantly decrease death rates caused by the disease. Scientists have tried for years to develop a cancer screening-test that would reliably detect malignancy potential before tumor cells have the chance to spread, making treatment more effective. But until today, most attempts were unsuccessful or had partial results at best. 

Developed by a Sino-US startup, the groundbreaking new blood test is referred to as PanSeer. It was developed by an international team of scientists at the University of California, who were successfully able to diagnose five different types of cancer long before symptoms appeared in the patients it tested.

The five types of cancer that PanSeer can currently detect are stomach cancer, esophageal cancer, bowel cancer, lung cancer and liver cancer, all fairly common.

The test is based on a technique that was developed over a decade and allows detection of malignant tumors in their early stages, which haven’t led to any symptoms yet and were thus undetectable with previous methods.
