Researchers say blood test can detect cancer years before symptoms



A blood test can pick up cancers up to four years before symptoms appear, researchers say, in the latest study to raise hopes of early detection.

A team led by researchers in China say the non-invasive blood test – called PanSeer – detects cancer in 95% of individuals who have no symptoms but later receive a diagnosis.

“We demonstrated that five types of cancer can be detected through a DNA methylation-based blood test up to four years before conventional diagnosis,” the team wrote in the journal Nature Communications.

They said the test was unlikely to be predicting cancer but rather picking up on cancerous growths that had not yet caused symptoms or been spotted by other methods.
