A multi-analyte blood test, CancerSEEK, can detect 8 common cancer types, with high sensitivity and specificity, according to a study published online January 18 in Science.

"Our study lays the conceptual and practical foundation for a single, multi-analyte blood test for cancers of many types", the authors write.

A team at the Johns Hopkins University in Baltimore, Maryland, has been trialling a blood test that could act as a universal method for cancer diagnosis.

The new test would help early detection of cancers affecting the ovary, liver, stomach, pancreas, oesophagus, bowel, lung and breast, Xinhua quotes a statement from the Walter and Eliza Hall Institute of Medical Research in Australia. The median overall sensitivity, or the ability to find cancer, was 70 percent and ranged from a high of 98 percent for ovarian cancer to a low of 33 percent for breast cancer.

He added: "We envision a blood test we could use once a year".

Investigators said although the current test, in which larger studies are now underway, does not pick up every cancer, it identifies many cancers that would likely otherwise go undetected.

Cancer survival rates are directly linked to how advanced the disease is in a patient during diagnosis, which means that blood tests that can accurately detect the illness well before the symptoms are present is urgently needed.

He said: "Detecting cancer early, before the disease has spread is one of the most powerful ways to improve cancer survival and this interesting research is a step towards being able to do this earlier than is now possible".

Scientists at a university in the USA have made a breakthrough that could revolutionise the way cancer is diagnosed.

The next ongoing step is to trial CancerSEEK on people who have not been diagnosed with cancer.
