  • The test could identify cancers of the ovary with 90 per cent accuracy

A new blood test shows promise for detecting many types of cancer, even in the early stages of the disease, according to a new study.

In addition, the study included patients who had already been diagnosed with cancer, so more studies are needed to investigate whether the test can detect cancer in its earliest stages, before people are typically diagnosed with the disease.

The test is called liquid biopsy and it's being hailed as the "holy grail of cancer research".

"This is potentially the holy grail of cancer research, to find cancers that are now hard to cure at an earlier stage when they are easier to cure, and we hope this test could save many lives", lead study author, Dr Eric Klein, told The Telegraph. "We need more and more and more samples" to determine the true accuracy of the test.

Simon Stevens, chief executive of NHS England, said such advances in medicine could "dramatically transform" the tools doctors use to screen cancer.

"In particular, new techniques for precision early diagnosis would unlock enormous survival gains, as well as dramatic productivity benefits in the practice of medicine". In the soon-to-be presented research, the team sampled 1,627 volunteers, 749 of which did not have cancer and 878 that had various types of newly detected not yet treated cancer, CNN reported. So far, it has proven particularly capable of detecting ovarian and pancreatic cancer, both of which have significantly lower mortality rates when caught early enough to perform surgery as a means of removing the cancer.

It was 77% accurate in diagnosing lymphoma, 73% accurate for myeloma, and 80% accurate for liver and gallbladder cancers.

Triple-negative breast, lung, oesophagus, head and neck cancers were also picked up with more than 50% accuracy.
