New blood test to detect if cancer has spread around the body

Cancer researchers have developed a new blood test that could improve diagnosis and treatment for patients. The test is the first to be able to detect not only the presence of cancer, but also the spread of the disease around the body, which is often categorised in cancer stages. The test, developed by researchers at University of Oxford, uses a new technique called NMR metabolomics, which identifies the presence of biomarkers in the blood, called metabolites. These are small chemicals that our body naturally produces. The test has successfully identified metastatic cancer in 94% of 300 samples received.
