Researchers from the Cancer Research UK Cambridge Institute have developed two tests that can detect the presence of glioma, a type of brain tumor, in patient urine or blood plasma.
The team say that a test for detecting glioma using urine is the first of its kind in the world.
Although the research, published in EMBO Molecular Medicine, is in its early stages and only a small number of patients were analyzed, the team say their results are promising.
The researchers suggest that in the future, these tests could be used by GPs to monitor patients at high risk of brain tumors, which may be more convenient than having an MRI every three months, which is the standard method.
