DNA ‘catch-and-release’ enables urine test for brain cancer
Researchers have developed a novel way of detecting brain cancer, using nanowires to ‘catch-and-release’ DNA in urine, enabling them to detect mutations that signify the presence of a brain tumor. Their method may one day mean that invasive tissue biopsies are no longer required.The definitive way to diagnose a brain tumor is to take a tissue biopsy, which involves surgery to remove a small amount of tumor tissue for examination under a microscope. This is obviously invasive and uncomfortable for the patient. But what if…
