AI-powered blood test could identify brain tumours missed by GPs

An artificial intelligence system that analyses a drop of blood could help to identify patients with brain tumours. Researchers said that within 18 months the technique could be widely used in the NHS after a trial indicated a 90 per cent success rate in identifying gliomas, the most common form of brain tumour. More than 9,000 people a year in the UK have primary brain tumours diagnosed, of which about half are cancerous. At present a brain scan is the only reliable way of identifying a tumour.
