Researchers from Queen Mary, University of London have developed a new gene test that can detect pre-cancerous cells in patients with benign-looking mouth lesions. The test could potentially allow at-risk patients to receive earlier treatment, significantly improving their chance of survival. The study, published online in the International Journal of Cancer, showed that the quantitative Malignancy Index Diagnostic System (qMIDS) test had a cancer detection rate of 91-94 per cent when used on more than 350 head and neck tissue specimens from 299 patients in the UK and Norway. Mouth cancer affects more than 6,200 people in the UK each year and more than half a million people worldwide, with global figures estimated to rise above one million a year by 2030*. The majority of cases are caused by either smoking or chewing tobacco and drinking alcohol.
