Zee Media BureauNew Delhi: Scientists may now be able to detect oral cancers several years before the clinical onset of the disease, according to a new study.An international team led by World Health Organisation’s scientists used a blood test to detect antibodies to a high-risk type of human papilloma virus (HPV16).The presence of these antibodies indicated a very high risk of developing an HPV-associated cancer of the oropharynx.“These results are very encouraging. Up to now, it was not known whether these antibodies were present in blood before the cancer became clinically detectable. If these results are confirmed, future screening tools could be developed for early detection of the disease,” said Dr Paul Brennan, Head of the Genetics Section at IARC and the senior author of the study. “To date there are no available markers for early detection of this cancer,” he added.
