Blood test identifies HPV-associated head and neck cancers up to 10 years before symptoms

Human papillomavirus (HPV) causes around 70% of head and neck cancers in the United States, making it the most common cancer caused by the virus, with rates increasing each year. Unlike cervical cancers caused by HPV, there is no screening test for HPV-associated head and neck cancers. This means that patients are usually diagnosed after a tumor has grown to billions of cells in size, causing symptoms and spreading to lymph nodes. Screening methods that can detect these cancers much earlier could mean earlier treatment interventions for patients.
