A study of more than 96,000 people conducted by Dr. Ilir Agalliu and colleagues at Albert Einstein College of Medicine in New York has found that about 70% of all head and neck cancers come from human papillomavirus (HPV).
At the beginning of the experiment the participants took a mouthwash test for oral HPV infection to prove they are cancer-free. Four years later their mouthwash samples were compared with the samples of 396 healthy people.
And it turned out that people with HPV-16, which is typically transmitted during intercourse or oral sex, were 22 times more likely to develop oropharyngeal cancer than were those with no detectable trace of the virus HPV-16 in their samples.
Moreover, 132 of the participants with HPV -16 had developed some form of head and neck cancer. Actually, HPV itself doesn’t cause cancer, but certain strains do, causing fatal changes in the cells of the throat and mouth.
