Hepatitis C ups risk of head, neck cancers

Individuals infected with Hepatitis C virus (HCV) may be prone to certain head and neck cancers, a new study has found, pressing the need for screening and treatment for the most common blood-borne virus infection.


The findings showed that people with hepatitis C are two to five times more likely to develop certain head and neck cancers.

The risk increased 2.4 times for oral cavity cancers, 2.04 times for oropharynx cancers, and 4.96 times for larynx cancers.

"The findings tell us that the association between hepatitis C and oropharyngeal and nonoropharyngeal cancers is as high as its link to non-Hodgkin's lymphoma," said Harrys A Torres, associate professor, University of Texas in US.

HCV was long associated with liver cancers and non-Hodgkin's lymphoma and additional cancers, but there was no known association with a significant number of head and neck cancer.

For the study, published in the Journal of the National Cancer Institute, the researchers identified 34,545 patients who were tested for HCV between 2004 and 2014.
