Human Papilloma Virus (HPV) and a new form of head and neck cancer

Human Papilloma Virus (HPV) is considered the cause for Cervical and Genital cancers. In Sri Lanka Cervical Cancer is the second most common cancer among women.  Now it appears HPV can also cause throat and neck cancer and associated with those who have had many oral-sex partners.

People with HPV-positive cancer tended to have had many oral-sex partners, but there was no statistical association with tobacco smoking or drinking;

those with HPV-negative cancers were heavy drinkers and cigarette smokers but there was no association with sexual activity.
