A medical study has revealed that kissing can cause cancer. Kissing has overtaken smoking and drinking as the leading risk factor for developing head and neck cancers. The humble French kiss can pass on human papilloma virus (HPV), and Head of Maxillofacial and Head and neck Surgery at the Royal Darwin Hospital, Dr Mahiban Thomas, said the virus was responsible for a ‘tsunami’ of cancer cases.


Dr Thomas told NT News if you became infected by HPV in the oropharynx, your risk of developing head and neck cancer was 250 times higher than that of someone without the virus. While most commonly associated with cervical cancers in women, HPV can affect both men and women. There are more than 100 types of the virus, but it is ‘Oral HPV’ that can cause cancers in the oropharynx.

The Centers for Disease Control and Prevention said studies suggested Oral HPV could be passed on during oral sex or open-mouthed or ‘French’ kissing, and about 7% of people have oral HPV, but only 1% of people have the type of oral HPV that is found in oropharyngeal cancers.

‘’High-risk behaviours are oral sex, multiple kissing partners, and more recently there are reports even ‘petting’ can lead to infection.  “If someone has kissed in excess of six people their risk of contracting HPV is higher, or if someone has kissed in excess of nine people the risk is significantly higher again,” Dr Thomas told NT News.
