A new study has suggested that oral sex increases the risk of head and throat cancer; the oral sex could be cunnilingus (sucking of vagina) or fellatio (sucking of the penis).
The cancer according to the study is associated with Human Papilloma Virus (HPV-16), a virus that is commonly found on human skin and the lining of external orifices like the vagina, mouth and anus. The virus is most concentrated in the cervix where it is known to be responsible for the cancer of the cervix. It is also found in the penis but in less quantity, hence the cancers of the mouth and throat are commoner in men than in women
The study was published in the journal JAMA Oncology
