New study blames oral sex for types of cancer; know more about it

With the rise in cancer cases and that too of many types, there needs to be understood the reasons behind what is causing it. Even more as to the kind of lifestyle changes that have occurred over the years in our life and how that may have stoked the chances of cancer  cases in humans.

It is in this context that smoking and having oral sex with multiple partners have been identified as reasons why men may be at increased risk of developing a type of head and neck cancer that is triggered by exposure to the human papilloma virus, known as HPV-related oropharyngeal cancer, warns a new study.

The risk was much lower among women, anyone who did not smoke, and people who had less than five oral sex partners in their lifetimes, found the study published in the journal Annals of Oncology.

“Most people perform oral sex in their lives, and we found that oral infection with cancer-causing HPV was rare among women regardless of how many oral sex partners they had,” said one of the study authors Amber D’Souza, associate professor at the Johns Hopkins Bloomberg School of Public Health in the US.

“Among men who did not smoke, cancer-causing oral HPV was rare among everyone who had less than five oral sex partners, although the chances of having oral HPV infection did increase with number of oral sexual partners, and with smoking,” D’Souza added.

There are over 100 different kinds of HPV but only a few are known to cause cancer; infection with HPV 16 or 18 is already known to trigger most cervical cancers, and HPV16 also causes most oropharyngeal cancers.
