New research has suggested that oral sex is the main culprit behind a reported ‘epidemic’ of throat cancer in countries like the US.
According to Professor Hisham Mehanna from the Institute of Cancer and Genomic Sciences at the University of Birmingham, the human papillomavirus is to blame.
Writing for The Conversation, he explained how for oropharyngeal cancer, the main risk factor is the number of lifetime sexual partners, especially oral sex.
According to the American Cancer Society, cases of HPV-linked oropharyngeal cancer, a type of throat cancer, rose annually by 1.3% in women and 2.8% in men between 2015 and 2019.
On their part, the CDC estimate that around 70% of oropharyngeal cancer are caused by HPV infection – affecting the tonsils, base of the tongue and the back of the throat.
Further research in 2021, researchers discovered that people with 10 or more oral sex partners were more than four times more likely to develop HPV—related mouth and throat cancers.
This was more worrying considering that the CDC state that 41% of teens between ages 15 and 19 participate in oral sex. Those between 15 and 24 were found responsible for nearly half to the 26 million new STD infections in 2018.
