Oral sex may contribute to an increase in the number of occurrences of throat cancer, health experts say.
Jamie Theakston, a 53-year-old UK radio host, has revealed that he has stage one laryngeal cancer after listeners detected a change in his voice.
Theakston revealed this week that he will be taking a vacation from his work at Heart Radio, according to Mail Online.
“Around 70% of throat cancer cases are caused by HPV,” said Dr Hisham Mehanna of the University of Birmingham, adding that having several oral sex partners can increase the risk up to ninefold.
Doctors have long connected smoking and alcohol intake to head and neck cancers, but new evidence suggests that human papillomavirus (HPV) plays a substantial role.
He stated that those who have several oral sex partners are up to nine times more likely to develop throat cancer, commonly known as oropharyngeal cancer.
He stated in The Conversation that throat cancer has been “rapidly increasing in the west,” to the point where some have labeled it “an epidemic.”
According to study, around eight out of every ten people will carry HPV on their bodies at some point, with roughly one-third of the population infected at any given moment.
It is most typically found on and around the genitals and usually causes no problems—the virus is thought to be so innocuous that the body’s immune system does not naturally attack it.
However, for unknown reasons, the virus can infect body tissues and cause cell alterations that lead to cancer.
There are about 150 different strains of HPV, but only about 12 are cancer-causing. HPV 16 and 18 are the most frequent high-risk strains that can result in oropharyngeal cancer.
Both the United Kingdom and the United States are witnessing a “throat cancer epidemic,” with roughly 12,800 new cases in the former and 71,100 in the latter.
Cancer Research UK reports that head and neck cancer rates in the United Kingdom have increased by more than a third since the early 1990s.
HPV, a virus that is often thought to be harmless and is transmitted through sexual contact, has been associated to a variety of malignancies, including those of the mouth, throat, and cervix.
“HPV 16 and 18 are the most common high-risk strains that can cause oropharyngeal cancer,” Mehanna added.
Laryngeal cancer, which affects the voice box, is four times more common in men and is typically diagnosed in their 60s.
Common symptoms include prolonged hoarseness, difficulty swallowing, and a lump in the neck. Early discovery can greatly improve outcomes, with survival rates of around 65% five years after diagnosis.
