New Research Makes Shocking Link Between Sex And Some Cancers
A new study has pointed at a direct link between sex and some rising cases of cancer, especially throat cancer.
GWG.ng reports that Dr Hisham Mehanna, from the UK’s University of Birmingham, said 70 percent of cases of throat cancer are caused by human papillomavirus (HPV), a normally harmless virus that is spread sexually and has been linked to multiple forms of cancers.
Multiple oral sex partners, according to Dr. Mehanna, can increase the risk of throat cancer by up to nine times.
He wrote in The Conversation: ‘Over the past two decades, there has been a rapid increase in throat cancer in the west, to the extent that some have called it an epidemic.
‘This has been due to a large rise in a specific type of throat cancer called oropharyngeal cancer. Oropharyngeal cancer is the most common type of throat cancer. It appears in the tonsils and back of the throat.
‘Those with six or more lifetime oral-sex partners are 8.5 times more likely to develop oropharyngeal cancer than those who do not practice oral sex.’
More than 50,000 cases of oral or oropharyngeal cancer are diagnosed in the US each year, causing more than 10,000 annual deaths.
The number of cases is growing, however, up to 1.3 percent a year in women and 2.8 percent in men, according to the American Cancer Society.
Scientists at NYU Langone estimate that as much as 70 percent of throat cancer cases are caused by HPV infections, furthering the link between the cancers and sex. In the UK, head and neck cancers combined are responsible for more than 12,000 cases and 4,000 deaths per year.
