Oral Sex Now Leading Cause of Throat Cancer – Experts Warn
Oral sex has emerged as the leading cause of throat cancer, with HPV infections transforming the landscape of cancer prevention
- Oral sex, particularly with multiple partners, is now the leading cause of oropharyngeal cancer
- Human papillomavirus (HPV) infections are the primary risk factor for this cancer
- HPV vaccination can prevent the majority of cases
Medical experts have now confirmed that oral sex is the primary cause of throat cancer, surpassing smoking, alcohol use, and poor diet.
The rise in oropharyngeal cancer, particularly affecting the tonsils and back of the throat, is attributed to human papillomavirus (HPV) infections, which are causing what some experts describe as an “epidemic.”
Dr. Hisham Mehanna from the University of Birmingham pointed out the alarming connection between multiple oral sex partners and an increased risk of developing this cancer.
HPV, a group of viruses linked to skin conditions, is considered the main cause of oropharyngeal cancer. While most HPV infections do not cause problems, certain strains can lead to cancer by altering the DNA of host cells. Dr. Mehanna explains that although many people clear the virus naturally, those who can’t may develop cancer over time.
The risk is especially high for those with multiple oral sex partners. Studies show that individuals with six or more lifetime oral-sex partners are 8.5 times more likely to develop oropharyngeal cancer compared to those who avoid oral sex. Despite the high rates of oral sex, only a small percentage of those infected develop the disease.
In the UK, approximately 8,300 people are diagnosed with throat cancer each year. Most cases occur in adults over 55, but 12.5% are in those under 50. HPV, transmitted through vaginal, anal, and oral sex, can be prevented through vaccination, which has proven highly effective. However, HPV vaccine coverage remains suboptimal, with fewer than 70% of adolescents receiving the full dosage.
