Oral Sex and Cancer Risk: What You Need to Know
Recent studies have shown that people who engage in oral sex are over eight times more likely to develop oral or oropharyngeal cancer, with the primary culprit being human papillomavirus (HPV) — one of the most widespread sexually transmitted infections globally.
According to Dr. Hisham Mehanna, a leading professor at the University of Birmingham, the sharp increase in throat cancer cases over the past two decades has reached alarming levels. He describes it as an “epidemic” — and one that is being driven not by traditional risk factors like smoking or alcohol, but by oral sex and the number of sexual partners a person has had over their lifetime.
HPV is usually cleared naturally by the immune system. However, in some people, the virus persists in the throat and can, over time, trigger cellular changes that lead to cancer — especially oropharyngeal cancers, which affect the tonsils and the base of the tongue.
Key Factors That Increase Risk:
-
Having a high number of oral sex partners over a lifetime.
-
Smoking and heavy alcohol consumption, which can weaken immune defenses.
-
A poor diet, especially one lacking fruits and vegetables that support immunity.
How to Reduce Your Risk:
-
Limit the number of sexual partners, especially unprotected oral sex.
-
Consider getting the HPV vaccine (recommended for both men and women, ideally before becoming sexually active, but beneficial even later).
-
Maintain a healthy diet rich in antioxidants.
-
Avoid or quit smoking and excessive alcohol use.
HPV-related cancers often do not show symptoms until they are advanced, making prevention and awareness critical. If you experience persistent sore throat, difficulty swallowing, or a lump in the neck, consult a healthcare provider.
