In recent years, media outlets have warned that oral sex is fueling a “throat cancer epidemic” — some even claim it’s already more common than cervical cancer. That sounds like an alarm bell rung too loudly. So what does the science actually say? Let’s dive deep, backed by data.
🔬 The Biological Link: HPV, Oral Sex & Throat Cancer
- The human papillomavirus (HPV), especially high-risk strains like HPV-16, is firmly linked to oropharyngeal (throat) cancers.
- Oral sex is a documented route for transmitting HPV to the throat.
- In high-income countries, the share of throat (oropharyngeal) cancers that are HPV-driven has grown. In the U.S., ~60–70% of oropharyngeal cancers are now attributed to HPV.
- In the UK, ~51.8% of oropharyngeal squamous cell carcinoma (OPSCC) cases (2002–2011) were HPV-positive, and the overall incidence of OPSCC roughly doubled in that decade.
📈 Incidence Trends & Comparisons
United States
- Among HPV-related cancers, oropharyngeal cancers now outnumber cervical cancers.
- The incidence of HPV-positive oropharyngeal cancer in the U.S. has surged — some studies show ~225% increase over certain decades.
- For context, lifetime risk (oral cavity + throat) is ~1 in 59 for men, ~1 in 139 for women in the U.S.
United Kingdom
- In 2019 in England, 3,834 new oropharyngeal cancer cases were recorded — up ~47% since 2013.
- Head & neck cancer diagnoses in the UK (~12,200 per year) have been rising, driven primarily by oropharyngeal cancers.
- By contrast, cervical cancer in the UK is ~3,300 new cases per year (2017–2019).
Despite strong upward trends in throat cancer, cervical cancer in women remains a significant burden. It has also benefited from screening and vaccination efforts, causing its incidence to decline in many places.
⚖️ “Epidemic” or Not? Weighing the Word
“Epidemic” is dramatic. The rise in HPV-related throat cancers is real and concerning, but it has unfolded over years, not overnight. The shift is more of a slow-burning change in cancer epidemiology than a sudden explosion.
💡 So, Are Those Bold Claims Accurate?
Claim | Assessment |
Claim | Assessment |

Assessment |
|
“Oral sex is causing a throat cancer epidemic†|
Partially true — HPV via oral sex is a key driver of the rise in HPV-positive throat cancers, but not all throat cancers. |
|
“More damaging than smoking, boozing, bad diet†|
Overstated — smoking and alcohol remain major players, especially for HPV-negative cancers. |
|
“Now more common than cervical cancer†|
Valid within HPV-related cancers (in the U.S.) but too broad when generalized across all cancers. |
Bottom Line
It’s not just clickbait: there is a serious and growing problem. HPV-driven throat cancers are on the rise, and in certain settings and demographics they now outstrip cervical cancers in terms of HPV-related incidence. But many claims blur important distinctions. The rise is real, but context matters.
📣 What You Can Do & What to Watch
- Promote HPV vaccination (recommended for both sexes) — it prevents the high-risk types.
- Maintain safer sex practices and be aware of HPV transmission routes.
- Don’t skip screening programs (e.g. cervical screening in women) — they remain vital.
- Stay updated on new research; this is an evolving field.
