HPV and Throat Cancer: The Silent Risk You Shouldn’t Ignore

Most people think HPV only causes cervical cancer, but there’s another serious risk that often gets missed: HPV-related throat cancer. It’s becoming more common around the world, and in Singapore as well. A local study found that nearly 74% of oropharyngeal (throat) cancer cases were linked to HPV, and the number of cases has slowly increased in recent years. Unlike throat cancers caused by smoking or drinking, HPV-related cases often affect younger people who are otherwise healthy. Many do not show symptoms until the cancer has already grown.

In this article, we will explain how HPV can lead to throat cancer, the signs to look out for, who is at risk, and how you can protect yourself and your loved ones.

What Is HPV and How Does It Relate to Throat Cancer?

HPV (Human Papillomavirus) is a common viral infection spread through skin-to-skin contact. There are more than 100 types of HPV. While most are harmless, certain high-risk strains, especially HPV-16, can cause cancer. One of the cancers linked to high-risk HPV is oropharyngeal cancer, which affects the back of the throat, including the tonsils and the base of the tongue.

When an oral HPV infection becomes persistent, it can lead to abnormal cell changes in the throat tissue. Over time, these changes may develop into HPV-related throat cancer, particularly in people with a weakened immune system or long-term exposure to the virus.

Why Is HPV Throat Cancer on the Rise?

HPV throat cancer is one of the fastest-growing types of head and neck cancers globally. In Singapore and across Southeast Asia, health experts are reporting increased cases, particularly among non-smokers in their 30s to 50s.

What’s contributing to the rise?

Increased oral exposure to HPV due to changing sexual practices
Lack of awareness about oral HPV transmission
Limited vaccination rates in some age groups
Delayed screening for throat-related symptoms

Symptoms of HPV-Related Throat Cancer

HPV-related throat cancer often develops quietly and without obvious symptoms in the early stages, making early detection a challenge. Unlike traditional throat cancer linked to smoking and alcohol use, HPV throat cancer may not produce noticeable symptoms until the disease has advanced. Understanding the early signs of HPV-related oropharyngeal cancer can help you seek medical care sooner and improve treatment outcomes.

Common symptoms of HPV-related throat cancer include:

Persistent sore throat that lasts longer than two weeks
Difficulty swallowing or feeling like something is stuck in your throat
Swollen lymph nodes or lumps in the neck that do not go away
Ear pain without any signs of infection or ear problems
Hoarseness or changes in your voice that last for more than a couple of weeks
A lump in the throat or neck that feels firm and persists

Because these symptoms can be caused by less serious conditions, they are often overlooked. However, if any of these signs last longer than two weeks, it’s important to consult a healthcare professional promptly for evaluation.

Who Is at Risk of HPV Throat Cancer?

Anyone exposed to high-risk HPV strains is at risk. However, certain groups may face a higher chance of developing HPV oral cancer:

Individuals with multiple oral sex partners
Men over 40 (more affected than women)
People with weakened immune systems
Individuals not vaccinated against HPV

In Singapore, awareness of HPV-related throat cancer is still low. Many do not know that oral HPV can be transmitted without penetrative sex, and that it may take years before any symptoms develop.

How Is HPV Throat Cancer Diagnosed in Singapore?

In Singapore, there is currently no standard screening test available for oral HPV infection or HPV-related throat cancer. Unlike cervical cancer, where regular HPV and Pap smear screening programs are well established, screening for oral and throat HPV infections is not yet part of routine health checks.

Diagnosis of HPV-related throat cancer typically happens only after patients report persistent symptoms, such as a sore throat or lumps in the neck. Healthcare professionals may use several diagnostic tools to confirm the presence of cancer:

Physical examination of the mouth and throat by an ENT specialist
Endoscopic examination to view deeper areas of the throat and oropharynx
Biopsy of any suspicious lesions or lumps to test for cancer cells
Imaging tests such as MRI or CT scans to evaluate the extent of the cancer

Residents in Singapore are encouraged to be aware of the symptoms and seek timely medical advice if symptoms last longer than two weeks.

Can HPV Vaccination Prevent Throat Cancer?

Yes, vaccination plays a crucial role in preventing HPV-related cancers. The HPV vaccine, such as Gardasil 9, protects against multiple high-risk HPV strains, including HPV-16, which is most commonly linked to throat cancer.

In Singapore, the HPV vaccine is available and recommended for all individuals. It is most effective when given before exposure to the virus, typically between ages 9 and 26. However, adults up to age 45 may still benefit from vaccination.

Encouraging HPV vaccination for all individuals is one of the most effective ways to reduce future cases of HPV-related cancers.

Simple Ways to Lower Your Risk of HPV Throat Cancer

You can take several practical steps to reduce your risk of oral HPV infection and the possibility of developing HPV oral cancer:

Get vaccinated early
Limit number of sexual partners
Use protection during oral sex
Avoid tobacco and excessive alcohol
Maintain regular dental check-ups
Seek prompt medical care for any throat or mouth abnormalities

Prevention starts with awareness. Many people in Singapore still think HPV only affects women or causes cervical cancer. However, HPV can affect individuals of all genders, so it’s important that everyone understands the wider health risks.

Speak to a Specialist About HPV Concerns

HPV and throat cancer may not get as much attention as other cancers, but they are serious health concerns in Singapore. As awareness grows, it is important to take proactive steps such as getting vaccinated, speaking to a medical professional about symptoms, or helping others learn about prevention. If you have questions about HPV, its link to throat cancer, or how it could affect you or your partner, do not leave your health to chance. Early evaluation and timely guidance can make all the difference.
