Throat cancer can develop unnoticed for years—sometimes even decades—before producing a clear warning.

When symptoms do appear, they may seem routine: a sore throat that will not go away, trouble swallowing, a shift in the voice or a painless lump in the neck.

For much of the past, throat cancer was linked mainly to older adults with long histories of smoking or heavy alcohol use.

Yet as smoking and alcohol consumption have declined, doctors have begun to see a different pattern.

More patients now have never smoked, drink little or no alcohol and lack the traditional risk factors associated with the disease.

The change has been especially evident in cancers of the tonsils and the base of the tongue, known collectively as oropharyngeal cancer.

A common sexually transmitted infection—human papillomavirus, or HPV—is behind much of that increase.

Most people encounter the virus at some point in their lives.

HPV is estimated to cause between 60 and 70 percent of oropharyngeal cancers in the US.

Although most patients are diagnosed in middle or older age, the infection may have been acquired decades before the cancer appears.

Researchers are also examining whether modern exposures—including vaping, ultra-processed foods, air pollution and microplastics—could influence the risk of head and neck cancers, a wider category that includes tumors of the throat, mouth, nose and voice box.

So what is driving America’s changing throat cancer landscape? Who faces the greatest risk, and what steps can people take to lower it? What is throat cancer—and how deadly can it be? Throat cancer is not one single condition.

It falls within the broader group of head and neck cancers, which can begin in the mouth, throat, nose, sinuses or voice box.

The likely causes, treatment options and survival rates vary considerably according to the cancer’s location.

In 2026, an estimated 72,770 people in the US will be diagnosed with cancers of the mouth, throat or voice box, while approximately 17,110 are expected to die from the disease.

The prognosis depends heavily on when the cancer is found.

About 86 percent of people with early-stage oropharyngeal cancer—before it has spread beyond its original site—survive at least five years.

That figure falls to about 40 percent when the disease is diagnosed at an advanced stage.

Dr Selda Samakoglu, an oncologist at Aveta Biomics who specializes in head and neck cancer, said: ‘Over many years, high-risk types can disrupt normal cell growth and eventually cause cancer in the tonsils or at the base of the tongue.’ Studies have also associated having more oral sex partners with a greater risk of HPV-related throat cancer.

Still, most people exposed to HPV will never develop the disease.

There is one important form of protection: vaccination.

The HPV vaccine was first introduced for girls in the US in 2006, followed by routine vaccination recommendations for boys in 2011.

Its effects have already been substantial.

HPV causes nearly all cervical cancers as well.

Since vaccination began, rates of precancerous changes in cervical cells among young American women have dropped by almost 80 percent.

The outlook for throat cancer is also encouraging.

A recent US study of 1.4 million people found significantly fewer head and neck cancers among those who had received the HPV vaccine.

Experts expect the vaccine’s protective effect to become clearer over the next several decades, as vaccinated generations reach the ages when these cancers are most likely to develop.

‘The vaccine’s full benefit should become more apparent as vaccinated generations grow older,’ Samakoglu said.

Genes are only part of the picture Throat cancer can occur in families, but inherited genetic factors are believed to explain only a small share of cases.

Having a parent, sibling or child with head and neck cancer is linked to an approximately 70 percent higher risk of developing the disease.

Researchers think genetic differences may leave some people more vulnerable to environmental exposures by affecting how their bodies process harmful substances or repair damaged DNA.

‘Genes can also influence how the body responds to different exposures,’ said Dr Selda Samakoglu, an oncologist specializing in head and neck cancer, in an interview with Our News Outlet.

Rare inherited disorders, including Fanconi anemia, can sharply raise the risk of certain head and neck cancers because they impair the body’s ability to repair DNA damage.

Smoking is falling—but vaping raises new questions Smoking has traditionally been one of the leading causes of throat cancer.

Tobacco smoke contains dozens of carcinogenic chemicals that can damage DNA in cells lining the throat, allowing tumors to form over time.

However, cigarette use has fallen sharply in the US, particularly among younger adults.

At the same time, vaping has grown more popular, prompting concerns about whether e-cigarettes could create a comparable cancer risk.

Unlike smoking, the long-term health consequences of vaping are still unclear.

E-cigarettes have been widely used for only about two decades, so researchers have not yet determined whether they increase the risk of throat cancer.

Early findings, however, have raised concerns.
