Oral cancer: symptoms everyone should know

Oral cancer symptoms don’t always stand out right away. A sore that lingers, throat pain and trouble swallowing can feel like something minor at first. The key is how long the change lasts and whether it keeps coming back.

If you notice a change in your mouth, lips or throat that lasts more than two weeks, it’s time to make an appointment with a dentist or doctor. Most symptoms have causes that are not caused by cancer but still deserve attention. Getting checked can help you get the right care sooner.

What is oral cancer?

Oral cancer is cancer that starts in the mouth or the back of the throat. It can develop on the lips, tongue, gums, lining of the cheeks, floor of the mouth, roof of the mouth, tonsils or the throat area behind the mouth. It’s more common in people over 40, but it can happen at other ages.

Oral cancer symptoms are usually not painful or dramatic, especially during early stages. That’s why regular dental visits are important: they give your dentist a chance to check for changes you may not feel yourself.

Oral cancer symptoms and warning signs

Every case of oral cancer doesn’t look the same. Some signs are visible, while others feel more like a sore throat, ear pain or trouble swallowing. Pay attention to symptoms that do not improve, including:

• Sore or lump. A sore, irritation, lump or thick patch in the mouth, lip or throat.
• Red or white patch. A red or white patch inside the mouth.
• Throat changes. A sore throat, hoarseness or feeling that something is caught in the throat.
• Swallowing trouble. Trouble with chewing, swallowing or speaking.
• Numbness or pain. Numbness, pain or bleeding in the oral cavity.
• Jaw changes. Swelling in the jaw that may make dentures fit poorly or feel uncomfortable.

Mouth sores, red patches and white patches

Mouth sores are common and usually heal, but a sore that doesn’t heal is different. If a sore, lump, thick patch, red patch or white patch lasts more than two weeks, make an appointment with a dentist or doctor. You should also get care for a sore that bleeds, keeps coming back, causes numbness or makes chewing, swallowing or speaking difficult.

Oral cancer causes and risk factors

Tobacco use is a major risk factor for oral cancer. This includes cigarettes, cigars, pipes, chewing tobacco, snuff and electronic cigarettes. Heavy alcohol use also raises risk, especially when combined with tobacco use.

Human papillomavirus (often called HPV) is also linked to many cancers in the back of the throat, and sun exposure can raise the risk of cancer on the lips. Risk also increases with age, so it’s best to speak with your doctor about your situation as the years go by.

Oral cancer screening and dental checkups

An oral cancer exam is usually quick and painless. During the exam, a dentist, dental hygienist or doctor may check your face, neck, lips, mouth and throat area for possible signs of cancer. A regular dental checkup is a good time to ask about an oral cancer exam, but if you have symptoms that worry you, don’t wait for your next scheduled checkup.

Risk reductions and oral cancer prevention

Some risk factors cannot be changed, but you can lower your risk in a few ways. Avoid tobacco in all forms, limit alcohol use and protect your lips from sun exposure. You can also ask your doctor whether the HPV vaccination is right for you or your child.

If you notice a mouth or throat change that does not go away, bring it up with your dentist or family physician. You don’t have to know if it’s serious before asking. A quick conversation can help you understand what’s happening and what to do next.
