What kind of doctor treats Tongue Cancer?
Tongue cancer is usually treated by a head and neck surgeon or an otolaryngologist, an ear, nose, and throat doctor. Cancer doctors called medical and radiation oncologists also treat oral cancer. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is tongue cancer?
Tongue cancer is cancer that starts in the tongue. It is a kind of oral cancer, which means cancer of the mouth. The front two-thirds of the tongue is part of the mouth, called the oral cavity. The back third is called the base of the tongue and is part of the throat, called the oropharynx.
Almost all cancers in the mouth and throat are squamous cell carcinomas. These start in squamous cells, which are flat, thin cells that line the mouth and throat. Most facts here come from information about oral cancer, which includes cancer of the tongue.
Symptoms
See a dentist or a doctor if you have any of these signs for more than two weeks:
- A sore, irritation, lump, or thick patch in your mouth, lip, or throat.
- A white or red patch in your mouth.
- Trouble chewing, swallowing, or speaking.
- Trouble moving your jaw or tongue.
- Numbness in your tongue or other parts of your mouth.
- Pain or bleeding in the mouth.
- A lump in the neck.
- Ear pain.
A white or red patch can be cancer, a pre-cancer change called dysplasia, or just a harmless change.
Causes and who gets it
Most cancers in the mouth are related to tobacco use, drinking alcohol, or both. Tobacco of any kind raises the risk, including cigarettes, pipes, cigars, e-cigarettes, chewing tobacco, and snuff. Heavy alcohol use also raises the risk. Using both raises it even more.
Oral cancers most often happen in people over the age of 40. They affect more than twice as many men as women. A diet low in fruits and vegetables has been linked to a higher risk. HPV, the human papillomavirus, is mostly linked to cancer at the back of the tongue and rarely to cancer of the mouth, including the front of the tongue.
How doctors diagnose it
A dentist or dental hygienist can check for early signs of oral cancer during a regular checkup. They look at your face, neck, lips, mouth, and the back of the throat. If something looks unusual, you may need more tests or a visit to a specialist.
A biopsy is the only way to know for certain if a patch has cancer cells. In a biopsy, a doctor takes a small piece of tissue to check for cancer cells.
Treatment
Surgery is the main treatment for cancer in the front of the tongue. The surgeon may also remove some lymph nodes in the neck to check them for cancer spread. Radiation may be added after surgery if the cancer might not have been fully removed or could come back.
For early cancers, surgery and radiation work equally well. The choice depends on your wishes and on side effects, such as how treatment might change the way you look, swallow, and speak. Radiation is often used instead of surgery for people who cannot have surgery because of other health problems.
Bigger cancers may need more than one treatment. These can include chemotherapy, which is cancer-killing medicine, targeted therapy, and immunotherapy, which helps the body's defenses fight cancer. Your care team may also include dentists, speech pathologists, dietitians, and counselors. See a dentist about a month before treatment if you can, so your mouth has time to heal after any dental work.
When to see a doctor
See a dentist or a doctor if a sore, lump, patch, numbness, or trouble moving your tongue lasts more than two weeks.
Call 911 or go to the emergency room if you have trouble breathing, are choking, have bleeding that will not stop, or have sudden swelling of the face or tongue.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can examine your mouth, ask about your symptoms and tobacco and alcohol use, and send you quickly to a dentist or a head and neck specialist. They can also help coordinate care and follow-up.
Common questions
What are the signs of tongue cancer?
Signs can include a sore, lump, or thick patch in your mouth, or a white or red patch. Numbness in the tongue or trouble moving it can also happen. See a dentist or doctor if any sign lasts more than two weeks.
Does smoking cause tongue cancer?
Smoking raises the risk of oral cancers, including cancers that start on the tongue. Tobacco use of any kind puts you at risk for oral cancers, and oral cancers can develop on the tongue. Using both tobacco and alcohol raises the risk even further.
Is HPV linked to tongue cancer?
HPV is mostly linked to cancer at the back of the tongue. In the United States, most squamous cell cancers of the oropharynx, which includes the back third of the tongue, are caused by certain high-risk types of HPV. HPV is rarely linked to cancers of the mouth, which includes the front of the tongue.
How is tongue cancer treated?
Surgery is the main treatment for cancer in the front of the tongue. Radiation, chemotherapy, targeted therapy, or immunotherapy may be added or used instead, depending on the stage and your health.
