What kind of doctor treats Erythroplakia?

A dentist or an ear, nose, and throat doctor (an otolaryngologist, a doctor who treats the mouth and throat) usually looks after erythroplakia. 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 erythroplakia?

Erythroplakia is a flat or slightly raised red area in the mouth or throat that often bleeds easily when scraped. It is listed as a possible pre-cancer condition. A pre-cancer condition is a change that may turn into cancer later.

A red patch may be cancer, a pre-cancer condition called dysplasia, or just a harmless change. Dysplasia means the cells look abnormal under a microscope. Erythroplakia is less common than leukoplakia, a white or gray area that does not come off when scraped, but it is usually more serious.

Symptoms

Erythroplakia shows up as a red patch. It often bleeds easily when scraped. A patch with both red and white areas is called erythroleukoplakia.

The American Cancer Society lists a white or red patch on the gums, tongue, tonsil, or lining of the mouth as a possible sign of mouth and throat cancer. It also lists these signs:

  • A sore on the lip or in the mouth that does not heal.
  • Pain in the mouth that does not go away.
  • A lump or thickening in the lips, mouth, or cheek.
  • Trouble chewing or swallowing.

Many of these signs can also be caused by other diseases.

Causes and who gets it

Smoking and chewing tobacco are the most common causes of these red and white patches. Poorly fitting dentures that rub against the tongue or the inside of the cheeks can also cause these changes. Sometimes there is no clear cause.

Tobacco use and heavy alcohol use raise the risk of mouth and throat cancers.

How doctors diagnose it

A dentist or dental hygienist may be the first person to find these patches. A biopsy is the only way to know for certain if one of these patches has cancer cells or pre-cancer cells. In a biopsy, a doctor takes a small sample of tissue to look at in a lab. Other tests might be done first to help decide if a biopsy is needed or to choose the best area to sample.

Dysplasia can be mild, moderate, or severe. Severe dysplasia is more likely than mild dysplasia to become cancer.

Treatment

Doctors often remove these areas, especially if a biopsy shows dysplasia, which means abnormal cells. Dysplasia sometimes goes away if the cause is removed, such as poorly fitting dentures.

Removing these areas does not always keep someone from getting oral cavity cancer. Even after the areas are removed, some people still have a higher chance of cancer in another part of the mouth. People who have had these areas removed should keep getting regular check-ups for cancer and for new patches.

Quitting tobacco is an important step. Quitting tobacco greatly lowers the risk of mouth and throat cancer, even after many years of use.

When to see a doctor

See a dentist or doctor soon if you find a red patch in your mouth, and do not wait to see if it goes away. If a mouth sore or pain in the mouth lasts more than a few weeks, it is also very important to see a doctor or dentist. Trouble chewing or swallowing is also a sign to have checked. So is a lump or thickening in the lips, mouth, or cheek.

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. A direct primary care or concierge doctor can look at the patch, ask about tobacco and alcohol use, and refer you to a dentist or an ear, nose, and throat doctor for a biopsy. They can also help you keep up with follow-up visits.

Common questions

Is erythroplakia cancer?

It can be, but not always. A red patch may be cancer, a pre-cancer condition called dysplasia, or just a harmless change. A biopsy is the only way to know for certain.

Is erythroplakia more serious than leukoplakia?

Yes, it is usually more serious. Red patches are more likely than white patches to be cancer or to turn into cancer later.

Can erythroplakia go away?

Sometimes the abnormal cells in a patch go away if the cause is removed, such as poorly fitting dentures. But do not wait for a red patch to go away, because a biopsy is the only way to know what the cells in a patch look like.

Does removing the patch prevent mouth cancer?

No, not always. Removing these areas does not always keep someone from getting oral cavity cancer. Regular check-ups are still needed after the patch is removed.

Who is usually the first to notice erythroplakia?

A dentist or dental hygienist may be the first person to find it.
