Mouth cancer can appear on the lips or anywhere in the mouth, including the tissues inside the cheeks, the tongue, and the gums. Mouth cancer may look like red, gray, or white patches of skin, thick growths, or sores that do not heal with time.
Mouth cancer is a type of head and neck cancer, and it often comes under the category of oral and oropharyngeal cancer.
Oral cancer is cancer that starts in the mouth, or oral cavity, which includes the:
- tongue lining
- inside of the cheeks
- hard palate (the bony roof of the mouth)
- floor of the mouth below the tongue
Cancer occurs when cancerous cells begin to reproduce and grow out of control. Cells virtually anywhere in the body may become cancerous, and the growth of cancerous cells may spread to other areas of the body.
Some signs of precancerous conditions may be indicators to see a doctor. In many cases, a person may have no noticeable symptoms at first.
In this article, we discuss the appearance of mouth cancer, its symptoms, and how to differentiate it from other conditions.
Research suggests that
As cancer develops and progresses, a person may notice symptoms such as:
- bleeding and pain in the mouth
- numbness in one or more areas of the mouth
- a lump or buildup of tissue in the gums
- sore throat
- loose teeth
- red and white patches on the mouth or tongue
- difficulty moving the tongue or chewing
- discomfort or difficulty while chewing or swallowing
Oral cancer may appear differently based on its stage, location in the mouth, and other factors. Oral cancer may present as:
- patches of rough, white, or red tissue
- a hard, painless lump near the back teeth or in the cheek
- a bumpy spot near the front teeth
- growths of tissue on the roof of the mouth
- open, oozing sores in the mouth that do not go away with time
- bright red patches on the tongue
- tissue turning gray or white
- numbness in the tongue
Dysplasia is a term that refers to the abnormal development of cells in tissues or organs. In adults, an increase in abnormal cell growth may suggest precancer.
Possible precancerous conditions for oral cancer may
- Leukoplakia: These are white or gray patches in the mouth that do not go away when a person rubs them.
- Erythroplakia: These are flat or slightly raised areas of tissue that are often red and may bleed easily on scraping.
- Erythroleukoplakia: A combination of the two, this is a patch of tissue with both red and white areas.
Smoking and chewing tobacco are the most common causes of these conditions. Dysplasia will often go away if a person removes the causes, but there is not always a clear cause.
A biopsy is the only way to know whether the tissue contains precancerous or cancerous cells.
Most cases of leukoplakia do not develop into cancer. Erythroplakia and erythroleukoplakia are less common but usually more serious. Many of these lesions progress into cancer.
However, it is important to note that most oral cancers do not develop from preexisting lesions.
There are several types of oral lesions that can be concerning but are not signs of cancer.
Canker sores typically heal naturally within 2 weeks, whereas cancerous lesions do not go away with time.
Working with a healthcare professional may help a person identify their triggers of canker sores so that they can avoid them where possible.
Oral lichen planus is chronic inflammation in the mucous membranes in the mouth. It causes white, lacy markings in the mouth, which are not similar to the patchy white marks of leukoplakia.
There is still debate regarding the association between lichen planus and cancer. However,
Anyone with lichen planus should check in with their healthcare professional often for checkups and treatment.
Some benign or noncancerous tumor-like growths may also occur in the mouth, including:
These noncancerous tumors and growths occur due to variations in different cells, and they have a variety of causes. While some
Anyone who is uncertain about their symptoms should see a healthcare professional if only to provide peace of mind. They may perform a physical exam to check for noticeable features of cancer. If necessary, they will order diagnostic tests.
Anyone with concerning symptoms, such as trouble chewing, swallowing, or breathing, should see a doctor immediately. Although cancer is not the only cause of these symptoms, they are concerning signs of an underlying issue.
Additionally, anyone noticing patches of tissue or growths in the mouth that do not go away with time should see a healthcare professional.
Here are some answers to questions people often ask about mouth cancer:
What are the signs of cancer in the mouth?
Signs of cancer in the mouth include rough patches and painless bumps, lumps, or other tissue growths. People may also experience tissue of the mouth turning white, red, or gray. Mouth cancer may also involve open, oozing sores that do not seem to heal.
How long can you survive untreated mouth cancer?
Whether or not a person has treatment for mouth cancer, various factors will affect the outlook. They include the stage at diagnosis, where the cancer starts, and other factors.
Overall, there is a
If cancer that starts on the lip spreads to other parts of the body, however, the chance of surviving falls to 38%. If cancer starts on the floor of the mouth, the overall chance of survival for 5 years or longer is 53%, according to the American Cancer Society.
Is mouth cancer curable?
Treatment includes surgery, radiation therapy, and chemotherapy. The choice will depend on the individual and the stage of cancer. It is often effective. For people with early-stage mouth cancer that starts on the lip, there is a
Mouth cancer usually presents with distinctive symptoms and features, such as red or white patches in the mouth, changes in oral tissue, or difficulty chewing or swallowing.
While these symptoms are not unique to oral cancer, if they are persistent and do not heal over time, they may indicate cancer.
If people notice these or other concerning symptoms, they should see a healthcare professional. Early diagnosis provides a higher chance of successful treatment.
