While some issues in and around the mouth may not be a cause for concern, contact a doctor or dentist if you have any of these symptoms for longer than 2 weeks:
- a sore throat or feeling that something is caught in your throat

The exact causes of mouth cancer are unknown, but the following risk factors increase your chances of mouth cancer developing:
- Smoking: Most mouth cancers are related to or tobacco use. Any form of tobacco use will increase your risk of oral cancer. It’s estimated that about 90% of mouth cancers worldwide are due to tobacco use, alcohol consumption, or a combination of both.
- Alcohol use: Heavy alcohol use is known to increase your risk. Heavy smoking and drinking combined will increase that risk further.
- HPV: Infection with some forms of HPV
can causemouth cancers.
- Age: People over 40 have a higher risk of mouth cancer.
- Sun exposure: Too much sun exposure can also increase your mouth cancer risk.
- Being male: People assigned male at birth are almost
twiceas likely to get oral cancer.
Treatment depends on the cancer’s stage and the area of the mouth or throat that is affected. Generally, treatment options include:
- Surgery: Surgery to remove cancerous areas is usually an initial treatment for all mouth cancers. In early stage or small cancers, this may be the only treatment needed. Depending on how large an area is removed, reconstructive surgery may also be needed.
- Radiation therapy: Sometimes radiation therapy alone is used for small mouth cancers, such as in the lip area. It’s also used after surgery or along with chemotherapy to prevent recurrence or help manage later stage cancers.
- Chemotherapy: Chemotherapy may be used alone or combined with radiation in later stage mouth cancers.
- Clinical trials: Many
experts suggestthat people with head and neck cancers consider a clinical trial, to possibly take advantage of newer treatments.
Mouth cancer is most treatable when diagnosed and addressed in an early stage. The type of mouth and throat cancer will also factor into the long-term outlook.
- the cancer’s stage at diagnosis
- a person’s age and overall health
- the type of cancer you have
- your cancer’s general response to treatment.
