Cancer of the Floor of the Mouth
Cancer of the floor of the mouth is a type of oral cancer that occurs in the floor of the mouth, which is the area under the tongue and behind the lower teeth. It is a rare type of cancer, accounting for about 2-4% of all oral cancers.
Causes and Risk Factors
The exact cause of cancer of the floor of the mouth is not known, but several risk factors have been identified, including:
- Tobacco use: Smoking and chewing tobacco are major risk factors for developing oral cancer, including cancer of the floor of the mouth.
- Alcohol consumption: Heavy drinking can increase the risk of developing oral cancer.
- Human papillomavirus (HPV) infection: HPV is a virus that can cause changes in the cells of the mouth and throat, leading to cancer.
- Poor diet: A diet low in fruits and vegetables may increase the risk of developing oral cancer.
- Genetic predisposition: Some people may be more likely to develop oral cancer due to their genetic makeup.
Symptoms
The symptoms of cancer of the floor of the mouth can vary, but may include:
- A lump or sore in the floor of the mouth that does not heal
- Pain or discomfort in the mouth or tongue
- Difficulty speaking or swallowing
- Numbness or tingling in the mouth or tongue
- Loose teeth or dentures that no longer fit properly
- Weight loss or fatigue
Diagnosis
Cancer of the floor of the mouth is typically diagnosed through a combination of physical examination, imaging tests, and biopsy. The diagnostic process may include:
- Visual examination: A doctor will examine the mouth and tongue to look for any visible signs of cancer.
- Imaging tests: X-rays, CT scans, or MRI scans may be used to determine the extent of the cancer and whether it has spread to other parts of the body.
- Biopsy: A sample of tissue is removed from the suspected tumor and examined under a microscope for cancer cells.
Treatment
The treatment for cancer of the floor of the mouth depends on the stage and location of the cancer, as well as the overall health of the patient. Treatment options may include:
- Surgery: The tumor is removed surgically, along with a margin of healthy tissue.
- Radiation therapy: High-energy rays are used to kill cancer cells.
- Chemotherapy: Medications are used to kill cancer cells.
- Targeted therapy: Medications that target specific molecules involved in cancer growth and development are used to treat the cancer.
Prognosis
The prognosis for cancer of the floor of the mouth varies depending on the stage and location of the cancer, as well as the overall health of the patient. Early-stage cancers that are caught and treated promptly have a better prognosis than more advanced cancers.
Prevention
While there is no guaranteed way to prevent cancer of the floor of the mouth, there are several steps that can be taken to reduce the risk:
