Floor of the mouth cancer affects the bottom of your mouth under your tongue. The most common type of floor of the mouth cancer is squamous cell, affecting the cells that line the mouth and throat (oral cavity). Changes in the look and feel of the soft tissue on the floor of your mouth, such as a lump or a sore that doesn't heal, may indicate cancer. Tobacco and heavy alcohol use increase your risk of floor of the mouth cancer.

Why Choose Mayo Clinic
What Sets Mayo Clinic Apart
Mayo Clinic doctors use highly advanced diagnostic services to identify floor of the mouth cancer. The process starts with a physical exam and a discussion of your symptoms and medical history.
Your doctor may take a small sample of tissue (biopsy) to send to the lab for analysis. X-rays help locate abnormalities in the floor of your mouth and jaws. Your doctor may order other imaging tests, such as those below, to determine if the cancer has spread. In tests that involve radiation, Mayo Clinic specialists carefully monitor doses to avoid the risk of radiation overexposure.
- Computerized tomography (CT). CT scans generate 2-D images of the head and neck that may reveal whether cancer has invaded other tissues or organs.
- Magnetic resonance imaging (MRI). An MRI uses a magnetic field and radio waves to identify small abnormalities in the head and neck in 3-D views and to determine if cancer has spread to other organs.
- Positron emission tomography (PET) scans. PET scans use a small amount of radioactive materials to identify cancer and to determine if it has spread to lymph nodes or other organs in the body such as the lungs, liver or bones.
Mayo Clinic doctors use the latest technology and techniques to treat floor of the mouth cancer. Treatment may include surgery, radiation therapy, chemotherapy, reconstructive surgery or a combination of these approaches. A multidisciplinary team trained in ear, nose and throat (ENT), oral and maxillofacial surgery, radiation oncology, medical oncology, plastic and reconstructive surgery, and other specialties provides you with optimal treatment for floor of the mouth cancer.
- Surgery. The type of surgery used to treat floor of the mouth cancer depends on the size, type, location and depth of the tumor spread. If the tumor has spread beyond the floor of the mouth, nearby lymph nodes may need to be removed and examined in a laboratory.
- Radiation therapy. Radiation therapy uses high-energy X-rays, electron beams or radioactive isotopes to kill cancer cells. At Mayo Clinic, you have access to the most advanced therapy, including intensity-modulated radiation therapy (IMRT). Radiation oncologists tailor each treatment to protect nearby normal tissue.
- Chemotherapy. Chemotherapy uses drugs to destroy cancer cells. For floor of the mouth cancer, experienced medical oncologists may administer chemotherapy orally or into your veins.
- Reconstructive surgery. Depending on the size, location and spread of the cancer, some people may need reconstructive surgery to restore physical appearance and mouth function.
- Rehabilitation. Rehabilitation specialists in speech therapy, swallowing therapy, dietetics, physical therapy and occupational therapy help with rehabilitation that may be necessary after surgery or radiation therapy.
