Treatments and drugs

By Mayo Clinic Staff

Treatment for mouth cancer depends on your cancer's location and stage, as well as your overall health and personal preferences. You may have just one type of treatment, or you may undergo a combination of cancer treatments. Discuss your options with your doctor.

Surgery

Surgery for mouth cancer may include:

  • Surgery to remove the tumor. Your surgeon may cut away the tumor and a margin of healthy tissue that surrounds it. Smaller cancers may be removed through minor surgery. Larger tumors may require more-extensive procedures. For instance, removing a larger tumor may involve removing a section of your jawbone or a portion of your tongue.
  • Surgery to remove cancer that has spread to the neck. If cancer cells have spread to the lymph nodes in your neck, your surgeon may recommend a procedure to remove cancerous lymph nodes and related tissue in the neck (neck dissection).
  • Surgery to reconstruct the mouth. After an operation to remove your cancer, your surgeon may recommend reconstructive surgery to restore the appearance of your face or to help you regain the ability to talk and eat. Your surgeon may transplant grafts of skin, muscle or bone from other parts of your body to reconstruct your face. Dental implants may replace your natural teeth.

Surgery carries a risk of bleeding and infection. Surgery for mouth cancer often affects your appearance, as well as your ability to speak, eat and swallow. Your doctor may refer you to specialists who can help you cope with these changes.

Radiation therapy

Radiation therapy uses high-energy beams, such as X-rays, to kill cancer cells. Radiation therapy can be delivered from a machine outside of your body (external beam radiation) or from radioactive seeds and wires placed near your cancer (brachytherapy).

Radiation therapy may be the only treatment you receive if you have an early-stage mouth cancer. Radiation therapy can also be used after surgery. In other cases, radiation therapy may be combined with chemotherapy. This combination increases the effectiveness of radiation therapy, but it also increases the side effects you may experience. In cases of advanced mouth cancer, radiation therapy may help relieve signs and symptoms caused by the cancer, such as pain.

Side effects of radiation therapy to your mouth may include dry mouth, tooth decay, mouth sores, bleeding gums, jaw stiffness, fatigue and red, burn-like skin reactions.

Chemotherapy

Chemotherapy is a treatment that uses chemicals to kill cancer cells. Chemotherapy drugs can be given alone, in combination with other chemotherapy drugs or in combination with other cancer treatments. Chemotherapy may increase the effectiveness of radiation therapy, so the two are often combined.

Side effects of chemotherapy depend on which drugs you receive. Common side effects include nausea, vomiting and hair loss.

Targeted drug therapy

Targeted drugs treat mouth cancer by altering specific aspects of cancer cells that fuel their growth. Cetuximab (Erbitux) is one targeted therapy approved for treating head and neck cancers in certain situations. Cetuximab stops the action of a protein that's found in many types of healthy cells, but is more prevalent in certain types of cancer cells.

Other targeted drugs are being studied in clinical trials. Targeted drugs can be used in combination with chemotherapy or radiation therapy.
