Treatments for early-stage oral cancer

The following are treatment options for early-stage (stage 1 and stage 2) oral cancer. Your healthcare team will suggest treatments based on your needs and work with you to develop a treatment plan.

Surgery is the main treatment for early-stage oral cancer. The type of surgery done depends on where the cancer is in the mouth.

The following procedures are commonly used to treat early-stage oral cancer.

A wide local excision removes the tumour and a small amount of healthy tissue with it (called the surgical margin). The size and depth of the surgical margin depends on the location of the tumour.

A glossectomy removes the tumour and part or all of the tongue.

A neck dissection removes lymph nodes from the neck. It may be done to check if the cancer has spread to the lymph nodes.

A sentinel lymph node biopsy (SLNB) finds and removes the first lymph node (sentinel lymph node) in a group of lymph nodes to see if it contains cancer cells.

Reconstructive surgery may be needed to rebuild the part of the mouth where a large tumour has been removed. A skin graft (skin from another part of the body) or a flap (skin, muscle, bone or a combination of these from another part of the body) may be used in the reconstruction.

Radiation therapy uses high-energy rays or particles to destroy cancer cells. Early-stage oral cancer is sometimes treated with external radiation therapy, which uses a machine outside the body to direct a beam of radiation through the skin to a specific part of the body.

You may have radiation therapy after surgery that removes an early-stage oral cancer.

Talk to your doctor about clinical trials open to people with oral cancer in Canada. Clinical trials look at new ways to prevent, find and treat cancer. Find out more about clinical trials.
