Oral cancer is a broad term for cancer that affects the inside of your mouth. Oral cancer can look like a common problem on the lips or in your mouth, such as white spots or sores that bleed. The difference between a common problem and potential cancer is that these changes don't go away. If left untreated, oral cancer can spread throughout the mouth and throat to other areas of the head and neck. Approximately 63% of people with oral cavity cancer are alive five years after diagnosis.

What causes oral cancer?

Oral cancer starts in the squamous cells of your oral cavity. Squamous cells are flat and look like fish scales when viewed under a microscope. Normal squamous cells become cancerous when their DNA changes and the cells begin to grow and multiply. Over time, these cancer cells can spread to other areas inside the mouth and then to other areas of the head and neck or other areas of the body.

How do dentists diagnose oral cancer?

Oral cancer tests include:

• Physical examination: The dentist will look inside your entire mouth and may feel around your mouth. They will also examine your head, face, and neck for possible signs of precancer or cancer.
• Brush biopsy, also called scraping biopsy or exfoliative cytology: The dentist uses a small brush or spatula to gently scrape the target area to obtain cells to be examined for cancer.
• Incisional biopsy: Your dentist will remove small pieces of tissue to test the cells to check for cancer.
• Indirect laryngoscopy and pharyngoscopy: Your dentist uses a small mirror on a long thin handle to look at your throat, the base of your tongue, and part of your larynx (voice box).
• Pharyngoscopy and direct (flexible) laryngoscopy: An endoscope may be used to see areas of your throat and mouth that cannot be seen with a mirror. An endoscope is a thin and flexible tube with a light and a viewing lens attached.

• Mandibulectomy: This is surgery for oral cancer in your jawbone.
• Maxillectomy: This surgery removes part or all of the hard palate, which is the bony roof of your mouth.
• Sentinel lymph node biopsy: This test helps surgeons know if the cancer has spread beyond the original oral cancer.
• Neck dissection: This surgery is done to remove the lymph nodes from your neck.
• Reconstruction: Surgery that removes large areas of tissue may be followed by reconstructive surgery to fill gaps left by a tumor or to replace part of the lip, tongue, palate, or jaw. In some cases, reconstructive surgery is performed by removing healthy bone and tissue from other areas of your body.

What are other ways to treat oral cancer?

The dentist may combine surgery with other treatments, including:

• Radiotherapy: Radiation therapy uses strong beams of energy to kill cancer cells or prevent their growth. Your surgeon may combine radiation therapy with other treatments.
• Targeted therapy: This cancer treatment uses drugs or other substances to precisely identify and attack specific types of cancer cells without harming normal cells. Monoclonal antibodies are proteins of the immune system that are created in the laboratory and used to treat cancer.
• Chemotherapy: Your health care provider may use anticancer drugs that kill cancer cells, including treatments that affect more parts of your body.
