How does tongue cancer arise?

Tongue cancer usually begins in the cells covering the tongue's surface, most often on the side and front, where it can be seen and felt and is therefore caught earlier. Cancers of the tongue base tend to be diagnosed later, often once they have spread to the neck lymph nodes.

One of the first signs is a lump or sore on the side of the tongue that will not disappear. It can look pinkish red, and it may hurt or bleed when touched or bitten. Dental trauma leads the list of causes: rough teeth rubbing constantly against the edge of the tongue is among the most common. HPV, smoking and alcohol are the other main factors. Your dentist may well be the first to notice.

Treatment

Tongue cancer is a treatable cancer. The options depend on its type, location and stage. Because treatment can affect speech and swallowing, the plan is built to preserve as much function as possible.

Most tongue cancers can be removed through the mouth, using a laser where helpful. For tongue-base cancers, robotic surgery gives easier access and generally a faster recovery than standard approaches. Where the disease has spread to the neck, lymph node surgery is added. If a large part of the tongue must be removed, tissue from elsewhere in the body can rebuild it for speech and swallowing.

During surgery, pathologists confirm that all of the cancer has been removed. Radiotherapy is an option for early or advanced disease, and chemotherapy may be advised where the cancer has recurred or spread.
