Symptoms of mouth cancer

Mouth cancer or cancer of the oral cavity is a relatively uncommon cancer in the United Kingdom and a more common cancer in some parts of the world like Southeast Asia. With early detection this cancer is treatable and curable in some cases.

This type of cancer is more common among heavy smokers and those who consume too much alcohol. Most oral cancers begin in the tongue and floor of the mouth.

Symptoms of tongue cancers

Tongue cancers usually grow significantly before showing symptoms of lack of movement of the tongue. They are clearly defined and spread easily.

They occur commonly over the sides of the tongue and are manifested as whitish patches called leukoplakia. These lesions are usually larger than 2 cm at presentation. The lesion may also appear grey to greyish-red with a rough and shaggy surface.

There may be pain at the site or in the ear.

Those that occur at the base of the tongue are usually silent until they have spread to the surrounding structures. Tongue cancers are commonly of the Squamous cell cancer type.

Tonsillar cancer symptoms

Tonsillar cancers are also commonly of the Squamous cell cancer type. These are commonly lymphomas.

These may present as a tumor over the neck. There are symptoms like sore throat, pain over the ear and feelings of something stuck in the throat. There may be bleeding.
