In the early stages of the development, oral cancer is often painless and its physical signs may not be obvious to the untrained eye. Oral cancer occurs where an abnormal group of cells (tumour) develop on the surface of the tongue, mouth, lips or gums. Less commonly, it can occur in the salivary glands, tonsils and the part of the throat that leads from your mouth to your windpipe (the pharynx).If diagnosed early, survival rates are high. Treatment can be a combination of radiotherapy, chemotherapy and surgery.
A cyst is a sac of tissue that has either fluid or soft material inside it. Cysts can form in a wide range of tissues including in the face and mouth. Some form next to or around teeth.
