Definition
Cancer of the lip and oral cavity is a disease in which cancer cells are found in the tissues of the lip or mouth .
The oral cavity includes the front two-thirds of the tongue, the upper and lower gums ( gingiva ) , the lining of the inside of the cheeks and lips ( buccal mucosa) , the bottom ( floor ) of the mouth under the tongue , bone top of mouth ( hard palate ) , and the small area behind the wisdom teeth ( the retromolar trigone ) .
Description
Cancers of the head and neck are most commonly found in people who have more than 45 years .
Like most cancers , cancer of the lip and oral cavity is best treated when caught early .
Determining the stage of the cancer in the lip or oral cavity is important in order to plan the best course of treatment. There are a number of stages :
Causes
Lip cancer is more common in men than in women and is more likely to develop in people with fair skin that have been in the sun too long .
Cancer of the oral cavity is more common in people who chew or snuff smoke pipes .
Symptoms
It is important to consult a doctor if you have a lump on the lip , mouth or gums or a mouth sore that does not heal .
Another sign of cancer of the mouth or gums is when dentures no longer fit well . Often lip or oral cavity cancers are dentists when examined teeth.
Diagnosis
Diagnosis is made by clinical examination and a biopsy of the suspicious area .
Treatment
Early cancers (stages I and II ) of the lip and oral cavity are highly curable by surgery or radiotherapy, with the choice depending on the functional and cosmetic results .
Advanced cancers (stages III and IV ) are usually treated with a combination of surgery and radiotherapy. Some patients with small lesions not more affected lymph lymphatic 3/ 4 inches could receive surgery or radiation.
Patients with these stages often develop recurrences near the primary tumor or metastasis after treatment and should be considered for clinical trials of radiation modifiers or the use of combination chemotherapy in addition to surgery and / or radiation. Patients whose tumors grow blood vessels have a worse prognosis .
For recurrent cancer , treatment depends on the location and size of the recurrent tumor and the nature of the original treatment. If radiation therapy was used initially , surgery is preferred. If surgery was used at first , radiotherapy or a combination of both are used.
Since the results are poor treatment after using the "other" to repeat , consider clinical trials using chemotherapy or hyperthermia.
Prevention
To prevent oral cancer , do not use any kind of snuff .

Determining the stage of the cancer in the lip or oral cavity is important in order to plan the best course of treatment. There are a number of stages :
- Stage I. Cancer is no more than 2 centimeters and has not spread to lymph nodes in the area
- Stage II. The cancer is larger than 2 centimeters but less than 4 centimeters and has not spread to lymph nodes in the area
- Stage III. Any of the following may be true - the cancer is larger than 4 centimeters , the cancer is any size but has spread to a single lymph node on the same side of the neck as the cancer .
- Stage IV. Any of the following may be true - the cancer has spread to tissues around the lip or oral cavity , lymph nodes in the area may or may not contain cancer , the cancer is any size and has spread to more than one node lymph on the same side of the neck as the cancer , to lymph nodes on one or both sides of the neck , or to any lymph node that measures more than 6 centimeters.
