Oral cancer is one form of malignancy that is very easily detected through an oral examination.
It's appears as a growth or sore in the mouth that does not go away. Oral cancer, which includes cancers of the lips, tongue, cheeks, floor of the mouth, hard and soft palate, sinuses, and pharynx (throat), can be life threatening if not diagnosed and treated early.

According to the WHO (World Health Organization) data published in April 2011, oral cancer deaths in Malaysia reached 1587 or 1.55% of total deaths. The age adjusted death rate is 7.72 per 100,000 of population ranks Malaysia #14 in the world.
The Statistics
Types of Oral Cancer
What are the risk factors?
Your dentist will conduct an oral cancer screening exam. If an exam shows an abnormal area, a small sample of tissue may be removed. Removing tissue to look for cancer cells is called a biopsy. A pathologist then looks at the tissue under a microscope to check for cancer cells. A biopsy is the only sure way to know if the abnormal area is cancerous.
How Is Oral Cancer Diagnosed?
Self Diagnose

A white or red patch or a mixture of red & white patch on the gum, tongue, cheek or palate or lining of the mouth
An ulcer or sore in the mouth which do not heal after 3 weeks
A lump in any part of the mouth
Lumps in the neck of more than 3 weeks
Difficulty in swallowing,speaking and chewing
Difficulty in moving the jaw or tongue
Numbness of the tongue or other areas of the mouth
Chronic sore throat or hoarseness that persists more than six weeks
Swelling of the jaw that causes dentures to fit poorly or become uncomfortable
Unexplained bleeding, pain and weight loss

Squamous cell carcinoma
Salivary grand tumors
Risk factors for the development of oral cancer include:
Betel Quid Chewing
Smoking. Cigarettes, cigars, or pipes smoker are six times more likely than nonsmokers to develop oral cancers.
Alchohol.Oral cancers are about six times more common in drinkers than in nondrinkers.
Excessive sun exposure, especially at a young age
Family history of cancer.
Human Papillomavirus (HPV)
Surgery is often advocated when the cancer is deemed resectable. Chances for complete removal and fewer disturbances of function and appearance are dependent on severity of the cancer. Mouth cancer may spread to nearby lymph nodes in the neck, thus requiring removal during the same operation.
Radiation Therapy
Radiation therapy (also called radiotherapy). It affects cells only in the treated area. Radiation therapy is used alone for small tumors or for patients who cannot have surgery. It may be used before surgery to kill cancer cells and shrink the tumor. It also may be used after surgery to destroy cancer cells that may remain in the area.
Chemotherapy is the use of anticancer drugs to destroy the cancer cells. These drugs are usually administered by injection and the procedure requires the patient to stay in the ward for several days.
Avoid smoking or chewing tobacco and betel quid.
If you smoke, try to quit immediately. If you are a non-smoker, avoid passive smoke and strive for a smoke-free environment. Together with regular, high alcohol consumption, chance for a heavy smoker to develop oral cancer is even greater.

Limit alcohol consumption
Men should drink less than two standard alcohol drinks a day while women should not indulge in more than one.
Avoid excessive exposure to sunlight
Wear suitable clothing to protect skin against sun and apply sun lotion when staying outdoors.
Eat more green vegetables and fresh fruits – broccoli, spinach, beans, cabbage, apples, oranges, etc. These veges are rich in anti-oxidants. '
Maintain a healthy weight through balanced diet and exercise regularly.
