Malaysia Statistic

Oral cancer is basically an abnormal growth found in the mouth region. This malignancy can be detected during routine mouth examination. Oral cancer commonly occurs at buccal mucosa (cheek), tongue, floor of the mouth and lip. This is fortunately one of the best cancers to detect early, because it presents in a part of your body that is so prominent and easily seen by yourself or, even if you fail to identify it in a mirror, your family and friends.

Throughout the world, oral cancer is the 6th most common cancers and annually there were 350,000 new cases reported worldwide. The survival rate of oral cancer is lower than that of cervical cancer, skin melanoma and breast cancer.

The incidence of oral cancer is predominant among the Indian ethnic group where mouth and tongue cancers were among the 10 most common cancer among both male and female. The incidence of oral cancer is highest in Indian females where the ASR was 10.2/100,000 female populations. Of those cases reported with staging, only 35.4% of the cases were diagnosed at stage I and II.

When detected early, oral cancer is almost always cured. But unfortunately, so many people still present with it at such a late stage. Oral cancer is more common in men than women because men tend to smoke more frequently.

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.
