Oral Cancer

Oral cancer Includes cancers of lips, tongue, buccal mucosa, floor of mouth, and pharynx. Tobacco usage is primary risk factor. Oral cancer is two times more prevalent in males. There are twice as many deaths in males as females. Older men, heavy users of alcohol and tobacco, and individuals exposed to sunlight are most likely to contract oral cancer. Among them, males 40 to 65 years of age have highest number of lip and tongue cancers
