Mouth Cancer in US
Oral cancer accounts for about 3% of all cancers in the United States. About 30,000 cases are diagnosed every year, and about 8,000 people die from oral cancer every year. The incidence of oral cancer is rising.
About 95% of oral cancers occur in people over 40. The average age of diagnosis is about 60 years, although oral cancer is now more common in younger patients.
For decades, 6 men for every one woman have suffered from oral cancer (6:1). However, today this ratio is 2:1, most likely due to the increase in smoking and drinking among women.
Oral cancer is the fourth leading cause of cancer in African-American men.
