Oral cancer is among the 3 most common cancers in the Indian subcontinent predominantly due to the unique habit of chewing tobacco as betel quid.
Tobacco use account for about 90% of these cancers. Another distinctive feature in this part of the world is the association of oral cancers with sub mucous fibrosis due to chewing areca nut (supari). This results into progressive difficulty in opening mouth (truisms). Infect oral cancer risk increases when tobacco is consumed with areca nut and alcohol. Furthermore, poor oral hygiene with resultant jagged edges of teeth causing persistent friction could result into a non healing ulcer of cancerous origin. Quitting tobacco significantly reduces the risk of cancer but may take up to a decade to equate a non tobacco consumer.
So does this mean all looks grim and gloomy when one falls prey to the dreaded disease? Fortunately not! Contrary to popular belief, oral cancers are curable when treated appropriately.
Another common belief about oral cancer is the futility of treatment in view of high risk of recurrence. The key to reduce chance of recurrence is early diagnosis, nailing the disease the first time over and maintaining a healthy lifestyle!
Take home message:
Oral cancer is one of the commonest; but preventable and fortunately curable!
