Oral Cancer

* I have a white patch in my mouth?
* How can I prevent oral cancer?

I recently noticed a white patch in my mouth that won't seem to go away.
Should I be concerned?

Any mouth sore that persists for more than a week should be examined by your dentist. Leukoplakia is a thick, whitish-color patch that forms on the cheeks, gums or tongue and is caused by excess cell growth. It is common among tobacco users and can also result from irritations such as ill-filling dentures or a habit of chewing on one's cheek. The danger of leukoplakia is that it can progress to cancer. Your dentist may want to take a biopsy if the leukoplakia appears to be threatening.

How can I help prevent oral cancer?

Eliminate any risk factors such as tobacco and alcohol and regularly visit your dentist. Periodic dental exams allow early detection and appropriate treatment if cancer develops. If at any time you notice any changes in the appearance of your mouth or any of these signs and symptoms, contact your dentist at once:

" A persistent sore or irritation that does not heal
" Color changes such as the development of red and/or white lesions
" Pain, tenderness or numbness anywhere in the mouth or lips
" A lump, thickening, rough spot, crust or small eroded area
" Difficulty in chewing, swallowing, speaking or moving the jaw or tongue
" Change in bite
