BASED ON YOUR QUERY, IT SUGEGSTS TO ME THAT YOU ARE HAVING A LEUKOPLAKIC PATCH (NOT THE ORAL CANCER
Smokeless tobacoo is one of the main reason for leukoplakic patches on buccal mucosa. Leukoplakia patch
are generally white, ELEVATED patches, having LEATHERY consistency (feels like hard skin), having either smooth/ corrugated (Rippled) surfaces. It is geenrally WHITE, but it may take up the color from leached out products of tobaccoo chewing which may discolr the white patch
NOW, first of all, even if it is leukoplakia, the chances of it being turning into cancer depends on histopathological findings after a BIOPSY of that area by an oral surgeon (more the redness
, ulcerations, proliferative growths, more are the chances).
BUT MOST IMPORTANTLY ONLY A FRACTION (LESSER THAN 4%), OF LEUKOPLAKIC PATCH TURNS INTO CANCER, THESE LESION MOST OF THE TIMES ARE REVERSIBLE (TURNS BACK TO NORMAL), IF ONE ABSOLUTELY QUITS TOBACCOO IN A MATTER OF MONTHS.
Still if you doubts about any symptoms, better, geT a simple, painles brush biopsy test or an incisional biopsy test done by an oral surgeon.
