Hello Dr, I am Praveen, Delhi. I was addicted to Man Masala with tulsi [tobacco] 5 years back I consume 5 to 10 pouches at different time intervals. I decided to quit & tried not to take even a single time, but coul not control & take 1 to twice minimum a day. Actually a week back I caught mouth ulcer during which it was difficult for me to take Gutkha. I taken medicines for mouth ulcer and with little more effort & will power, finally i have stopped taking [today is 4th Day]. Mouth ulcer is almost gone but the problem is the white & brown patches on my right cheek [where i hold masala previously] is troubling me with pain. I can t resist a little hot food in that area. Is it a cancer or a pre cancer. Can it be rectified by taking / applying medicine? Is there any home remedy to resolve!. I have putted salt directly on my mouth ulcer & also on White-Brown patches. Do i did it correct on applying saly on white brown patches? The pain is now lesser. Please guide.

Dear friend. Thanks for sharing your concernPlease do not get worried, lesion in your cheek could be due to oral ulcers, traumatic injury due to jagged teeth. Precancerous conditions, or oral cancer too.First it should be well examined through biopsy of the lesion. Visit your oral surgeon for clinical evaluation and biopsy. Do you have associated lymph node swelling? Local application of salt on the lesion is not recommended, But you can do warm saline rinses thrice daily especially after food.Also, it can be very well treated, whether ulcer or cancer, be stress-free. You can continue local application of colonel on the lesion for pain relief, also take vitamin B for 15 days. Visit your oral surgeon soon. Strictly quit your habit. Hope it helps. Thanks. Take care. Maintain very good oral hygiene.
