I had been diagnosed with leukoplakia,the doctor said there is no need for biopsy and gave me antioxidants and kenacort gel . Recently I have observed that whenever I gently rub my mucosa with my fingers a white coloured stuff (skin) peels out,there is no pain ,I want to know that is this something serious? And I also have a small movable lump in my cheek just below my left eye ,it's not visible directly but I can hold it ,it's hard and movable ,I am really afraid please guide me!!
