There is about 1-10% chance every year of leukoplakia turning into cancer
after you have stopped tobacco, alcohol and betel nut
. It is more for speckled or thick nodular leukoplakia and leukoplakia on floor of mouth and RMT. I usually observe most of the oral leukoplakia which are thin and homogenous and remove those which are speckled and thick nodular or erythroplakia. 40-45% of the leukoplakia would remain static, 40-45% would regress and about 10-20% would turn into cancer if observed.
