I had lichen planus which is not dissimilar to leukoplakia before I got the cancer. No one seemed to know much about it so my GP sent me to a dermatologist who tested me for allergies. I showed a sensitivity to mercury and amalgam fillings so had all those replaced to no avail. The patch of lichen planus grew worse over the years. It took many years to turn into cancer if that is any comfort and my GP's and dermatologist's lack of action were both determined by a senior guy, an oral surgeon who said categorically that it was just lichen planus and there was nothing they could do. In hindsight I should have asked to see someone else ... like an ENT. You are already at that stage but if you are worried you could seek out someone who specialises in leukoplakias etc. I don't think a naturopath's treatments can do much to affect cellular changes within the tissues of the mouth. It would be better to see someone who has researched these lesions and written papers on them. I think you are wise to be vigilant but don't fret and spoil your enjoyment of life. just make sure you have taken all the necessary steps. Best wishes!
