Hi there ,
I can understand your concerns,
The diagnosis of Leukoplakia
is made only when all other possible causes have been excluded by the doctors. The important thing to remember here is that it's not a cancer in itself but it can be transformed to cancer if left untreated.
The main causes includes smoking,alcohol consumption,ill fitted dentures or constant irritation.
There is one other condition which mimick Leukoplakia and should be excluded by a dermatologist
and it can be treated,and that is Oral Lichen Planus
. This is a chronic inflammatory condition of the skin an oral mucosa
I would also suggest that if your doctors are confused in diagnosing the condition then I think there is no harm in doing a skin biopsy
which can give us a confirmatory diagnosis and then they can proceed further.
I think the information will help you.
Thaan ka a lot and best of luck.
