[quote=marma]Did your mom have a biopsy where pathology actually confirmed leukoplakia? it could be other things like lichun planus, which can be treated to prevent recurring cancer. let me know. [/quote]

Actually, I do not recall now for sure. Initially, it was some suspicious looking patches in her mouth that Oral Pathologist/Dentist had noticed and said that they look like they can be pre-cancerous and should certainly be removed. Later on, another dentist/oral surgeon took a biopsy and that one came back with squamous cell carcinoma, which started it all. After the first surgery, doctor thought that my mother was cured, most likely forever, since the pathology report was good, the margins clear. But it recurred again and again later on...
