《药物与人》杂志社:我今年54岁,身体还可以,没有什么大毛病,最近发现在口腔黏膜上有些浅白色、灰白色的白色斑状,尤其在两颊、舌尖、舌边分布较多。我去医院口腔科检查,说是口腔白斑,目前我还没有感到什么不适,就是有时食物摩擦到白斑处会感到疼痛。虽然这个病还没有给我带来太大痛苦,但我十分担心它会演变成口腔癌,请问口腔白斑癌变的可能性有多大,如何避免癌变吧?北京:王先生 Drugs and People magazine: I am 54 years old, the body is OK, no major problems, recently found in the oral mucosa some pale white, gray white spots, especially in cheeks, tongue, tongue distribution more.
