White patches on the throat, tongue, or inside the mouth are called leukoplakia. They cannot be scraped off by rubbing or by toothbrush and appear as slightly raised gray to white patches.
Leukoplakia patches have a rough surface with an underlying raw area that may bleed on being scratched. Although these patches do not necessarily mean cancer, they may develop into cancer if left untreated.
You must contact your doctor for a definitive diagnosis of the white patches.
