Cancer of the oral mucosa
The tumor can develop on the mucous membrane of the cheeks, alveolar bone, soft and hard palate. The first sign is often the appearance on the mucous membrane of the growth of the epithelium in the form of a brush, wart; sometimes redness in a certain place where then erosion occurs - a mucosal defect, and then an ulcer. When probing the area around it, tissue compaction is determined. Comparatively early, cancer cells spread through nearby lymph nodes to surrounding tissues, including the tissue of the upper or lower jaw.
Leukoplakia deserves special attention - a mucosal lesion that can suddenly disappear and then reappear in the form of a whitish spot located on the cheek mucosa, more often along the closure of molars. Leukoplakia is a site of keratinization and desquamation of the epithelium of the mucous membrane and occurs due to its constant irritation: when the teeth close, trauma to the prosthesis, smoking. Experience suggests that the removal of these factors leads to the disappearance of the disease, the resumption - to its relapse. This is especially evident in smokers, when giving up a bad habit almost always relieves them of leukoplakia, and a return to tobacco - to its repetition.
