What is oral cancer?

Oral cancer refers to malignant tumors occurring in the oral cavity or the maxillofacial region, mainly including various types such as tongue cancer, buccal cancer, gingival cancer, and cancer of the floor of the mouth. These cancers mostly originate from epithelial cells, with squamous cell carcinoma being the most common type. Early symptoms of oral cancer may include long-term non-healing oral ulcers, oral pain, abnormal bleeding, and abnormal sensations. However, these symptoms are not specific, so professional medical examinations are necessary for an accurate diagnosis. Treatment methods for oral cancer include surgery, radiotherapy, chemotherapy, and other approaches. The specific treatment plan should be formulated according to the patient's condition and the location of the lesion. Prevention of oral cancer primarily involves maintaining good oral hygiene and healthy lifestyle habits, as well as avoiding risk factors such as long-term smoking and alcohol consumption.
