What are the symptoms of oral cancer?

Dental cancer, commonly referring to gingival cancer, is a type of malignant tumor in the oral and maxillofacial region. Its main symptoms are manifested in the following aspects: 1. Gingival ulceration: Patients with gingival cancer often experience damage and erosion in the gum area, eventually forming ulcers, which may be accompanied by secretion of foul-smelling fluid. 2. Gum pain and bleeding: Infiltration of cancer cells into the alveolar process and jawbone can damage bone tissue, causing pain and bleeding. 3. Tooth loosening: Due to damage to the periodontal ligament and alveolar bone caused by cancer cells, patients' teeth gradually become loose, and in severe cases, may even lead to tooth loss. 4. Difficulty opening the mouth: When lower gum cancer spreads to the cheek, floor of the mouth, or throat, patients may experience difficulty opening their mouths. 5. Gingival mass: Patients may notice a lump or papillary protrusion in the affected gum area. If any of the above suspected symptoms occur, prompt medical attention should be sought for professional examination and treatment.
