Oral tumors are abnormal growths that can occur in the mouth, including the gums, tongue, and lips. They can be benign (non-cancerous) or malignant (cancerous) and may vary in size and appearance. Common types include squamous cell carcinoma and oral melanoma. Symptoms may include swelling, pain, difficulty swallowing, or changes in speech. Diagnosis typically involves a physical examination and may require a biopsy to determine the nature of the tumor. Treatment options depend on the type and stage of the tumor and may include surgery, radiation therapy, or chemotherapy. Regular dental check-ups can help in early detection of oral tumors.
