Oral cancer is a serious disease that affects the lips, tongue, cheeks, gums, and throat. It often begins as persistent sores, lumps, or red and white patches in the mouth. Risk factors include tobacco use, excessive alcohol consumption, HPV infection, and prolonged sun exposure. Early detection through regular dental checkups and screenings improves treatment success. Diagnosis involves biopsies and imaging like CT scans or MRIs. Treatment options include surgery, radiation therapy, and chemotherapy. Preventive measures such as avoiding tobacco, maintaining oral hygiene, and a healthy diet reduce risks. Early intervention is crucial for improving survival rates and overall health.
