A cancerous growth in the mouth, on the tongue, lips, or gums is known as oral cancer. The most prevalent type of mouth cancer is squamous cell carcinoma. Oral health care specialists detect many oral cancers through normal dental check-ups. It is crucial to pay attention to changes in the oral cavity for early detection, especially for persons who smoke cigarettes and consume alcohol on a daily basis. When oral and oropharyngeal cancer cells are in their early stages, they rarely cause symptoms. Many university hospitals, medical centres, and other organisations across the world are conducting research on oral and oropharyngeal cancers. Every year, researchers learn more about what causes these diseases, how to prevent them, and how to treat them more effectively. A lot of study is being done to learn more about the DNA mutations that cause cancer in the cells of the oral cavity and oropharynx.
