Oral cancer is a type of cancer that occurs in the mouth or throat and can affect the lips, tongue, cheeks, gums, palate, or throat. It often starts as a small, unnoticed white or red patch or a non-healing sore. Risk factors for developing oral cancer include smoking, excessive alcohol consumption, and human papillomavirus (HPV) infection. Research in the field of oral cancer focuses on understanding the causes of the disease, developing effective prevention and early detection strategies, and improving treatment options. This includes studying the genetic and molecular mechanisms of oral cancer development, identifying biomarkers for early detection, and evaluating new therapeutic approaches such as targeted therapies and immunotherapy. Overall, research in oral cancer aims to improve outcomes for patients by advancing our understanding of the disease and developing more personalized and effective treatment strategies.
