Tonsil cancer is a type of oropharyngeal cancer that affects the tonsils, the two oval-shaped pads at the back of your throat. While it's less common than other types of cancer, its symptoms can often be mistaken for less severe illnesses, making it crucial to understand what to watch for. The American Oncology Institute offers insights into this condition, emphasizing the importance of early detection. The three primary risk factors for tonsil cancer are: smoking, heavy alcohol use, and human papillomavirus (HPV) infection.
