Tonsil Cancer: When a Hidden Growth Develops in the Throat Tonsil cancer can develop in the back of the throat, where early changes may be difficult to notice. It occurs when abnormal cells grow uncontrollably in the tonsil tissue, forming a tumor that may gradually affect surrounding structures. Some cases are associated with human papillomavirus (HPV) infection. Warning signs may include a persistent sore throat, difficulty swallowing, one enlarged tonsil, ear pain, or a lump in the neck. Recognizing persistent throat symptoms and seeking timely medical evaluation can support earlier diagnosis and more informed treatment decisions. Learn more. Understand your cancer.
