Tonsil cancer has a relatively high mortality rate. Tonsil cancer is a common malignant tumor of the pharynx. Its main clinical manifestations are irregular ulcerated surface of tonsils unilaterally or bilaterally with local bleeding and pus moss on the surface. Usually, patients show symptoms such as sore throat, discomfort in the throat, foreign body sensation in the throat, difficulty in swallowing, and in severe cases, weakness and difficulty in breathing. Tonsil cancer usually has lymph node metastasis, mostly squamous cancer, and usually submandibular lymph node metastasis, and metastatic sites can also be found in lung, bone, liver and other parts. Therefore, early detection and early treatment of tonsil cancer is of great significance to improve the survival rate. Therefore, when irregular ulcers are found on the surface of tonsils, it is necessary to go to hospital for examination and local pathology to confirm the diagnosis and timely treatment to maximize the chance of recovery.
