The tonsils, mostly the palatine tonsils, are among the larger immune organs in the oropharynx, and their immune function is generally replaced by other lymphoid tissues after removal, with no effect on life expectancy. Tonsillectomy for early stage tonsil cancer can help prolong life. Tonsillectomy at early stage of tonsil cancer, supplemented with comprehensive treatment such as radiotherapy and chemotherapy after surgery, can be conducive to active treatment of the disease and enable patients to have a better survival period. As an immune organ, tonsil has its own physiological function. Especially in children, tonsils play an important role in protecting the body. Arbitrarily removing the tonsils will result in a short-term loss of local immune response and even immune surveillance disorders. Therefore, the indications must be strictly controlled. Tonsillectomy should be carefully selected with the advice of a specialist.
