Chronic tonsillitis is mainly caused by mixed infections of bacteria or viruses, with the chronic inflammation of the tonsils often being caused by hemolytic streptococcus or Staphylococcus aureus. It is rare for chronic tonsillitis to become cancerous. The primary reason is due to the persistence of acute tonsillitis, which does not provide the conditions for cancerous changes. However, if individuals frequently consume spicy and stimulating food, or engage in smoking and drinking, this can cause local ulcers and lead to cancerous changes in the tonsils. Therefore, in daily life, if one notices cauliflower-like growths on the surface of the tonsils, special attention should be given, and a timely hospital check-up should be conducted to avoid the development of cancer.
