Throat cysts caused by benign diseases are usually not cancerous. However, throat cysts secondary to diseases such as laryngeal tumors have a higher chance of becoming cancerous. Throat cysts usually include tonsillar cysts, epiglottis cysts, submucosal cysts of the vocal cords and laryngeal ventricular cysts, which may cause throat discomfort or foreign body sensation and are usually not cancerous. However, some laryngeal cysts may be secondary to malignant lesions such as laryngeal tumors, resulting in cyst-like structures, which have a higher chance of becoming cancerous and may form laryngeal cancer. It is recommended to visit the ENT department of a regular hospital and improve relevant examinations under the guidance of doctors to clarify whether cancer will occur. In addition, patients should pay attention to the neatness and cleanliness of the surrounding environment and keep the air circulation, and it is recommended to quit smoking and drinking and eat less spicy and stimulating food to avoid affecting the condition.
