Laryngeal cancer is a malignant tumor located in the larynx, which can be classified into supraglottic cancer, subglottic cancer, glottic cancer, and transglottic cancer. Any malignant tumor is not incurable; it mainly depends on how early it is detected. If laryngeal cancer is discovered early and treated correctly, promptly, and appropriately, the primary treatments include surgery, radiotherapy, and chemotherapy, among others. Under these conditions, the survival rate, cure rate, and life expectancy are quite high. However, if the laryngeal cancer has reached an advanced stage and has metastasized to other parts of the body or distant organs, the prognosis is poor, and the survival rate is relatively low.
