Subglottic laryngeal cancer is a malignant tumor of the larynx located in the subglottic area, which can have symptoms such as hoarseness.
Subglottic laryngeal cancer is a malignant tumor located in the subglottic area, i.e. the lower edge of the vocal folds to the lower edge of the cricoid cartilage. Early symptoms of subglottic laryngeal cancer are often not obvious, and the main symptoms include hoarseness, pain, throat discomfort, foreign body sensation and dyspnea, etc. Subglottic laryngeal cancer can go down to the lower part of the vocal folds. Subglottic laryngeal cancer can invade the trachea downward, invade the muscle layer of the anterior neck forward, invade the thyroid gland on both sides, etc. It can also metastasize to the thyroid gland through lymphatic transfer. It can also metastasize to laryngeal cavity and paratracheal lymph nodes through lymph.
The disease can be diagnosed by palpation, laryngoscopy, and biopsy of diseased tissue. Its treatment mainly includes comprehensive treatment such as surgery, radiotherapy and chemotherapy. Compared with vocal cord cancer and supraglottic cancer, its prognosis is poor.
If there is any discomfort, it is recommended to consult a doctor in time for diagnosis and treatment.
