Vocal cord swelling and coughing up blood may be related to transglottic laryngeal cancer, laryngeal hemangioma and other diseases.
1. Transglottic laryngeal cancer: It is common in squamous cell carcinoma of larynx whose lesion involves supraglottic and glottic area, and it is mostly related to smoking, drinking alcohol, air pollution and viral infection. When the cancer invades blood vessels, it can show the symptom of coughing up blood.
2. Laryngeal hemangioma: Symptoms of laryngeal hemangioma are hoarseness, cough, hemoptysis occasionally, and there are also asymptomatic people. Most of them are located in the vocal cords, laryngeal chamber, pseudo vocal cords and aryepiglottic folds. Tumor protrudes from the mucosal surface, often red or purple, surface blood vessel rupture, may show symptoms of coughing up blood.
When you find the symptoms of coughing up blood in the vocal folds, you need to follow the doctor’s instructions and systematic examination to make a clear diagnosis, and then standardize the treatment.
