What are the symptoms of laryngeal cancer?
Hemoptysis: Because tumor stimulation can produce irritating dry cough, patients often have a sticky feeling of mucus. When clearing the throat, you will find blood in the sputum, which is generally manifested as persistent cough in the middle stage and blood in the late stage. It is also one of the symptoms of typical laryngeal cancer.
Blood in sputum: Because the tumor contains a large number of abnormal new blood vessels, patients often find blood in mucus or sputum after coughing. This symptom is mainly seen in patients with supraglottic and subglottic tumors and patients with advanced vocal cord tumors. Early vocal cord tumors generally do not produce bleeding.
Inner ear pain: when laryngeal cancer develops to a certain extent and produces ulcers and severe inflammation in the throat and stomach, it can cause reflex pain of nerves. Early vocal cord tumors generally do not produce reflex pain. Reflex pain mainly occurs in patients with advanced supraglottic tumors.
Refractory hoarseness: hoarseness is the earliest and most common signal of laryngeal cancer. Most cases of laryngeal cancer originate from vocal cords, that is, very small vocal cord tumors can also make the vocal cords vibrate abnormally, causing hoarseness. If the patient finds unexplained hoarseness, the symptoms last for more than three weeks and there are no signs of gradual improvement, he should go to the hospital in time and ask the otolaryngologist to do a careful laryngoscopy.
