Symptom 2: The early symptoms of laryngeal cancer are not obvious, and they are often easily confused with the symptoms of laryngitis. However, there are some symptoms in the early stage, such as foreign body sensation, sore throat, dysphagia and hoarseness, which have many similarities with pharyngitis, so they are often mistaken for "getting angry" or pharyngitis.
Symptom 3: hoarseness. Glottic carcinoma is the most common type of laryngeal carcinoma in Guangdong. Because the tumor grows on the vocal cords, it is easy to cause hoarseness in the early stage. For patients over 40 years old with hoarseness exceeding 1 month, they can go to the hospital as soon as possible to check for laryngeal cancer.
Symptom 4: foreign body sensation in pharynx, obstruction and dysphagia. For people over 50 years old who have the above symptoms repeatedly 1 month, they need to be alert to the risk of laryngeal cancer. Bloodshot and phlegm. Seeing a small amount of bloodshot in sputum, especially the first sputum in the morning, we should be highly alert to the risk of cancer in the throat.
Symptom 5: Sore throat. Foreign body sensation or swallowing pain in the throat: these symptoms are the early symptoms of supraglottic pharyngeal cancer, but once the tumor originating from vocal cords develops to the middle and late stage, it will also produce foreign body sensation or swallowing pain in the throat.
Symptom 6: Dysphagia and dyspnea, which are relatively late symptoms. However, doctors say that about 60-70% of patients, especially patients with non-glottic laryngeal cancer, only see a doctor at this time, and often find that the cancer is in the advanced stage, which greatly reduces the value and curative effect of treatment.
