1. Stubborn hoarseness – Hoarseness is the earliest and most common sign of pharyngeal cancer. Most cases of pharyngeal cancer start from the vocal cords, even very small vocal cord tumors can cause abnormal vibration of the vocal cords and cause hoarseness. 2. Inner ear pain – When pharyngeal cancer develops to a certain extent and produces ulcers and severe inflammation in the throat, it can cause reflex pain of nerves. Early vocal cord tumors usually do not produce reflex pain, and reflex pain mainly appears in patients with middle and late stage supraglottic type tumors. The most common symptom is pain in the inner ear of the same side. Foreign body sensation in the throat – These are the early symptoms of supraglottic pharyngeal cancer, but tumors originating from the vocal cords may also produce foreign body sensation in the throat or painful swallowing once they develop to the middle and late stages. This type of symptom is often not obvious at the beginning of the disease, so it is easy for patients and doctors to overlook. 4. Blood in sputum – Because the tumor has a lot of abnormal new blood vessels, patients often find blood in mucus or sputum after coughing. This kind of symptom is mainly seen in patients with supraglottic and infraglottic tumors and patients with middle and advanced vocal cord tumors. Early vocal cord tumors usually do not produce bleeding phenomenon.
