The site of origin of hypopharyngeal cancer is hypopharynx, also called laryngopharynx, which includes the pear-shaped fossa on both sides and the post-circumferential area.
Starting from tonsils and continuing to the entrance of esophagus, this length is called hypopharynx, also known as laryngopharynx, which includes the pyriform fossa on both sides and the post-circumferential area, and hypopharyngeal cancer is a malignant tumor originated from this area. The location of hypopharyngeal cancer is similar to larynx, which will produce laryngeal related symptoms. If the patient has cough, hoarseness, foreign body sensation in larynx, difficulty in swallowing and other clinical manifestations, hypopharyngeal cancer should be highly suspected. Generally speaking, hypopharyngeal cancer is detected at a late stage, with hidden symptoms and non-specific clinical manifestations.
If patients have difficulty in swallowing, foreign body sensation in the throat and other symptoms, they should consult doctor in time to make a clear diagnosis as early as possible, and the earlier the treatment, the higher the cure rate.
