Esophagus causes. Pain or difficulty swallowing, food gets stuck. Esophageal spasms can do this transiently, and both scaringly and painfully!oropharynx/larynx can cause voice problems, breathing problems, and trouble swallowing, soemtimes pain goes to the ear. Smoking and alcohol are associated, and now that hpv is found, oral sex is postulated as a cause, another reason for vaccines against hpv for all.
Hoarseness,etc. Hoarseness and progressive dysphagia (difficulty swallowing), and weight loss are very prominent symptoms of esophageal cancer. Hoarseness is also seen in many throat cancers, and is due in both cases to laryngeal nerve palsy. Unilateral serous otitis media, nasal obstruction, or epistaxis (nosebleed) are seen in nasopharynx lesions.
