6. Upper Airway Obstruction
Another esophageal cancer symptom is upper airway obstruction. This can be characterized by having a wheezing sound, especially when inhaling and exhaling air, which is caused by the rough air passage in the larynx just right above the respiratory tree. As tumors in esophageal cancer tend to grow bigger and even multiply and scatter, the air tract may be affected as it compresses the passages to the upper respiratory tract.
There are other illnesses that can cause a similar symptom of havingan upper airway obstruction such as asthma, chronic obstructive pulmonary disease, allergies, and more. Consult your physician when you experience stridor for proper diagnosis.
