Esophageal cancer is a condition that develops due to the rapid and uncontrolled mutation of healthy cells in the esophagus. This mutation is triggered when the body mistakenly attacks its cells and tissue, impacting vital functions in the affected area. Cancer has no cure, and it is only possible to manage the spread and discomfort to a certain extent. Knowing these alarming signs of esophageal cancer and associated discomforts can help doctors decide the prompt course of action. Trouble with swallowing This cancer develops and affects the esophagus, so one will experience problems with swallowing. The healthy cells begin to mutate rapidly as cancer spreads and causes the passage to get constricted. Even the opening becomes too narrow, making it difficult to swallow food and beverages. Even after chewing properly, people might complain of pain while swallowing and morsels getting stuck midway due to constriction. And this symptom only becomes worse as the cancer progresses into the advanced stages. Developing a chronic cough The mutation of healthy cells in the esophagus also results in an excess buildup of mucus. This mucus formation is mainly triggered as an immune response by the body to keep the cells lubricated. Excess mucus further triggers a cough that persists and worsens with the spread of esophageal cancer.
