The esophagus is an elongated muscular tube that connects the throat and the stomach. The prevalence of esophageal cancer has been rapidly increasing, with approximately 22,000 new cases diagnosed annually in the country. Despite a growing awareness of it, the condition can prove to be difficult to detect in its early stages. Thus, it is crucial to be vigilant about some common and alarming signs that indicate the presence of the condition. Warning signs of esophageal cancer Chest pain Patients with esophageal cancer might experience chest pain or discomfort, which is especially noticeable when swallowing. It might even feel like a tightness or burning sensation in the chest. Some patients might feel the pain radiating to the neck and back. Chronic cough Chronic cough or hoarseness that does not go away might also result from esophageal cancer because the condition affects the vocal cords and irritates the throat. Regurgitation Regurgitation is the involuntary return of food and fluids from the stomach to the esophagus. Persistent regurgitation may occur as a sign of esophageal cancer as it can cause blockage in the esophagus, preventing food from moving further down the stomach. Vomiting blood Hematemesis, or throwing up blood, is one of the alarming signs of esophageal cancer to look out for.
