What causes esophageal cancer?Esophageal carcinoma arises in the mucosa. Subsequently, it tends to invade the submucosa and the muscular layer and, eventually, contiguous structures such as the tracheobronchial tree, the aorta, or the recurrent laryngeal nerve. The tumor
also tends to metastasize to the periesophageal lymph nodes and, eventually, to the liver, lungs, or both.
People who smoke cigarettes, chew tobacco, and drink alcohol are at a higher risk for this cancer. It is also thought that chronic and recurring irritation can increase the risk of esophageal cancer. These irritations include drinking very hot liquids, eating pickled foods, and being exposed to environmental toxins.
Esophageal cancer is rarely seen in people younger than 25 years old. The disease is more common in men than in women. It is seen more often in African Americans than in Caucasians. Overall, esophageal cancer is relatively uncommon in the United States. In some parts of Asia it is the second most common cancer, accounting for as much as 50% of all cancer deaths.
