Cancer of the esophagus is more common in males than females and in blacks than whites. It usually appears after age 50 and is associated with lower socioeconomic status. The most common symptoms are progressive dysphagia and weight loss. By the time symptoms appear, it is usually incurable since over 60% of the esophagus is usually infiltrated. Diagnosis involves endoscopy and biopsy to visualize and confirm tumors. Treatment options include surgery, radiation, chemotherapy, or a combination, but the prognosis is generally poor with less than 5% surviving more than 5 years.
