Worldwide trends in esophageal cancer

1. Sex disparities

Approximately 70% of all esophageal cancers in the world occur in men, making it more common in men than in women.

2. What are the risk factors?

The risk factors for esophageal cancer include obesity, alcohol consumption, smoking, consumption of hot beverages, and diseases like gastroesophageal reflux disease, Barrett’s esophagus or damage to esophagus, and rare conditions like esophageal achalasia. Eating vegetables and increasing physical activity is known to decrease the risk.

The incidence of esophageal cancer is closely related to age; more than 85% of the patients in the United States are over 55 years of age. The risk of getting esophageal cancer increases with age.

3. Early detection is key to survival

The 5-year survival of esophageal cancer has increased in the United States from 5% in the 1970s to approximately 20% now, a number which includes early detection cases as well as advanced cancers. Esophageal cancer is often diagnosed after it has progressed, but early detection can greatly increase survival. Therefore, early detection of esophageal cancer is crucial.
