Significance of esophageal cancer
Esophageal cancer prevention

Esophageal cancer is cancer of the esophagus, the muscular tube through which food passes from the throat to the stomach. Most esophageal cancers are either adenocarcinoma or squamous cell carcinoma. Both types of cancer are found in the tissue that lines the inside of the esophagus. Squamous cell cancers occur in the upper part of the esophagus near the throat and adenocarcinomas occur in the lower part of the esophagus near the stomach.

The number of new cases of squamous cell cancers of the esophagus is declining. African American males are more likely to develop squamous cell carcinoma of the esophagus than are white males. The risk of this type of cancer increases with age for all racial/ethnic groups.

The number of new cases of esophageal adenocarcinomas has risen over the past 2 decades. It has become more prevalent than squamous cell cancer of the esophagus in the United States and Western Europe.

The following risk factors and preventive factors may affect whether a person develops esophageal cancer:

Tobacco and Alcohol

Squamous cell cancer of the esophagus is strongly associated with tobacco and alcohol use. Studies have shown that avoiding tobacco and alcohol decreases the risk of developing esophageal cancer.

Diet

A diet with plenty of green and yellow fruits and vegetables and cruciferous vegetables (such as cabbage, broccoli, and cauliflower) may lower the risk of developing squamous cell cancer of the esophagus.

Nonsteroidal Anti-Inflammatory Drugs

Some studies have shown that the use of nonsteroidal anti-Inflammatory drugs or NSAIDs (such as aspirin and other drugs that reduce fever, swelling, pain, and redness) is associated with a reduced risk of developing both squamous cell cancer and adenocarcinoma of the esophagus. Use of NSAIDs, however, increases the risk of heart attack, heart failure, stroke, bleeding in the stomach and intestines, and kidney damage.

Helicobacter Pylori Infection and Gastric Atrophy

Infection with the Helicobacter pylori bacteria causes inflammation and ulcers in the stomach lining, which may lead to a condition called gastric atrophy (cells that line the stomach are destroyed). This condition may increase the risk of developing squamous cell cancer of the esophagus.

Gastric Reflux and Barrett Esophagus

Gastric reflux (the backing up of stomach contents into the lower section of the esophagus) may irritate the esophagus and, over time, cause Barrett esophagus. Barrett esophagus is a condition in which the cells lining the lower part of the esophagus have changed or been replaced with abnormal cells that could lead to adenocarcinoma of the esophagus. It is not known if surgery or other medical treatment to stop gastric reflux will reduce the risk of developing adenocarcinoma of the esophagus.
