Esophageal Cancer Prevention
Key Points for This Section
- Avoiding risk factors and increasing protective factors may help prevent cancer.
- The following risk factors may increase the risk of esophageal cancer:
- The following protective factors may decrease the risk of esophageal cancer:
- Cancer prevention clinical trials are used to study ways to prevent cancer.
- New ways to prevent esophageal cancer are being studied in clinical trials.
Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking, eating a healthy diet, and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer.
Adenocarcinoma of the esophagus is strongly linked to gastroesophageal reflux disease (GERD). GERD is a condition in which the contents of the stomach back into the lower part of the esophagus. GERD may irritate the esophagus and, over time, cause Barrett esophagus. Barrett esophagus is a condition that affects the cells lining the lower part of the esophagus. These cells change or are replaced with abnormal cells, which can lead to adenocarcinoma of the esophagus.
It is not known if surgery or other medical treatment to stop gastric reflux lowers the risk of adenocarcinoma of the esophagus. Clinical trials are being done to see if surgery or medical treatments can prevent Barrett esophagus.
Many studies have shown that the risk of esophageal cancer is lower in people who do not use tobacco and alcohol.
Some studies have shown that the use of nonsteroidal anti-inflammatory drugs (NSAIDs) may lower the risk of esophageal cancer. NSAIDS include aspirin and other drugs that reduce swelling and pain. Use of NSAIDs, however, increases the risk of heart attack, heart failure, stroke, bleeding in the stomach and intestines, and kidney damage.
Radiofrequency ablation is being studied in clinical trials for certain patients with Barrett esophagus. This procedure uses radio waves to heat and destroy abnormal cells, which may become cancer.
Cancer prevention clinical trials are used to study ways to lower the risk of certain types of cancer. Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer.
The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include eating fruits and vegetables, exercising, quitting smoking, or taking certain medicines, vitamins, minerals, or food supplements.
Clinical trials are taking place in many parts of the country. Information about clinical trials can be found in the Clinical Trials section of the NCI Web site. Check NCI's list of cancer clinical trials for esophageal cancer prevention trials that are now accepting patients.
