General Information About Langerhans Cell Histiocytosis (LCH)

Langerhans cell histiocytosis is a type of cancer that can damage tissue or cause lesions to form in one or more places in the body. Langerhans cell histiocytosis (LCH) is a rare cancer that begins in LCH cells (a type of dendritic cell which fights infection). Sometimes there are mutations (changes) in LCH cells as they form. These include mutations of the BRAFgene. These changes may make the LCH cells grow and multiply quickly. This causes LCH cells to build up in certain parts of the body,...

The following risk factors may increase the risk of esophageal cancer:

Tobacco and alcohol use

Squamous cell carcinoma of the esophagus is strongly linked with all types of tobacco and alcohol use. Stopping smoking can help lower the risk of this type of cancer.

Gastric reflux and Barrett esophagus

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.

The following protective factors may decrease the risk of esophageal cancer:

Avoiding tobacco and alcohol use

Many studies have shown that the risk of esophageal cancer is lower in people who do not use tobacco and alcohol.


A diet high in green and yellow fruits and vegetables and cruciferous vegetables (such as cabbage, broccoli, and cauliflower) may lower the risk of squamous cell carcinoma of the esophagus.

Nonsteroidal anti-inflammatory drugs

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.
