Avoiding risk factors and increasing protective factors may help prevent cancer.
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.
Childhood astrocytoma is a disease in which benign (noncancer) or malignant (cancer) cells form in the tissues of the brain.
Astrocytomas are tumors that start in star-shaped brain cells called astrocytes. An astrocyte is a type of glial cell. Glial cells hold nerve cells in place, bring food and oxygen to them, and help protect them from disease, such as infection. Gliomas are tumors that form from glial cells. An astrocytoma is a type of glioma.
Astrocytoma is the most common type of glioma...
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.
