Stomach Cancer: About Stomach Cancer
This form of cancer begins when abnormal cells begin to grow in the stomach, the organ where food is digested. The stomach should not be confused with the abdomen, the lower part of the body between the chest and the pelvic area.
Cancers that occur in the abdomen affect the colon (large intestine), liver, pancreas, or small intestine. These cancers have different symptoms and different treatments.
After being chewed, food enters the esophagus, a tube in the throat, then passes through the esophageal sphincter, a ring-like muscle that opens into the stomach. After food is broken down by digestive juices, it passes out of the stomach, through the pyloric sphincter, another muscle, and enters the intestines.
