Your stomach is where your food is digested.
Your food pipe is a tube that runs from your mouth to your stomach. It is sometimes called the oesophagus.
Cancer is an illness that starts inside your body. Tiny cells start to grow out of control and damage healthy parts of your body.
Cancer of the stomach and cancer of the food pipe are known as gastrointestinal cancers.
