An endoscopy is a test that looks inside the body using an instrument called an endoscope.
An endoscope is a thin, flexible tube. The tube has a light and a camera at the end. It is passed into the body to help doctors see inside.
Endoscopy tests can be used to help diagnose cancer. They can help doctors to find out more about your symptoms. They can also be used to give some types of treatment from inside the body.
An endoscopy may also be used to remove a small sample of tissue from inside the body. This is called a biopsy.
