An endoscope is a medical tool that is used by doctors to see inside your body without making big cuts. It is a long, thin tube with a camera and a light at the end. The doctor can look at pictures from the camera on a screen and use the endoscope to do small procedures inside your body, like taking a sample or removing something. It is often used to look inside the stomach, intestines, and lungs.
