Endoscopy

Endoscopy is a detection method that allows a doctor to look into the body through a long and flexible tube called an endoscope. An endoscope contains fibers that transmit light. An endoscope is most often inserted through the mouth or rectum. During the examination, the doctor can take a biopsy, or tissue sample, from the suspected tumour. The sample is looked under a microscope to see if the cells are normal or cancerous.
