What is a colonoscopy?
- This examination is used to view the colon (large intestine) through a flexible tube (colonoscope).
- It helps the physician determine the nature of your health problem.
- It enables the physician to obtain tissue samples (biopsy) or remove polyps (small masses of tissue growing on the intestine lining).
- It is used to treat certain pathologies.
- It is also used to detect colon cancer.
