What is Colonoscopy?

A colonoscopy investigates the large intestine together with the rectum and anus. It is done using a camera mounted at the end of a thin flexible tube. Samples of the large intestine can be taken for tests if there are any growths or unusual findings.

Should I go for Colonoscopy?

A colonoscopy is recommended if you have any of the following symptoms:

  • Pain in the lower abdomen / cramps
  • Lumps in the stomach
  • Blood in stools
  • Change in toilet habits (e.g. Constipation, watery or thin stools)
  • You are above 40 years of age with a family history of cancer/stomach ailments.


Why is a regular Colonoscopy important?

Colorectal cancer is the most common form of cancer in Singapore affecting both males and females. It is also one of the more preventable forms of cancer – most colorectal cancer develops from colon or rectal polyps. These small growths may increase in size and turn cancerous over time. Colon polyps usually have no symptoms.

A colonoscopy is the best form of prevention because it detects and removes the polyps. Prevention beats cure.
