Colon Cancer Screening​


What is a colonoscopy?

Colonoscopy involves the gentle insertion of a flexible fiberoptic camera scope through the anus and into the rectum and colon. The surface of the colon is then viewed on an HD screen in real-time. If the colon is properly cleaned, the scope can detect even small polyps and other surface abnormalities. It is the gold standard in early colon cancer detection. More accurate than a CT scan or MRI.

Is it painful or dangerous?

Colonoscopy is done under monitored sedation so patients often sleep comfortably through the entire procedure and cannot remember even going through it. In trained hands, it is a very safe and quick procedure with complication rates of less than 1%.

When should I have my first colonoscopy?

Ministry of Health recommends an initial screening at the age of 50 for low-risk and asymptomatic patients. For patients with a family history of colorectal cancer, screening should begin earlier. The age of the affected family member minus 10 years is a useful guideline. In the United States, health authorities have lowered the age of initial screen to 45 years old in recognition of younger colorectal patients.

How to prepare for a colonoscopy?

Initial consultation with the specialist is necessary. During the consultation, the doctor will assess if the patient is fit to undergo a colonoscopy. Certain medications like blood thinners and diabetic medication will need to be stopped. Possible complications will also need to be informed to the patient and informed consent signed.

Can I claim Medisave or insurance?

Yes. Colonoscopy is insurance claimable. This will be discussed during financial counselling at the initial consultation.

Extended Panel means you can see doctors who are not on your insurance panel. Ask your doctor.
