Bowel Health Check with colonoscopy (referral form at the bottom of the page)

Bowel cancer develops through a well defined pathway. Bowel polyps (also called adenomas) can slowly grow over years in the lining (also called mucosa) of your bowels and become cancerous (also called carcinoma). Colonoscopy can remove these pre-cancerous growths and keep you cancer free. It is a very safe procedure where a flexible camera is inserted into your anus to examine your small and large bowel. Prior to your procedure you need to flush your bowels, by drinking bowel preparation and only having clear fluids the day prior to the procedure. Colonoscopy usually takes approximately 30 minutes and you will be given sedation medication to keep you comfortable and asleep.

Cancer Development

Symptoms

Many patients with bowel cancer or large polyps do not experience any symptoms. Depending on the size and the position of the cancer people can experience:

  • Blood in your stool or bleeding from the rectum.
  • Change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool
  • Abdominal pains, cramping or distention.
  • Fatigue
  • Weightloss
  • A feeling that your bowel doesn't empty completely
  • Anaemia

 

Bowel screening

In new Zealand people between the ages of 65 and 75 are offered screening where stool samples are analysed for traces of blood (FOBT). This program has been very successful and has detected many people who had cancer but no symptoms. Limitations of this test is that 40% of cancers do not bleed and therefore do not get detected by stool testing.

An absolutely awesome consultant, with an excellent and genuine concern for patient care. I consider myself extremely fortunately to have been referred under his professional care and his treatment, has genuinely improved my quality of life. By far the most supportive and expert gastroenterologist that I have ever had the pleasure of meeting. Thank you for your continued support.
