Bowel (Colorectal) Cancer Screening

Colonoscopy Screening Procedure and What To Expect
A colonoscopy is a procedure that allows the doctor to examine the inside of the large bowel using a thin flexible camera. It is commonly done for bowel cancer screening, change in bowel habit, bleeding, anaemia, abdominal symptoms, or follow-up of previous polyps.
Common patient experiences
For many patients, the bowel preparation is the most inconvenient part of the process. The colonoscopy itself is usually well tolerated because sedation is given to keep you comfortable.
After the procedure, you may feel drowsy for a few hours and experience temporary bloating or wind. Most people are able to eat and drink again once they are fully awake, and many feel reassured once the examination is complete and the findings have been explained.
Seek urgent medical advice if you develop severe or worsening abdominal pain, persistent vomiting, fever, heavy rectal bleeding, dizziness, or black stools after the procedure.
Most patients find that the colonoscopy itself is easier than they expected.
