My younger brother wax diagnosed with colon cancer at 29, and died from secondary cancer in his liver 6 years later. (in 2013)
After his diagnosis I had a colonoscopy, just to rule out any family connection.
I can honestly say the previous day taking the picolax stuff was worse than the main event.
However I did make a point of telling the anaesthetist that I was a total wimp and to go large with the sedatives.. I don’t remember much after that.
I’d gladly have a colonoscopy anytime again if it caught bowel/colon cancer in the early stages.
My 9 year old daughter also had a colonoscopy last year to investigate/rule out coeliac disease.. so if a 9 year old girl can handle it….
