Yes, my ruddy brother!!
Sorry, am going to be a bit blunt here ..... but I do know that anxiety is a horrible thing as I have it over other things.
My Dad died at age 62 with bowel cancer - no signs or symptoms whatsoever, (he was an medic so knew), and his mother had half her bowel removed in the 1950's. Therefore my brother and I have a familial chance of getting bowel cancer and I was advised by the geneticists that I had 5 yearly colonoscopies as should my brother ...... But despite having private health insurance from work, which in over 30 years he has never used, he will not even put a bit of pooh in a tube. Now I can understand a fear of doing it, but it could be far far worse if you didn't??
Colonoscopies aren't particularly pleasant, but neither is having major surgery and a Colostomy and having to deal with that on a daily basis, which I do for a reason totally unconnected to bowel cancer.
It's worth it if only to prevent it getting that bad that they do have to firstly do a colonoscopy, but then possibly have to cut half your bowel away and you may have to pooh in a bag?
Honestly - it's worth putting the pooh in a tube xx
