What happens when there are to many polyps to remove during colonoscopy

I think this a very complex subject. They usually try and take representative samples because polyps come in all shapes, sizes and types. What they do about them depends on the types they have found and what they think is causing them. It doesn't follow that any are necessarily cancerous but it does lose more challenges to keep things that way. I would strongly suggest that after the biopsies you ask to see your specialist and ask him to explain slowly and carefully what they have found, what it means and what needs to be done. Doctors often tell you things rather quickly and at a time when you can't take it in. I ask my doctors to draw things to show me or use a model. I find this slows them down a bit and I can understand it much more easily. It's very important you follow everything and get the times right as to when you will need checks etc. The doctor can tell you whether more radical surgery, medicines or watchful waiting is what is needed. For your problem, you absolutely need to understand it from the experts because it is really too complicated for a website like this BUT the big thing is that it does not mean you must have cancer nor does it mean they can't do anything. I hope the biopsies turn out well for you and that they can devise a plan to keep this under control.

Sorry - "lose more challenges" in my reply is a typo and should read "mean more challenges"!

I live in the US, and a friend of mine had the same issue that occured with a colonoscopy.  He opted to have the part of the colon affected by a large number of polyps to be resected or surgically removed.  He has enough colon left to go on in life without any problems, and does not have a colostomy bag.  Every case is different though.
