Thought I'd post again in case anyone comes across this post in the future. 

I had the Colonoscopy yesterday. The large polyp they found previously and one other large polyp were removed fully and will be sent for examination but the doctor said they are most probably benign which is a relief. I have quite a few smaller polyps which need removing so I have to have another colonoscopy in around 8 weeks to sort them. 

The experience was pretty unpleasant and uncomfortable if I'm honest. It took an hour for the procedure overall and I've been very bloated since but the doctor said it was almost certain that one of the polyps would have become cancerous before I reached the normal bowel cancer screening age so it was totally worth it! 

If you have blood in your stool, go to your GP and get it investigated regardless of your age would be my advice. I'm 30 so the chances of having bowel cancer were very low but removing polyps at an early stage will protect you from developing bowel cancer in future so having a slightly embarassing and uncomfortable procedure is 100% worth it.

Really glad you've got sorted. Did you have any other symptoms other than the blood? I'm expecting to be referred for a colonoscopy later today.

The blood was the main one that worried me but I also had pain in my stomach and changeable bowel habits from diarrhea to constipation. When I was constipated and did manage to go it was really thin so I knew there was something in there that was blocking the way.

I read your other post and it sounds really similar to my symptoms! I definitely know how you're feeling. A colonoscopy or a flexible sigmoidoscopy (which is the same thing as a colonoscopy but it just goes half way around your colon) will definitely give you a better idea of what's going on. I had about 2 weeks to wait for my flexible sigmoidoscopy when I was reffered by the GP and then when they found the polyp, it was another 2.5 weeks until the colonoscopy although a lot of times they can sort polyps just with the flexible sigmoidoscopy so you might not need both.
