You may want to start a new thread here specifically asking for advice regarding surgery with your situation. You might get more responses, that way.
I will link some archived threads below which may be helpful. The majority of them are from ostomates due to Crohn's or UC, but there are some other conditions which resulted in ostomies, as well.
You will hear time and time again that it is a personal choice, and that it so true. Just do your research, as you are doing, and it will help you make an informed decision. I kept a document on my desktop and cut and pasted all kinds of info that I wanted to remember including tips for pouching systems, ostomy products and preventing leaks--even months before my surgery.
I had "indefinite for dysplasia" in my colon, so I did opt for surgery. I didn't want to wait until it turned malignant, and then have to deal with radiation and chemo on top of surgery. It is a relief to me to not ever have to worry about CR cancer again, and no more colonoscopies was an added plus. I do understand how you feel though with your last 2 polyps being clean.
Since you don't have Crohn's, could you be a candidate for a J-pouch? I know there are several here who can help with that, as well.
Here are the links. The last one is from another board, and I hope that it is ok to link it here. I remember this man had to make the decision due to a malignancy in his colon. I think he is preparing for a J-pouch later down the road. There are others on this other board who have had colon cancer.
57 year old Grandma in the Buckeye State.
DX'd in 2006 with UC and in 2007 DX changed to Crohn's Colitis.
June 2010 had 10 inches of my colon removed due to a stricture.
Refused Remicade and Humira and opted for what I was certain the end result would be.
July 2011 had a proctocolectomy and permanent ileostomy without reservation.
Got my life back and stoma Lillie and I are doing great !!!
