2tuff...Can we prevent or dissolve colon polyps?

Just wondered what your feelings were on this. If we only know if we have colon
polyps by taking a colonoscopy, and we don't want to do that, is there a protocol
to dissolve possible polyps that may be there?

Also, if we were told at age 10 (after a colonoscopy) that the lining of our colon indicated we would have colon cancer by age 50, what could we do to prevent that?

What are your thoughts on colonoscopies, and what is a good alternative to assuring
ourselves we don't have colon cancer or polyps?

Just curious what your thoughts were on these issues! Thanks Lee
