Colorectal cancer is the 2nd most common cancer in developed countries. A person's lifetime risk of ending up with this tumor is 1 in 20. Virtually all colon cancers arise from a pre-existing polyp, a phenomenon known as the adenoma-carcinoma sequence.
So here's the deal on colonoscopies. Much as you do not want to go through the icky prep, and much as you do not want someone touring your colon via a tube stuck up your backend, the fact is that colonoscopies are one of the most effective cancer screening tools we have. If a polyp (aka adenoma) is found during the procedure, it's removed on the spot.
Adenoma snagged, cancer averted. It's that simple. I've had mine, go have yours.
