Solving a Colon Cancer Mystery

Colorectal cancer is the second leading cause of cancer death in the United States after lung cancer. The rates of lung cancer around the world vary by a factor of 10. If there was nothing we could do to prevent lung cancer—if it just happened at random—we’d assume that the rates everywhere would be about the same. But since there’s such a huge variation in rates, it seems like there’s probably some external cause. Indeed, we now know smoking is responsible for 90 percent of lung cancer cases. If we don’t want to die of the number-one cancer killer, we can throw 90 percent of our risk out the window just by not smoking.
There’s an even bigger variation around the world for colon cancer. It appears colon cancer doesn’t just happen—something makes it happen. If our lungs can get filled with carcinogens from smoke, maybe our colons are getting filled with carcinogens from food. Researchers from the University of Pittsburgh and the University of Limpopo sought to answer the question, “Why do African Americans get more colon cancer than native Africans?” Because colon cancer is extremely rare in native African populations, more than 50 times lower than rates of Americans, white or black.

My maternal grandmother died of colon cancer … painfully. My Mom had a near miss that required some surgical brilliance that gave her another 10 years of a pretty good life. I’ve recently had yet another colonoscopy that revealed some suspect tissue that has to come out. AND, I am following up aggressively.
Since it’s a “silent killer” that has no external symptoms until it’s too late, you have to be the Captain of your health are team.
Yes, it is — without a doubt — the most disgusting test to prep for. I do mine without anesthesia by personal preference. (I like to limit the things that can go wrong.) It’s no more painful than a case of constipation!
AND eat your veggies.
