Summary: In the lab, using selected "standard lines" of cancer cells, it looked fairly plausible that iron encourages the growth of colorectal cancer cells. Eating "excessive" red meat seems very likely cause high iron concentrations in your lower intestines. Beyond that - YMMV.

So it's a junk headline? Also, telomerase activation is heavily correlated with longevity and less risk of disease.

Almost a strictly meat diet, but without all the confounding variables of sedentary office workers, industrial chemicals, and highly processed foods with tons of sugar.

  There's more to it than diet. Genetics also plays a large role. I'd be leery of generalizing dietary advice across ethnicities.

    ... and microbiota, too. Colorectal cancer is located at the end of a very densely "populated" tube. In all likelihood, Inuit microbiota is very far from Western one, at least as long as they don't adapt Western diet.

I wonder if tea, coffee, wine, phytate containing foods (beans, nuts) and calcium rich foods (dairy, etc) would counter the risk by blocking iron absorption.

  Just getting celiac disease would counter iron intake :-)

I have heard of there having been earlier studies that have linked iron intake with colon cancer growth, and I have personal reason to believe them. I have Lynch syndrome: a hereditary cell mutation which increases risk of colon cancer. Patients like me get a colonoscopy every eighteen months or so only to remove polyps. For a decade I had not had a single polyp to remove. Then in 2022, I got another cancer which gave me blood deficiency (low hemoglobin levels), and just to keep myself alive I took strong iron supplements for months. It did of course also stress my immune system. I got colon cancer in record time, which surprised also my doctors. It grew from no visible polyp (my last colonoscopy) to two inches in nine months, and in-between that I had an X-ray that also showed nothing (but which can't detect tumors small enough).
