Is that true? I was under the impression that colonoscopies can reveal polyps which can be removed, thereby preventing progression to full-blown colon cancer.

You're right, but my point is probably still valid: a quick check suggests women over 40 should get a breast exam every year, while men and women should get a colonoscopy every ten years, starting at 40.
