I've seen a few posts on HN over the years on this exact topic. Always seems like the general consensus is people would like to get screened earlier. But their doctors won't order the test / insurance won't cover it until you're older.

Do we just lie then? Tell our doctors we have colon cancer that runs in our fam? That I saw blood in my stool last week?

Friend saw blood in her stool ONCE and her PCP ordered a colonoscopy immediately.

My grandfather actually had colon cancer and my parents keep nagging me to get screened. I tell literally all of my docs (PCP, therapist, med management doc, dentist, prob more I'm forgetting). Nobody has ever even acknowledged it. I guess I'll wait til I'm 50? 55? I don't even know.
