What I find really annoying is that doctors still won't sign off on a colonoscopy until you're 45. They will, but they do it in a way that apparently makes it not covered by insurance, despite the fact that a family member was diagnosed with colon cancer ~8 years ago. The current guidance says I shouldn't get one for another 13 years.
Everyone I have talked to about this has told me to just lie and say I have symptoms I don't have so I can get the "right" colonoscopy ordered that insurance will cover. It seems really stupid.
