Years ago I learned that this is the reason why they don't do colonoscopies without good reason in Finland. I asked from a doctor who is a friend why you have regular colonoscopies in the US but not in the Finland and he said "no evidence and colonoscopy has a small risk factor".

If you do medicine for profit and are allowed to advertise and market, doing more is always better.

as reported by the article, an impressive 50% reduction of cancer death for those who did colonoscopy.

I call that solid evidence which could potentially save millions of real lives.

Not included in the study is data about how many other screenings those people did

Not reported, how many people died from side effects of the procedure, such as blood poisoning/infection.

We care about all-cause mortality, not cancer mortality.

I haven't read the article - only the abstract, but it does report: "No perforations or screening-related deaths occurred within 30 days after colonoscopy." I guess something could have happened later than 30 days but we'd need the full article for that.
