“We are being conned by all these so-called preventive tests and procedures.”
As someone diagnosed with colon cancer via a colonoscopy, which otherwise would have metastasized through my body to my lungs, liver, bones, etc., I recommend you learn how important a colonoscopy is.
Colon cancer is the pretty much the only cancer that can be “nipped in the bud”. Getting a colonoscopy every 5 years will almost completely prevent polyps in the colon from turning cancerous.
I recommend you research this a bit more before you run your mouth about something you clearly have no knowledge of.
Where do I begin? Every test has costs and risks and does not benefit everyone. Obviously, I do not know your personal situation, so I can’t comment on that. The books Worried Sick and another, Overdiagnosed, are quite interesting.
