Colonoscopies are common only in developed countries which pay for the expensive procedure (US)
- Risks vs. Benefits of Colonoscopies Dr/ Greger April 2018
"Other developed countries mostly use the stool tests, with only a few recommending colonoscopies or sigmoidoscopies. That may be because most physicians in the world don’t get paid based on how many procedures they do. As one U.S. gastroenterologist put it, “Colonoscopy is the goose that laid the golden egg.”
"A New York Times exposé concluded that the reason doctors rake in so much money is less about “top-notch patient care” and more about business plans maximizing revenue, lobbying, marketing, and turf battles"
Happened to check prices for procedures near me
MRI average prices of different cities ranged from $800 to $2,000
Colonscopies prices were all very close to $2,000 - a good indication pf price fixing
Observation April 2018 by Henry Lahore, founder of VitaminDWiki - The Pros and Cons of Colonoscopies Mercola Dec 2015
There are three ways to detect for colon cancer. The US way, colonoscopy, is 10X more likely to have complications, but gives the most kickback to the US doctor.
“it’s estimated that doctors make nearly a million more referrals every year than they would have if they there were not personally profiting.”
Nothing about vitamin D
The more vitamin D, the more prevention of Colorectal Cancer
