And the risks of the actual tests themselves, as well as the treatments that may be prescribed, are often higher than the purported condition being tested for. One of my pet peeves is colonoscopies. The complication rate and injuries for this testing is quite high, with awful consequences. But they are handed out like candy. But all it takes is one testimony that a person had a (ostensibly) budding colon cancer detected and is now a "cancer survivor", and people will line up to be reamed.
