An interesting thing about their colonoscopies: the business end of the probe is cleaned between patients. Now, I heard about this several years ago so might not be relevant any longer but, the disinfectant they were using was NOT doing a thorough job and people were exposed to the remains. It was dangerous.

In my estimation, I would rather take care of myself instead of subjecting myself to their "tests." IMHO, those te$t$ are more for drumming up business and scaring the people.
