Dr. Fred Klein MD whom is a gastroenterologist in Tucson, Arizona is a dangerous Physician, and a threat to public safety. My cousin nearly died a few years back after he perforated her bowel during a routine colonoscopy. Ultimately she survived due to a different doctor intervening and saving her life. The worst part is that it was covered up as best as posssible, and since he is well connected, no higher authority even discussed this case as well as others he was associated with bad outcomes

My advice is seek second opinions all the time to avoid this travesty.
