My Real Question Is Why There Is So Little Integrity

My real question is why there is so little integrity in the medical profession. My orthopedic oncologist told me I was at higher risk for fracture from Zometa. That the damage to my bones she saw in an x-ray was from Zometa. That my bones would be repairing themselves if only I wasn't on Zometa. When I brought this to the attention of the clinic director, that the orthopedic oncologist was telling me that my medical oncologist was prescribing a drug that was worsening my bone situation, suddenly the orthopedic oncologist denied making any of those statements. Isn't their supposed to be something called "medical ethics"?
