The FDA approves the trials...and the doctor cannot deviate from the protocol. An example I'll give is the bone marrow biopsy. In the three times she had Lymphoma, she never had any positive bone marrow, and because of the protocol she had to get four different bone marrow biopsies...it got to be too much.
