Donda West's doctor issues a statement to ET.

Dr. JAN ADAMS, the doctor who performed cosmetic surgery on KANYE WEST's mother, DONDA, before she died, has released the following statement to ET:

"I want to first express my deepest condolences to the West family at a very difficult time. As a medical doctor practicing in this field, I hold sacred the bond of confidentiality that exists between the patient and doctor. Out of respect of the West family, and the absence of verifiable information, any comment without having first discussing that information with the family would be unprofessional."
