The Oncologist was completely disinterested.The difference between uninterested and disinterested is as follows:
"Uninterested" refers to a lack of interest or concern; a person who is uninterested is bored or indifferent.
"Disinterested," in contrast, means impartial or unbiased; a disinterested person has no stake in the outcome.
I hence believe that you intended to say that your oncologist was "uninterested."

Actually, a better word might be dismissive. As a professional with a hospital to protect, if she could treat her own Illness, then the hospital was going to lose the business of providing her with a nutrition counselor, and other regular visits for care and treatment. This paid to the hospital and personnel through her insurance and/or Medicare.
