oncologist
(on-KOL-uh-jist)
A doctor who specializes in taking care of people with cancer. Some specialize in one type of cancer treatment. For example, a radiation oncologist treats cancer with radiation, and a medical oncologist treats cancer with medications. Some oncologists also specialize in one kind of cancer. For example, a breast cancer oncologist diagnoses and treats breast cancer.
