Oncology is the branch of medicine that studies tumors (cancer). The oncologist often coordinates the multidisciplinary care of cancer patients, which may involve physiotherapy, counselling, clinical genetics, to name but a few. An oncologist often has to liaise with pathologists on the exact biological nature of the tumor that is being treated.
