A physician who specializes in the diagnosis and treatment of cancer.
A clinical oncologist is usually trained in one of the three primary disciplines of oncology:
Medical oncology – the treatment of cancer with medicine, including chemotherapy.
Surgical oncology – the surgical aspects of cancer including biopsy, staging, and surgical resection of malignancies)
Radiation oncology – the treatment of cancer with therapeutic radiation.
Once a cancer diagnosis is made, it is the oncologist's role to explain the cancer diagnosis and meaning of the disease stage to the patient; discuss various treatment options; recommend the best course of treatment; deliver optimal care; and improve quality of life both through curative therapy and palliative care with pain and symptom management.
