An oncology specialist is a physician who focuses on the diagnosis and treatment of different cancers. This physician has extensive knowledge of the different signs and symptoms of cancer, as well as the various methods of treatment.
Oncology specialists diagnose cancer through methods such as biopsy, endoscopy, X-ray, blood tests, ultrasound, and different forms of nuclear medicine.
Oncology doctors treat cancer through surgery, chemotherapy, radiotherapy, hormone therapy, or antibody treatments.
If it is determined that a cancer cannot successfully be treated, oncology specialists then focus on providing palliative care - the use of pain medication to make a dying person more comfortable.
