Oncology is a specialty branch of medicine pertaining to the diagnosis and treatment of cancer. Oncologists may practice sub-specialties, serving as a primary medical doctor, oncologic surgeon, or an oncologic radiologist. Patients often have more than one oncologist spanning across multiple sub-specialties. Each oncologist works together for the benefit of the patient and to achieve the most favorable outcomes possible.
Cancer specialists help patients through each phase of treatment. They are responsible for conducting biopsies and other tests that help grade the stage, aggression, and progression/regression of cancer cells in the body. Oncologists use highly advanced technology and procedures to both diagnose and treat cancer. They also develop, carry-out, and occasionally modify treatment plans that may include surgery, radiation, chemotherapy, immunotherapy, targeted therapies, photodynamic therapy, stem cell transplants, or even hyperthermia heat treatments.
