An Oncologist is a physician whose duty is to diagnose and treat cancer. These specialized doctors explain the process of the disease and what stage it is in at the time of diagnosis to the patient, discuss treatment options and recommend the best treatment plan. Oncologists can specialize in medical, surgical, radiation or pediatric. Every oncologist must choose to specialize in one of those fields.
Every oncologist works with cancer patients, but each one has a different task, different tools and a different approach to treatment. Because cancer is such a difficult disease to fight, each of these jobs plays an important part in cancer therapy, and often several different types of treatment are combined for a single patient.
