One of the key oncologist job description criteria is that an oncologist must supervise an oncology medical unit and ensure that the patients that are admitted get the best possible medical care. One important aspect of an oncologist's job is that he must work with the Head of Department of general medicine so as to plan and ensure the best possible options for treatment of cases. Oncologists first diagnose cancer using biopsy, endoscopy, X-ray, CT scanning, MRI scanning, PET scanning, ultrasound or other radiological methods. Nuclear medicine, as well as blood tests and tumour markers, can also be used for diagnosis. Once diagnosed, oncologists discuss the disease, including stage, with patients. Staging, in turn, dictates the type of cancer treatment. An oncologist (cancer specialist) must have excellent inter and intra-personal communication skills so that he can manage his team of health care providers, while also managing his patients and handling their doubts in a professional manner.
