Hematology and Oncology

An Oncologist 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.

Oncologists diagnose cancer through methods such as biopsy, endoscopy, X-ray, blood tests, ultrasound, and different forms of nuclear medicine. They treat cancer through surgery, chemotherapy, radiotherapy, hormone therapy, or antibody treatments.

If it is determined that a cancer cannot successfully be treated, oncologists then focus on providing palliative care, the use of pain medication to make a dying person more comfortable.
