An oncologist is a medical doctor who specializes in the diagnosis and treatment of cancer. These specialists are trained to evaluate and manage various types of cancer, which can affect different organs and systems in the body. Oncologists use a range of techniques, including imaging tests,  tissue sampling, and laboratory analyses, to identify the type, stage, and extent of cancer in their patients. Treatment options may include surgery, chemotherapy, radiation therapy, targeted therapy, immunotherapy, or a combination of these approaches, depending on the individual's specific cancer type, stage, and overall health.
