What is an Oncologist and How Can They Help You?

An oncologist specializes in cancer diagnosis and treatment. These physicians coordinate all aspects of cancer management including treatment planning, therapy administration, and ongoing supportive care.

Oncologists complete medical school, a three-year internal medicine residency, and a two- to three-year oncology fellowship. Medical oncologists may focus on specific malignancy types or pursue combined hematology-oncology training.

An Oncologist's practice responsibilities include:

  • Specializes in neoplastic processes throughout the body
  • Conducts cancer evaluations, orders diagnostic and staging studies, establishes cancer stages, formulates treatment strategies
  • Manages breast malignancies, pulmonary cancers, colorectal tumors, hematologic malignancies, lymphoproliferative disorders, and various solid neoplasms
  • Utilizes cytotoxic therapy, immunologic agents, targeted molecular therapy, hormonal treatment, and coordination with surgical and radiation specialists
  • Alternative names: cancer specialist, medical oncologist, MD, DO
