Oncology Career and Certification Overview

Oncology is the medical specialty dealing with the diagnosis and treatment of tumors and cancer. Medical oncology teams include radiation therapists and physicians.

Radiation Therapists Career Information

Radiation therapists use imaging machines to locate tumors. They also operate linear accelerators, which beam X-rays targeted at a patient's cancer cells. Additional responsibilities include helping physicians develop treatment plans, monitoring patients during treatment and maintaining records.

Certification Information

The American Registry of Radiologic Technologists (ARRT) offers certification for individuals working in radiation therapy. Individuals must complete a radiation therapy program accredited by the Joint Review Committee on Education in Radiologic Technology. During the education program, radiation therapists must demonstrate clinical competency for a program director.

Besides meeting education requirements, certification candidates must meet AART ethical standards and pass an exam. Radiation therapists must register with the ARRT annually and complete 24 continuing education credits biennially to maintain their certification.

Oncology Physician Career Information

Oncology physicians, or oncologists, specialize in the diagnosis and treatment of patients with cancer. Specialties and subspecialties are based either on the type of cancer or the method of treatment. For example, internal medicine physicians specializing in medical oncology treat or manage cancer in the vascular system, heart, lungs and kidneys.

Other specialties include gynecologic oncologists, who specialize in treating the female reproductive system, and pediatric hematology-oncology physicians, who focus on children with cancer in the spleen, lymph nodes and bone marrow. Radiation oncologists prescribe radiation therapy and surgical oncologists operate to physically remove cancer from a patient.

In general, oncology physicians first complete up to eight years of undergraduate and medical school education to earn either a Doctor of Medicine (M.D.) or Doctor of Osteopathic Medicine (D.O.) degree. They then must pass the United States Medical Licensing Examination or the Comprehensive Osteopathic Medical Licensing Exam before pursuing training in an oncology specialty or subspecialty. Certification varies by specialty area.
