radiation oncologist at moffitt


If you’re wondering what the difference is between a radiation oncologist and a radiologist, you’re not alone. Along with having similar-sounding names, both are highly specialized doctors and both are involved in developing a patient’s cancer treatment plan. So, how exactly do they differ? Let us help you understand their unique roles in diagnosing and treating a patient with cancer.

What does a radiation oncologist do?

First, the word “oncologist” is used to describe a physician that specializes in treating cancer. A radiation oncologist works alongside surgical oncologists and medical oncologists to determine if and how radiation oncology fits into a patient’s treatment plan. The radiation oncologist determines the delivery method and dosage of radiation therapy to be provided to a patient.

What does a radiologist do?

A radiologist specializes in using medical imaging techniques to diagnose and treat different conditions, including cancer. In fact, almost all cancer cases require a radiologist to perform an imaging procedure for the initial diagnosis, whether it be a computer tomography (CT) scan, X-ray, ultrasound, mammogram, magnetic resonance imaging (MRI) scan or another form of medical imaging. When diagnosing a suspected cancer, a radiologist is responsible for:

  • Determining the most appropriate imaging technique to use
  • Examining medical images and interpreting the results to provide a diagnosis
  • Working with other physicians to help recommend a treatment plan

In addition to interpreting diagnostic imaging, an interventional radiologist specializes in performing minimally invasive techniques using medical imaging to guide the treatment.
