Interventional radiology, which is also referred to as vascular and interventional radiology, uses minimally invasive radiology both to treat and diagnose diseases, disorders, and other problems a wide variety of patients may face. Generally, doctors in this subspecialty want to make the procedures they perform as minimally invasive as possible, as this reduces the possibility of other problems and complications. Physicians usually learn about interventional radiology while they are completing their residencies.

Radiation oncology is the field of medicine that aims to treat cancer with radiation therapy. The doctors who treat cancer in this way have an in-depth understanding of the unique problems patients face when they undergo radiation and can, therefore, give them a more beneficial experience. They can help their patients explore a wide variety of treatment options, so they can pick the kind of radiation therapy that’s right for them and their specific conditions.
