What term describes the process of using radiation to treat cancer?

Radiation therapy specifically refers to the medical treatment that employs high doses of radiation to kill cancer cells and shrink tumors. This treatment targets the genetic material within the cells, disrupting their ability to divide and proliferate. It can be used as a standalone treatment or in conjunction with other modalities such as surgery or chemotherapy, depending on the specific type and stage of cancer.

On the other hand, radiologic imaging focuses on techniques used to visualize the internal structures of the body for diagnostic purposes, while diagnostic radiography specifically refers to the creation of images using radiation to diagnose health conditions. Interventional radiology involves minimally invasive procedures guided by imaging techniques, but it is not primarily dedicated to treating cancer with radiation. Thus, the term that accurately describes the process of using radiation as a treatment for cancer is indeed radiation therapy.
