What Does a Radiation Therapist Do? Unlike radiologic technologists who utilize x-rays for diagnostic purposes, radiation therapists are trained to deliver high doses of ionizing radiation to specific areas of the patientâs body for the treatment of disease, specifically cancer.
Radiation therapy is the use of high-energy x-rays to destroy cancer cells. It is commonly used for treating rectal cancer because this tumor tends to recur near where it originally started. A doctor who specializes in giving radiation therapy to treat cancer is called a radiation oncologist. A radiation therapy regimen, or schedule, usually consists of a specific number of treatments given over a set period of time.
