Radiation Oncology

A radiation oncologist is a physician who specializes in using radiation to treat cancer. Treatment with radiation is provided by a team of radiation oncologists, dosimetrists, radiation therapists, and physicists.   

Radiation therapy is the use of high-energy x-rays or radioactive materials to kill cancer cells. This radiation injures the cancer cells so that they can no longer continue to divide and multiply. Each treatment causes more cells to die, reducing the size of the cancerous tumor. Radiation therapy incorporates various techniques, including external beam and or internal radiation. The treatment is odorless and invisible.  

Your oncologist will determine if your treatment plan will include radiation therapy. Radiation oncology is available at our St. Paul Cancer Center and Maplewood Cancer Center locations.
