PCC Radiation Oncology
(765) 662-4293


Radiation oncology is a medical specialty dealing with the use of various forms of radiation in treating cancer. Treatments prescribed by radiation oncologists are delivered by a multidisciplinary radiation therapy team including a radiation physicist, dosimetrist, radiation therapists and radiation therapy nurse.

Progressive Cancer Care provides radiation oncology services with physicians from Indiana Radiotherapy, P.C. Our center is equipped with a Varian Clinac iX linear accelerator that has IMRT capabilities. In addition, the center is equipped with a Siemens CT/Simulator so the patient will not have to leave the building to have simulations performed.

What is IMRT?

IMRT allows very precise external beam radiotherapy treatments. Rather than having a single large radiation beam pass through the body, with IMRT the radiation is effectively broken up into thousands of thin radiation beams, providing accuracy so that all beams intersect on the cancer, minimizing harm to surrounding tissues.

What is Brachytherapy?

Brachytherapy (also called internal radiation) is a way to administer radiation therapy for treating cancers. It uses radioactive materials placed very close to tumors to kill cancer cells while minimizing damage to normal tissues.

There are two main subtypes of brachytherapy. Interstitial radiation therapy places radioactive material into tissue, within or near the cancer. Intracavitary radiation therapy places the radioactive material into a body cavity (such as the chest cavity, abdominal cavity or vagina) near a cancer. In contrast, external beam radiation therapy or teletherapy uses radiation delivered to a cancer from outside of the body.
