Radiation therapy – also called radiotherapy – is a cancer treatment that directs rays of energy to the cancer area. Its goal is to kill or shrink cancer cells.
At OSF Saint Anthony Center for Cancer Care, we rely on the latest proven technologies to deliver radiation therapy as accurately as possible.
Plus, your oncologist and the radiation therapy team at OSF collaborate closely to ensure you get the care you need.
How Radiation Therapy is Used
Radiation may be used after surgery to try to kill any cancer cells that might have been missed or could not be removed during surgery. If surgery is not possible, radiation may be the primary treatment.
Chemotherapy is often given along with radiation.
Palliative radiation helps ease symptoms but doesn’t cure cancer. For example, it can help shrink a tumor that's pressing on nerves or blood vessels.
