2 Hospitals For Radiotherapy / Radiology In Tennessee

Radiotherapy / Radiology (click for worldwide facilities list): Radiation therapy, also called radiotherapy or X-ray therapy, involves treating cancer with beams of high-energy particles or waves (radiation), such as x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors.
Radiation can be very helpful in alleviating cancer pain in some circumstances. It can be used to reduce the size of some tumors, which takes pressure off organs and nerves that the tumor touches. It can also be used to treat the pain of cancer that has spread to the bones, the brain, blood vessels, nerves and spine.

There are several types of radiation therapy. They include:

-External beam radiation therapy uses radiation delivered from outside the body that is focused on the cancer.
-Internal radiation therapy, also known as brachytherapy, uses radioactive material placed directly into or near the cancer. Brachytherapy may be used alone or in combination with external beam radiation therapy.
-Intraoperative radiation occurs during surgery. It involves external beam radiation focused directly at the area that needs radiation during an operation.
-Systemic radiation, which involves a radioactive substance that can be injected into a vein. The substance travels throughout the body, delivering radiation.
