What is Radiation Therapy?

Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells. Special equipment is used to send high doses of radiation to the cancer cells or tumor. This keeps the cells from growing and making more cancer cells.

Radiation therapy damages cells by destroying the genetic material that controls how cells grow and divide. Radiation can also affect normal cells near the tumor, but normal cells can repair themselves while cancer cells cannot. Our goal is to destroy as few healthy cells as possible. And we offer many technologies that help us eliminate the instances of radiation hitting healthy cells.

At the UMC Southwest Cancer Center, we offer both external beam radiation and internal radiation therapy. External beam radiation comes from a machine outside the body. Internal radiation therapy is given through a radiation source that is put inside you (an implant). This allows the doctor to give a large dose of radiation directly to the cancer cells. Whichever method is used, you are receiving top-notch care, personalized to you.
