Radiation therapy helps to shrink tumors and kill cancer cells using high energy radiation. Radiation can be delivered outside the body by a machine, or it may be induced near cancer cells using radioactive material. Systematic radiation therapy uses substances such as radioactive iodine which travels in the blood to kill the cancer cells.

Radiation therapy is meant to damage the DNA of cancer cells. It can directly damage the DNA or create free radicals in the cells that will destroy the DNA. When damaged cells die, the body’s natural process breaks them down and eliminates them. Radiation therapy is a treatment option for various forms of cancer including breast cancer and can be used alone or in combination with chemotherapy, surgery or both.

There are many ways in which radiation therapy is conducted, which are beneficial to particular malignancies:

  • Radiation therapy with Intensity-Modulated Radiation Therapy (IMRT) delivers high doses of radiation without damaging healthy cells and tissues near the infected area. The process combines radiation with computer imaging technology to pinpoint tumor locations and deliver beams of radiation. It is the most effective form of radiation therapy that has fewer side effects and complications.
  • Radiation therapy with Image-Guided Radiation Therapy (IGRT) uses the IMRT technology to determine the location of the tumor. IGRT uses advanced technology to monitor the movement of the tumor daily to adjust the beams of radiation to target the precise location.
  • Stereotactic body radiation therapy (SBRT) is a newer technology where biological doses of radiation are delivered directly to the tumor at stronger levels to eradicate cancer cells without exposing healthy organs and tissues. The cure rates with SBRT are higher with minimal side effects.

Radiation oncology technology is continually improving. Its recent advances have seen patients receiving high cure rates and fewer side effects. The treatments have been shorter, with improved quality of life. The new technology provides tumors in three-dimensional images that target radiation beams precisely to the cancer and limit damage to adjacent organs. Investigative drugs under clinical trials will help to destroy cancer cells with radiation therapy.
