How radiation oncology can help:

  • Highly targeted radiation kills tumors.
  • Maximum radiation is focused directly at the tumor and neighboring tissues which are high risk for containing tumor cells, resulting in less impact on healthy tissues and organs and less side effects.
  • Radiation may be used with other innovative treatments, like chemotherapyhormone therapy and immunotherapy, to fight against the growth of new cancer cells.
