What is Radiation Therapy?
Radiation therapy is a treatment procedure which uses high energy radiation to kill cancer cells and to shrink tumors. The killing of cancer cells are carried out by creating charged particles inside the DNA to damage the DNA of the cell or by directly damaging the DNA. This therapy can damage cancer cells as well as normal cells, if not carried out carefully.
