Radiation therapy
Radiation therapy (also called radiotherapy) is
a cancer treatment that uses high doses of
radiation to kill cancer cells and shrink tumors.
At high doses, radiation therapy kills cancer
cells or slows their growth by damaging their
DNA. Cancer cells whose DNA is damaged
beyond repair stop dividing or die. When the
damaged cells die, they are broken down and
removed by the body.

7. Microsurgery involves the use of
a high-powered microscope
during surgery, which allows the
surgeon to obtain a magnified
view of the surgical field.
Microsurgery is widely used for
brain tumor surgery.
