Radiation therapy uses high energy x-rays to damage cancer cells
and stop them from growing. The strength of the x-rays used in
radiation therapy is significantly stronger than that of a
normal chest x-ray. The strength of these rays destroys a cell’s
ability to reproduce. There are two types of radiation therapy,
and some people receive both types. They are: External beam
radiation therapy —The rays are directed at the affected area
from the outside of your body. This procedure is like having an
x-ray. If you receive external radiation therapy, you will go to
the hospital or clinic each day for treatment. Usually,
treatments are given 5 days a week for 5 to 6 weeks. At the end
of the treatment, the tumor site often gets an extra dose of
radiation. Implant/internal radiation —This treatment gives
additional, high-dose radiation directly to the area affected by
the cancer. A capsule containing radioactive materials is placed
directly into the cervix and another carrier may be placed in
your vagina against the
