Radiation Therapy Explained

This cancer treatment targets cancer cells with
high-frequency energy. The energy destroys the
DNA of the cancer cells. It kills cancer cells, and
can shrink tumors. Radiation therapy can be
combined with other treatment options such as
chemotherapy or surgery as part of a complete
treatment plan.If you would like to know if your

There are many types of radiation therapy, and
many ways to administer them. Your doctor will
choose the type that is most effective for your
particular cancer. Let's look at the main types and
learn about the different ways radiation therapy
may be delivered.

The first type is called external-beam radiation
therapy. It targets your cancer with high-frequency
energy. X-rays, gamma rays, protons or beams of
electrons may be used. The beam of radiation can
be very precise, allowing your doctor to hit a very
small target.

The second type is called internal radiation therapy.
It is also known as brachytherapy. With this
therapy, the radiation source is implanted in your
body. The source can be radioactive pellets, wires
or some other implant device. These are placed
into your body through a needle or catheter and
positioned next to your tumor. Radiation is slowly
released into the surrounding tissue. Depending on
the radiation dose needed, a radioactive implant
may be left in place or removed after a period of
time.

The third type of radiation therapy is called
systemic radiation therapy. With this therapy, you
either swallow a radioactive substance or have it
injected into your body. The radiation travels
through your body. It comes into contact with the
cancer cells, destroying them. While you are being
treated, you need to take special care to avoid
exposing others to radiation. You may be isolated in
the hospital for a few days. Soon after your
treatment, your body will flush out the radiation
through your urine. After a short period of time, you
will no longer be a danger to others.

Talk to your doctor about whether radiation therapy
should play a role in your cancer treatment.
