• What is 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 low doses, radiation is used in x-rays to see
inside your body, as with x-rays of your teeth or
broken bones.

• TYPES OF RADIATION THERAPY

5

• External Beam Radiation Therapy

External beam radiation therapy uses high doses
of radiation to destroy cancer cells and shrink
tumors. A large machine aims radiation at the
cancer. The machine moves around you, without
touching you. Most treatments last from 2 to 10
weeks.

• Types

• Photons
• Protons
• Electrons

6

• Brachytherapy

Brachytherapy allows doctors to deliver higher
doses of radiation to more-specific areas of the
body, compared with the conventional form of
radiation therapy (external beam radiation) that
projects radiation from a machine outside of your
body.

• Used to Treat

• Endometrial cancer
• Esophageal cancer
• Eye cancer
• Head and neck cancers

Advantage for the Patients

• The main advantage of radiotherapy is that it may
  help to control the growth of cancer.

• You may be able to carry on with your daily life,
  such as going to work, if you feel up to it.

• If you have advanced cancer, radiotherapy can
  help control symptoms and relieve pain.

• Disadvantages for the Patient

• Radiotherapy can cause side effects, including
  tiredness, sickness and runny poo (diarrhoea).
• If you have chemoradiotherapy, you may get side
  effects from the chemotherapy.
• If you have borderline resectable cancer and
  locally advanced pancreatic cancer, you may have
  to go to the hospital five days a week for your
  treatment, although this may vary.
