Much like other forms of radiation therapy, electron therapy treats cancer by damaging the DNA of cancerous cells. The aim of this method is to damage as many cancerous cells as possible while minimizing damage to healthy, normal cells.
Electron beam radiation consists of tiny electrically charged particles (electrons) which are generated by a linear accelerator. The linear accelerator can then deliver doses to the area which is being treated. Electrons do not penetrate deep into tissue, so the radiation exposure to deep tissues is minimal.
Electron Therapy Can Treat:
Electron therapy can be used in conjunction with other types of treatment. Electron therapy may be used as a ‘booster dose’ of radiation for areas that have been treated by another form of radiotherapy, or where a tumor was removed in order to prevent recurrence.
What to Expect Treatment:
Electrons only penetrate the skin and do not go deep into tissue, so the radiation dose to deep tissue is minimal. You may experience side effects following treatment. Your radiation oncologist or nurse will go over potential side effects, and will always be happy to address any questions or concerns you may have.
