Electron Radiation Therapy
radiation therapy primarily focuses on superficial diseases on the skin surface, such as skin cancers, mycosis fungoides and some lymph nodes. Electrons are also quite effective in treating a surgical bed where a tumor was removed (e.g breast)..Since electrons are considered a superficial treatment, maximum penetration occurs only a few centimeters (cm) beyond the skin surface, sparing deeper healthy tissue.
Electrons are particles with a negative charge. Electron beams cannot travel very far through body tissues. Therefore, their use is limited to tumors on the skin or near the surface of the body.
