Electron beams are streams of electrons that are used in various medical applications, most notably in the field of radiation therapy for cancer treatment. Here are some key aspects of electron beams in medical applications: ### 1. **Radiation Therapy**: - **Superficial Tumors**: Electron beams are particularly effective in treating superficial tumors, such as skin cancers or tumors located just beneath the skin.
External beam radiotherapy (EBRT) is a method of delivering radiation treatment to cancer patients. It involves directing high-energy beams of radiation from outside the body towards the tumor. The purpose of EBRT is to destroy cancer cells or inhibit their growth while minimizing damage to surrounding healthy tissue.
Intraoperative electron radiation therapy (IOERT) is a specialized form of radiation therapy that is delivered to a tumor during surgical procedures. This technique allows for direct radiation treatment to the cancerous tissue while minimizing exposure to surrounding healthy tissues. Here are some key features of IOERT: 1. **Timing**: IOERT is administered while the patient is still undergoing surgery, often after the tumor has been removed and before the surgical site is closed.
