Electron beam

Electron Beam is a type of radiation therapy that uses high-energy electrons to treat cancer. This therapy is often used to treat tumors that are located close to the surface of the body, as the electrons do not penetrate deeply into tissues.

Overview

Electron beam therapy (EBT) is a type of external beam radiation therapy (EBRT). It uses a machine called a linear accelerator to produce a beam of high-energy electrons. The beam is directed at the tumor, where it damages the DNA of the cancer cells and prevents them from dividing and growing.

Treatment Process

Before treatment begins, a radiation oncologist will use imaging tests such as CT scans or MRI scans to determine the exact location and size of the tumor. The patient is then positioned on a treatment table, and the linear accelerator is adjusted to aim the electron beam at the tumor. The treatment is painless and usually takes only a few minutes.

Side Effects

Like all forms of radiation therapy, electron beam therapy can cause side effects. These may include skin reactions, fatigue, and hair loss in the area being treated. Most side effects are temporary and can be managed with medication or other treatments.

Advantages and Disadvantages

One of the main advantages of electron beam therapy is that it can be used to treat tumors that are close to the surface of the body without damaging deeper tissues. However, it is not suitable for treating tumors that are located deep within the body.
