Question

Electron beam therapy is a kind of radiation therapy intended to treat ?

• A. Enlarged prostrate gland.
• B. Gall bladder stones by breaking them.
• C. Certain types of cancers
• D. Kidney stones

Answer 1

The correct option is C Certain types of cancers

Electron therapy or Electron Beam Therapy (EBT) is a kind of external beam radiotherapy, where electrons are directed to a tumor site. Electron beam therapy is performed using a medical linear accelerator. The same device can also be used to produce high energy photon beams. When electrons are required, the x-ray target is retracted out of the beam and the electron beam is collimated with a piece of apparatus known as an applicator or an additional collimating insert, constructed from a low melting point alloy. Electron beam therapy is used in the treatment of superficial tumors like cancer of skin regions, or total skin (e.g., mycosis fungoides), diseases of the limbs (e.g., melanoma and lymphoma), nodal irradiation, and it may also be used to boost the radiation dose to the surgical bed after mastectomy or lumpectomy.

So, the correct answer is 'Certain types of cancers'
