Question

A patient is receiving treatments for brain cancer. Which electromagnetic waves are most likely being used as part of the treatment?

infrared
ultraviolet
microwave
gamma ray

Answer 1

In the treatment of brain cancer, the electromagnetic waves that are most likely being used are **gamma rays**. Gamma rays are a form of high-energy radiation typically used in radiotherapy to target and kill cancer cells. Radiotherapy may involve emitting gamma rays from a machine or using radioactive sources that emit gamma radiation directly at the tumor. Other forms of electromagnetic waves like infrared, ultraviolet, and microwaves are not standard treatments for cancer.
