Fast Neutron Therapy

Fast neutron therapy is a type of radiation therapy used in the treatment of certain types of cancer. It utilizes high-energy neutrons to destroy cancer cells.

Pronunciation

Fast Neutron Therapy: /fɑːst 'njuːtrɒn θɛrəpi/

Etymology

The term "Fast Neutron Therapy" is derived from the English language. "Fast" refers to the high speed of the neutrons, "Neutron" is a subatomic particle with no net electric charge, and "Therapy" refers to the treatment intended to relieve or heal a disorder.

Definition

Fast neutron therapy is a type of particle therapy that uses a beam of neutrons to kill cancer cells and shrink tumors. The neutrons used in this therapy are of high energy, typically above 10 MeV.

Application

Fast neutron therapy is often used to treat certain types of tumors that are radio-resistant to low-LET (Linear Energy Transfer) radiation such as photons or protons. These include certain types of salivary gland cancer, adenoid cystic carcinoma, and certain types of soft tissue sarcoma.

Advantages and Disadvantages

The main advantage of fast neutron therapy is its ability to treat radio-resistant tumors. However, it also has a higher risk of causing damage to normal tissues compared to other types of radiation therapy.
