Neutron-based radiation therapy, often referred to as neutron therapy or neutron beam therapy, is a specialized form of radiation therapy used in cancer treatment. Unlike conventional photon-based radiation therapy, which uses high-energy photons (X-rays or gamma rays), neutron therapy employs neutrons to deliver radiation to tumors. Neutrons have unique properties that make them particularly effective against certain types of cancer, especially those with high oxygen levels and high radiosensitivity.

The process of neutron therapy involves the use of a particle accelerator to generate a beam of neutrons. These neutrons are then directed towards the tumor, where they interact with the tumor cells, causing DNA damage and ultimately leading to cell death. The depth of penetration of neutrons is greater than that of photons, allowing for more precise targeting of deep-seated tumors. Additionally, neutrons have a higher relative biological effectiveness (RBE) compared to photons, meaning they are more effective at killing cancer cells.

Neutron therapy is particularly beneficial for certain types of cancer, such as glioblastoma, which is a type of brain cancer. The high oxygen levels in these tumors make them more radiosensitive to neutrons, increasing the likelihood of successful treatment. However, neutron therapy is not suitable for all types of cancer and is typically reserved for cases where conventional treatments have failed or are not an option.

The use of neutron therapy is limited by its high cost and the need for specialized infrastructure, including particle accelerators. Despite these challenges, ongoing research and advancements in technology are aimed at making neutron therapy more accessible and effective for a broader range of cancer types.
