Részecsketerápia

Részecsketerápia, also known as particle therapy, is a type of radiation therapy used to treat cancer. Unlike conventional photon radiation therapy, which uses X-rays, particle therapy uses beams of protons or heavier atomic nuclei, such as carbon ions. These particles have unique physical properties that allow for a more precise delivery of radiation to the tumor while minimizing damage to surrounding healthy tissues.

The key advantage of részecsketerápia lies in the Bragg peak phenomenon. As charged particles travel through tissue, they deposit most of their energy at a specific depth, with minimal energy deposited before and after that point. This allows oncologists to precisely target the tumor's location and shape, effectively stopping the tumor's growth or destroying cancer cells. This targeted approach can lead to fewer side effects compared to standard radiation treatments.

Részecsketerápia is particularly beneficial for treating tumors that are close to critical organs or structures, such as those in the head and neck, spine, or brain. It is also considered for certain pediatric cancers and other complex tumors where precision is paramount. The treatment involves multiple sessions, typically on a daily basis over several weeks. While it is a highly advanced form of cancer treatment, its availability is more limited than conventional radiotherapy due to the specialized equipment and facilities required.
