Charged particle therapy (tʃɑːrdʒd ˈpɑːtɪkl ˈθɛrəpi) is a type of cancer treatment that uses particles with an electric charge to destroy cancer cells. The spelling of the word "charged" is pronounced as tʃɑːrdʒd with a soft "ch" sound, followed by "ar" sound and the "dʒ" sound. The word "particle" is pronounced as ˈpɑːtɪkl with emphasis on the first syllable and a soft "t" sound. The pronunciation of the word therapy is ˈθɛrəpi with emphasis on the second syllable and the "r" sound followed by the "i" sound.
Charged Particle Therapy refers to a specialized form of cancer treatment that utilizes high-energy particles, such as protons or carbon ions, to target and destroy cancer cells. This therapy is based on the fundamental principles of particle physics and radiation oncology.
Unlike traditional radiation therapies like X-rays or gamma rays, which deliver radiation using photons, charged particle therapy employs particle beams that carry an electric charge. Protons and carbon ions are the most commonly used charged particles due to their precise properties that allow for superior targeting and depth control.
The treatment procedure involves accelerating the particles to high speeds using particle accelerators or cyclotrons. The charged particle beam is then delivered to the tumor site, where it deposits energy along its path, causing damage to the DNA of cancer cells. The charged particles are highly effective in sparing healthy surrounding tissues, as they can be precisely controlled to target the tumor with great accuracy and minimal damage to nearby organs.
Charged particle therapy offers several advantages over conventional radiation therapies. It has the potential to deliver higher doses of radiation to the tumor while minimizing side effects on healthy tissues. Moreover, it is particularly beneficial for treating tumors that are located near critical structures or in pediatric patients, where reducing radiation exposure to healthy tissues is crucial.
Although charged particle therapy requires specialized facilities and equipment, it has shown promising results in providing precise and effective cancer treatment. Researchers continue to explore its potential applications and refine the techniques to improve outcomes for cancer patients.
