Heavy ion therapy is a type of cancer treatment that uses charged particles, such as carbon ions, to target and destroy tumor cells. Unlike traditional X-ray radiation therapy, heavy ions can penetrate deeper into tissues and deliver more energy directly to the tumor while minimizing damage to surrounding healthy cells. This precision makes it particularly effective for certain types of cancers. The therapy is typically delivered using a specialized machine called a particle accelerator. Patients undergo a series of treatment sessions, where the heavy ions are directed at the tumor from different angles. This method is gaining attention for its potential to improve outcomes for patients with hard-to-treat cancers.
