The Physics of Radiation Therapy

Radiation therapy uses high-energy rays or particles to precisely target and destroy cancer cells. These rays damage the DNA inside the cells, preventing them from dividing and growing. Since cancer cells are less capable of repairing this damage compared to normal cells, they eventually die. The treatment is carefully planned with advanced imaging to maximize impact on the tumor while minimizing harm to surrounding healthy tissue. Essentially, radiation therapy employs controlled radiation doses to selectively eliminate cancerous cells, aiding in cancer treatment with a balance of effectiveness and safety.
