What differentiates radiation therapy from chemotherapy?

Radiation therapy is distinguished by its use of high-energy rays, such as X-rays or gamma rays, specifically to target and destroy cancer cells within defined areas of the body. This targeted approach allows for concentrated doses of radiation to be delivered to the tumor while aiming to minimize damage to surrounding healthy tissue. It is commonly employed for localized cancers, making it highly effective for treating specific tumors or areas where cancer is present. Chemotherapy, in contrast, often works systemically by using chemical substances that can affect the entire body, which can treat cancer that has spread (metastasized) or is at risk of spreading. While some chemotherapy regimens may be used in conjunction with radiation therapy for enhanced effectiveness, chemotherapy typically does not rely on high-energy rays. The understanding of these mechanisms is crucial in cancer treatment as it informs decisions about the best course of action based on the type, location, and stage of cancer.
