What specific approach does radiation therapy employ against cancer?

Radiation therapy specifically employs high energy particles or waves to target and destroy cancer cells. This method utilizes ionizing radiation, which can penetrate tissues and disrupt the DNA of cancer cells, inhibiting their ability to divide and grow. The decay of high-energy particles or waves generates energy that can be focused precisely on the tumor, allowing for effective treatment while minimizing damage to surrounding healthy tissues.

This targeted approach is essential in oncology, as it can be applied to various types of cancers and is often used in conjunction with other treatment modalities, such as surgery or chemotherapy, to enhance overall effectiveness. Understanding this mechanism is crucial for effective cancer management and treatment planning.
