Which of the following is a primary goal of radiation therapy?

The primary goal of radiation therapy is to control tumor growth. Radiation therapy uses high doses of radiation to kill cancer cells or to inhibit their ability to grow and divide. By precisely targeting tumors, radiation can shrink or eliminate malignant cells while minimizing damage to surrounding healthy tissue. This targeted approach is essential in managing and reducing the size of tumors, making it a cornerstone treatment in oncology for various types of cancer.

While other treatments may focus on enhancing the immune response, increasing blood flow, or promoting tissue regeneration, the central purpose of radiation therapy is explicitly about controlling and reducing the malignancy of tumors to achieve better patient outcomes.
