Induction chemotherapy refers to the initial phase of treatment aimed at reducing the size of tumors or controlling the spread of cancer before any definitive treatment, such as surgery. The primary objective during this phase is to achieve a significant reduction in tumor burden, making subsequent treatments more effective or allowing for surgical removal of the tumor if applicable. This is particularly important in aggressive cancers where prompt intervention can lead to better outcomes.

In contrast, the other options describe different aspects of cancer treatment. Preventive therapies are used to reduce the risk of recurrence after initial treatment. Modalities utilized after surgery focus on eradicating any remaining cancer cells, while supportive care centers on managing symptoms and improving the quality of life for patients undergoing active treatment. Induction chemotherapy specifically targets the aggressive nature of tumors early on, thus distinguishing it from these other approaches.
