Adjuvant therapy serves a critical role in cancer treatment by enhancing overall treatment effectiveness and preventing recurrence of the disease. It is typically administered after the primary treatment, such as surgery, to remove any remaining cancer cells that might not have been eliminated during the initial intervention. The goal is to lower the risk of cancer returning, thereby improving long-term outcomes for the patient.

This approach is based on the understanding that small numbers of residual cancer cells may persist after surgery, and by using additional therapies like chemotherapy, radiation, or immunotherapy, the likelihood of these cells proliferating and leading to a recurrence can be significantly reduced. By complementing the primary treatment, adjuvant therapy aims to provide a more comprehensive management strategy for cancer, ultimately contributing to better survival rates and improved patient prognosis.
