What is adjuvant therapy used for?

Risk reduction. The goal of adjuvant therapy is to reduce the risk of cancer returning, and hopefully to prolong life.
Added treatment. Adjuvant therapy means additional therapy. It is therapy given in addition to surgery to remove cancer. Adjuvant therapy can be chemotherapy, radiation therapy, biologic therapy or hormone-blocking therapy. The goal is to kill individual cancer cells that may not have been removed with surgery in order to prevent cancer from recurring.
