Induction therapy is a type of treatment used in cancer patients to quickly reduce the size of a tumor before undergoing further treatment, such as surgery or radiation therapy. This approach is often used in aggressive forms of cancer where immediate action is needed to shrink the tumor and prevent spreading to other parts of the body. Induction therapy may involve the use of chemotherapy, targeted therapy, or immunotherapy to kill cancer cells or inhibit their growth. The goal of induction therapy is to make the tumor more manageable and increase the likelihood of a successful outcome with subsequent treatments.
