What is immunotherapy?

Immunotherapy is a treatment strategy that utilizes the patient's own immune system, selectively modulating and stimulating immune cells to treat diseases. It aims to activate the cellular immune system to effectively resist cancer cell proliferation and induce an immune response against specific antigens. Immunotherapy enhances the body's immune system in fighting pathogens and effectively suppresses cancer progression by inhibiting cancer cells. Main approaches in immunotherapy include immune activation, immune modulation, immune enhancement, and immune suppression. Its mechanism of action differs from that of traditional anticancer drugs, making it a unique approach to cancer treatment. It can block cancer cell proliferation, inhibit tumor-associated T cells within the immune system, and induce immune responses against cancer antigens. With broad applications, immunotherapy can be used in the treatment of malignant tumors such as leukemia and lymphoma.
