C
Passive immunotherapy
D
Anti-angiogenic drugs
Verified step by step guidance1
Understand the different types of cancer therapies: Chemotherapy uses drugs to kill cancer cells, Surgery involves physically removing the tumor, Anti-angiogenic drugs inhibit the growth of new blood vessels to the tumor, and Passive immunotherapy involves introducing antibodies to target cancer cells.
Focus on Passive Immunotherapy: This therapy uses laboratory-made antibodies to bind to specific antigens on cancer cells, marking them for destruction by the immune system.
Recognize the role of antibodies: In passive immunotherapy, antibodies are designed to recognize and attach to specific proteins on the surface of cancer cells.
Consider the mechanism of action: Once the antibodies bind to the cancer cells, they can either directly inhibit the cancer cell's function or recruit other parts of the immune system to attack the cancer cells.
Conclude that Passive Immunotherapy is the therapy that introduces antibodies into the tumor to target cancer cells, distinguishing it from other therapies like chemotherapy, surgery, and anti-angiogenic drugs.
