Produced in the bone marrow, white blood cells defend the body against infections and disease. An excess of white blood cells is usually due to infection or inflammation.
Cancer immunotherapy (immuno-oncotherapy) is the stimulation of the immune system to treat cancer, improving the immune system's natural ability to fight the disease. [1] It is an application of the fundamental research of cancer immunology ( immuno-oncology ) and a growing subspecialty of oncology .
