The immune system is the collective army of a trillion white blood cells, the bone marrow, antibodies and the thymus gland that identifies and then destroys the millions of microbes (bacteria, viruses, parasites, fungi) that penetrate our bodies every day. This system also needs to eliminate 500 to 10,000 of our own cells that have become genetically abnormal or cancerous.

Central to the immune system are the lymphocytes which include the T-cells, B-cells and NK cells. These cells are able to identify and destroy almost every intruder or infected/cancerous cell in the body. NK cells are of particular importance because they are able to work more or less independently, without special instructions from the immune system, to recognize and destroy many types of cancerous cells.
They are therefore considered the body’s first line of defense against cancer.~cancer active
