Natural protection: The question is not clear. Natural killer cells act against abnormal cells and do not require prior exposure to the inciting antigen to be effective. Researchers have been trying to improve the number and capabilities of natural killer cells in the treatment of cancer, but this modality has not yet become main stream.

Immunology: Your immune system helps to protect against cancer. One mechanism is through specialized cells, called "natural killer" (nk) cells.

Cells that kill.: These are cells of the immune system that kill other cells that represent a danger to the body, like virally infected cellls and cancer cells. They have a natural ability to recognize stressed cells and can kill these without need of antibody or major histocompatability complex alteration to prime them, hence their name. Thus, they can present a much faster response than other immune cells.

Immune cells: Natural killer cells are immune effector cells that are efficient in killing virus infected cells. They can be divided into 2 sets: CD56bright (produce antiviral agents and help a subset of T cells) and CD56dim (fully mature, can destroy antibody targeted cells). There is a 3rd, dysfunctional subset that has been described in HIV.
