Your immune system can recognize cells based on the proteins
present on the surface of cells. Viruses, bacteria, and other foreign
cells are recognized as being different from your own cells and are
How does your immune system know which cells to attack and attacked by your immune system. Sometimes, one of your own
which cells are part of your own body? cells changes, or mutates, giving the cell the ability to multiply
continuously. Such mutations often are the cause of cancer. Your
immune system has the ability to recognize mutated cells and
attack them before they can grow into a tumor.
