Is the cancer cells? In general, cancer cells are defined as abnormal cells, which grow and multiply rapidly and uncontrollably. Cancer cells do not care about the limitations of nutrients, space and the fact that they must share with normal cells that are nearby. Furthermore, they ignored orders to stop breeding by the body concerned.
Normal body cells also grow, divide and at a certain moment they will die. But in cancer cells, they continue to grow, reproduce themselves and try to avoid death (apoptsis), worse speed far exceeding the growth of cancer cells to normal cells.
