Cancer is the growth of abnormal cells in a part of the body that begin to grow out of control. There are many different types of cancers but this is how they all begin.
Healthy normal body cells grow, divide, and die. The early years of a person’s life the normal cells will divide rapidly until the person reaches adulthood. During adulthood cells in most parts of the body will divide in order to only replace worn-out, dying, or to repair injuries.
Cancer cells are different from normal healthy cells because they continue to grow and divide. Cancer cells do not die; they outlive the normal cells and will continue to form new abnormal cells.
