Loss of Normal Growth Control
Cancer arises from a loss of normal growth control. In normal
tissues, the rates of new cell growth and old cell death are kept in
balance. In cancer, this balance is disrupted. This disruption can
result from uncontrolled cell growth or loss of a cell's ability to
undergo "apoptosis." Apoptosis, or "cell suicide," is the mechanism
by which old or damaged cells normally self-destruct.
