Chemotherapy (also called chemo) is a type of cancer treatment that uses
drugs to destroy cancer cells.
How Does Chemotherapy Work?
Chemotherapy works by stopping or slowing the growth of cancer cells, which
grow and divide quickly. But it can also harm healthy cells that divide quickly,
such as those that line your mouth and intestines or cause your hair to grow.
Damage to healthy cells may cause side effects. Often, side effects get better
or go away after chemotherapy is over.
