How does chemotherapy works?

Chemotherapy stops cells from growing. Both cancer cells and normal cells can be affected.
Fortunately most cells in the body are unaffected by chemotherapy.
The cells in the body which grow quickly
may be more affected by chemotherapy.
This is why some patients may lose their hair,
has a sore mouth or has a fall in the number of their blood cells.
Chemotherapy has the advantage in that it travels
around the body via the blood stream.
It can attack and kill cancer cells in different parts of your body
even though they may be too small to be seen.
Most normal cells, even though damaged, are able to grow back again
whereas the damaged cancer cells are less likely to grow back.
