Chemotherapy is a form of systemic treatment of invasive breast cancer.

Chemotherapy is a cancer treatment that uses drugs to destroy cancer cells. It stops them from multiplying at points in the cells' life cycle. These anticancer drugs work by killing cancer cells that may be in different parts of your body (not just in your breast). Unfortunately, chemotherapy may also affect your healthy cells, which can cause side effects. Because some anticancer drugs work more effectively together than alone, chemotherapy may consist of more than one drug. This is called combination therapy.

CHEMOTHERAPY CAN BE USED:
To attempt to cure cancer
To keep cancer from spreading
To slow cancer's growth or
To relieve symptoms that may be caused by cancer.
