CHEMOTHERAPY

HOW DOES CHEMOTHERAPY WORK?

Chemotherapy medicines prevent cancer cells from growing and spreading by destroying the cells or stopping them from dividing. Cancer cells tend to grow and divide very quickly with no order or control. Because these cells are growing at such a rapid pace, at times they may break away from the original tumor and travel to other parts of the body. Chemotherapy weakens and destroys cancer cells at the original tumor site and throughout the body.

Most normal cells grow and divide in a precise, orderly way. Still, there are some normal cells that do divide quickly, including cells in hair follicles, nails, the mouth, digestive tract, and bone marrow. (Bone marrow makes blood cells.) Unfortunately, chemotherapy can also harm these other types of rapidly dividing cells, possibly causing negative side effects.

 

WHEN IS CHEMOTHERAPY USED?

Chemotherapy is used to treat:

  • Early-stage invasive breast cancer to get rid of any cancer cells that may be left behind after surgery and to reduce the risk of the cancer recurring

  • Advanced-stage breast cancer to destroy or damage the cancer cells as much as possible

When treating early-stage breast cancer, it’s fairly common for chemotherapy to be given after surgery, as soon as you recover. Doctors call this “adjuvant” chemotherapy because it is administered in addition to surgery, which is considered the primary treatment. In some cases, chemotherapy is given before surgery to shrink the cancer so that less tissue needs to be removed. When chemotherapy is administered before surgery, it is called “neoadjuvant” chemotherapy.

In many cases, chemotherapy medicines are given in combination, which means you get two or three different medicines at the same time. These combinations are known as chemotherapy regimens. In early-stage breast cancer, standard chemotherapy regimens lower the risk of the cancer recurring. In advanced breast cancer, chemotherapy regimens can make the cancer shrink or disappear in about 30-60% of people treated. Keep in mind however, that every cancer responds differently to chemotherapy.
