In Our Own Words

Chemotherapy is a form of cancer treatment, and chemo drugs work by killing cancer cells or preventing abnormal cells from multiplying. It differs from a localized treatment, like radiation therapy, since it can treat cancer cells anywhere in the body.

Chemotherapy may be prescribed to cure cancer or just to ease symptoms. There are over 100 different types of chemo drugs available to treat cancer. Types of chemotherapy are classified according to their chemical makeup and how they work. Drugs may be used in various combinations depending on the type of cancer being treated and stages of the disease.
