Unlike chemotherapy drugs, targeted therapies usually do not attack normal cells in the body.
Chemotherapy is considered a systemic therapy in the treatment of breast cancer. It is most often given as an adjuvant therapy after surgery, but can also be given before surgery (or neoadjuvantly). Chemotherapy is also often used to treat breast cancer that has recurred or spread.

It is most often given intravenously through a port-a-catheter, a catheter that is inserted into a large vein leading to your heart and implanted under the skin to provide easy access for both chemotherapy and blood tests. Some chemotherapy drugs, however, do come in pill form.
Usually chemotherapy is given in cycles with time to recover between treatments. The type of chemotherapy drug your medical oncologist prescribes will determine how long each cycle will be. Some drugs are given only once every 2 to 3 weeks, others are given daily for a week or two, and still others are given weekly.
