Chemotherapy given before surgery and/or radiation is called neoadjuvant chemotherapy . Chemotherapy given with radiation or after surgery is known as adjuvant chemotherapy.

How Is Chemotherapy Given?

Chemotherapy drugs can be given in the following ways:

  • By mouth in tablet, capsule or liquid form.
  • Intravenously (often called I.V.) through a vein. A fine needle is inserted into a vein in the hand or lower arm at the beginning of each treatment and removed at the end of the treatment.
  • Intravenously through a catheter. A catheter is a soft, flexible tube that is placed in a large vein and remains there as long as necessary for treatment. The catheter usually is placed in the upper chest. Sometimes a catheter is attached to a "port" - a tiny disk with an opening - that is placed under the skin.
  • Topically . Medication is applied directly onto the surface of the skin.
  • By injection with a needle and syringe.
