A chemotherapy port can be placed into the chest under the skin to allow chemotherapy medications to be given without repeated needle sticks. This device is typically called a Port-a-cath and can be used to give intravenous fluids, medications, and chemotherapy drugs into a large vein. Radiation is energy directed through a beam and does not require port access. A port film is a term used to describe a precise location using x-ray guidance to deliver radiation.
