This type of catheter is known as a central venous catheter. Sometimes, a central venous catheter is attached to a port, a small plastic or metal container placed surgically under the skin. You will swallow the drug, just as you do many other medications. The medication will be applied onto the skin. Catheters may be placed directly into the spinal fluid, abdominal cavity.
External pumps remain outside of the body.
Some are portable and allow a person to move around while the pump is in use. Other external pumps are not portable and may restrict activity. Internal pumps are placed surgically inside the body. Internal pumps allow people to go about most of their daily activities. Getting chemotherapy by mouth, on the skin, or by injection generally feels the same as taking other medications by these methods.
