Chemotherapy drugs can be given in a variety of different ways.
During this testing process, scientists and doctors determine how specific chemo drugs are absorbed in the body and how they work. Sometimes stomach juices can destroy different chemicals, making some medications impossible to give as a pill. Other substances are found to have better anti-cancer action if given intravenously (needle in the vein). Some medications can be given as an injection into the muscle and still others are absorbed when given directly into the bladder or the abdominal cavity.
