Drug therapy, also known as systemic therapy, refers to several types of medication that travel through the bloodstream to attack cancer cells anywhere in the body. You can receive drug therapy orally as a pill or intravenously through an injection or infusion into a vein. Your medical oncologist, a doctor who specializes in anticancer medications, manages your drug therapy.
Drug therapy can treat cancer at any stage anywhere in the body. In general, drug therapy stops the growth of cancer cells by destroying the cells or stopping them from dividing and multiplying.
