The American Cancer Society defines oral chemotherapy as any drug that is taken by mouth to treat cancer. The majority of chemotherapy drugs are administered intravenously, but the oral chemotherapeutic drugs are just as effective. Since most drugs are not given in oral form, not all types of cancer have oral chemotherapies available. Not all chemotherapy drugs, oral or intravenous, are taken on the same schedule, and your doctor will tell you when to take the medications prescribed to you.
