What is the typical method of administering chemotherapy?

The typical method of administering chemotherapy is intravenously (IV) because this route allows for the rapid and effective delivery of chemotherapy drugs directly into the bloodstream. IV administration ensures that the medication can circulate throughout the body quickly, reaching cancer cells in various tissues and organs. This method is particularly important for aggressive cancers that require immediate systemic treatment.

In contrast, while oral chemotherapy is also used for some agents, it may not be suitable for all patients or types of cancer, and absorption can vary between individuals. Intramuscular and topical routes are rarely used for chemotherapy due to limitations in absorption and efficacy for systemic treatment. Thus, intravenous delivery is preferred in oncology for the majority of chemotherapy regimens.
