This varies depending on the particular type of biologic therapy being used. Therapies may be given by mouth, into a vein (intravenously) or by injection, either under the skin (subcutaneous) or into a muscle (intramuscular). Therapies may also be given directly into a body cavity to treat a specific site. For example, gene therapy directed against mesothelioma (a type of lung cancer) may be injected directly into the lung. Some of these therapies are approved by the U.S. Food and Drug Administration, but many are still being tested in clinical trials. Depending on the type of cancer and how far it has spread, some patients may only need biologic therapy, while others may receive this in conjunction with other therapies ( chemotherapy, surgery, or radiation therapy).
