There are many types of immunotherapy. Immunotherapy can be divided into four broad categories:
Vaccines: Vaccination involves injections of proteins or processed tumor cells in combination with immune stimulating proteins and laboratory prepared cells to induce an immunization to the cancer cells.
Cell-based: Cell-based therapies usually involve growth and modification of immune cells outside of the body.
Antibody-based: Anti-body based therapies involve the infusion of monoclonal antibodies or related proteins
Combination treatments: More recently, there are combinations and antibody-based therapies that involve all of the components.
