Immunotherapy in the treatment of cancer.

This article is a review of immunotherapy in the treatment of cancer incorporating the history of immunotherapy in the nineteenth and twentieth centuries, assessment of the techniques currently in use and of possible future developments. Although immunotherapy is not established as a therapeutic technique, evidence suggests that the immune response does influence the development of neoplastic cells. A better understanding of the immune response and its control may lead to the production of efficacious immunological treatment of certain cancers.
