Immunotherapy
Immunotherapy stimulates the body’s normal defence mechanisms, so that it can use the immune system to fight the malignant process and destroy the tumour.
Malignant tumours in man are not greatly immunogenic. That is to say that they are not generally recognised as foreign by the body, so that they are tolerated and can grow. It is, therefore, necessary to stimulate body defence mechanisms by means of various agents, such as interferon and interleukin and other immunotherapeutic agents which are in the course of development.
