Abstract

Provided are a tumour immunogen, a preparation method therefore, and an application. After localised sequential cooling-heating treatment is performed on tumour tissue and/or cells, the tumour tissue and/or cells release a large amount of tumour immunogen heat shock protein 70. The obtained tumour immunogen can activate the body's tumour immune system, to convert immunosuppressive cells into mature dendritic cells, thereby increasing immunogen presentation, and activating tumour immunity.
