Cancer: Immune pact with the enemy

Cornelis J. M. Melief1

Progress comes from the latest investigations into a long-standing question in immunology — the role of the immune system in maintaining small, potentially cancerous lesions in a state of dormancy.

The current belief about treating cancer is that tumour cells need to be eradicated as quickly as possible, so as to halt tumour growth and spread, and to prevent or delay the death of the patient. The startling results of Koebel et al.1 (page 903 of this issue) demonstrate that considering cancer as a fatal disease is not always appropriate*.
