Cancer Immunotherapy at a Crossroads

It was in 1909 that Nobel Prize-winning German physician Paul Ehrlich proposed the idea that our bodies are fighting constant battles with cancer and that, thankfully, most of the time we win.

Ehrlich was a visionary in recognizing the interaction between cancer and the immune system. Specifically, that cancerous cells are continuously arising in the body but that our immune defenses in many if not most cases keep them at bay.
