Cancer and the Immune System:
The Vital Connection
We recognize that patients and caregivers looking into cancer immunotherapy
as a potential treatment option often face an uphill battle in understanding
the technical language of immunology. To help explain the science behind immunotherapy, we have prepared this free, downloadable guide:
Cancer and the Immune System: The Vital Connection (12MB PDF).

This ebook will equip you with a basic understanding of cancer biology, how our immune system works, and the range of rapidly developing treatments that fall into the category of immunotherapies as well as definitions for the terminology of immuno-oncology.
