Research Summaries for Integrative Therapies

To support informed decision-making, we are committed to developing evidence-based research summaries for selected integrative cancer therapies. These summaries also called monographs, synthesize the safety and effectiveness of some of the more invasive and controversial complementary therapies used in the context of cancer.

Here you will find the research summaries we have published to date. There are patient versions (a quick summary) as well as health professional versions (a longer, fully cited and more detailed summary). We do our best to keep the monographs up to date, however please note that the monographs only encompass information known at the time of writing.
