‘CAM-Cancer’ is the name of a project entitled ‘Concerted Action for Complementary and Alternative Medicine Assessment in the Cancer Field’ (CAM-Cancer). The CAM-Cancer website (<http://www.cam-cancer.org>) is an open-access information resource on CAM for cancer. It provides synthesised evidence-based information for healthcare professionals drawing on the current research status of the efficacy/effectiveness and safety of CAM for cancer. The information is presented as ‘CAM-summaries’, which are short and concise documents presenting background information as well as an appraisal of the evidence of efficacy and safety. CAM-summaries are peer-reviewed and annually updated. The fully documented and published methodology ensures that CAM-summaries are written in an independent and non-judgemental way to maximise their use amongst health professionals. The project is led by an international panel of experts in cancer care and/or CAM research, and supported by a wide network of professionals and cancer organisations. Originally funded by the European Commission within the Fifth Framework Programme, it is now managed by the National Research Center in Complementary and Alternative Medicine (NAFKAM) at the University of Tromsø, Norway. The project is entirely non-profit and receives no commercial funding.
