In recent years palliative care has emerged as a major public health care issue, both in developed and developing countries. The rising number of cancer deaths as a result of increased tobacco consumption, control of other diseases, lack of preventive programs, and the difficulties of accessing curative treatments in many countries have made palliative care and pain relief the appropriate, and in many cases, the only option for patients with advanced disease. The World Health Organization (WHO) and its Regional Office for the Americas, the Pan American Health Organization (PAHO), have promoted palliative care as a component of their cancer control program. Some health care workers and policy makers are not adequately informed about the role that intergovernmental agencies such as WHO and PAHO play in the health care field. This has led to confusion and, in some cases, misjudgment of the organization. This paper summarizes the structure and role of PAHO and, specifically, its participation in the development of a palliative care program for Latin America and the Caribbean. Many health care professionals, administrators, and policy makers are unaware of the organization 's objectives in this area and the tools available to assist in the implementation and development of national programs to care for patients with advanced cancer: The information in this paper is based on data found in the PAHO and WHO web sites, as well as other technical publications from different sources, including individuals not formally associated with WHO or PAHO.
