The International Agency for Research on Cancer (IARC) is the specialized cancer agency of the World Health Organization. The objective of IARC is to promote international collaboration in cancer research. The Agency is interdisciplinary, bringing together skills in epidemiology, laboratory sciences, and biostatistics to identify the causes of cancer so that preventive measures may be adopted and the burden of disease and associated suffering reduced. A significant feature of the Agency is its expertise in coordinating research across countries and organizations; its independent role as an international organization facilitates this activity. IARC has a particular interest in conducting research in low- and middle-income countries through partnerships and collaborations with researchers in these regions. Registration not required.
