Cancer burden in low-income and middle-income countries

In this Viewpoint, we asked experts to discuss this burden and what is needed to alleviate it. In this Viewpoint, we asked four experts to discuss the increasing burden of cancer in low- and middle-income countries; they explore the changes that are necessary to improve cancer diagnosis, prevention and treatment within these nations.
