Book excerpt: Though cancer was once considered to be a problem primarily in wealthy nations, low- and middle-income countries now bear a majority share of the global cancer burden, and cancer often surpasses the burden of infectious diseases in these countries. Effective low-cost cancer control options are available for some malignancies, with the World Health Organization estimating that these interventions could facilitate the prevention of approximately one-third of cancer deaths worldwide. Effective cancer treatment approaches are also available and can reduce the morbidity and mortality due to cancer in low-resource areas. But these interventions remain inaccessible for many people in the world, especially those residing in low-resource communities that are characterized by a lack of fundsâ€"on an individual or a societal basisâ€"to cover health infrastructure and care costs. As a result, worse outcomes for patients with cancer are more common in low- and middle-income countries compared with high-income countries. Few guidelines and strategies for cancer control consider the appropriateness and feasibility of interventions in low-resource settings, and this may undermine the effectiveness of care. Recognizing the challenges of providing cancer care in resource constrained settings, the National Academies of Sciences, Engineering, and Medicine developed a two- workshop series examining cancer care in low-resource communities, building on prior work of the National Academies. The first workshop, held in October 2015, focused on cancer prevention and early detection. The second workshop was held in November 2016, and focused on cancer treatment, palliative care, and survivorship care in low-resource areas. This publication summarizes the presentations and discussions of this workshop.
