Global Cancer Burden and Natural Disasters: A Focus on Asia’s Vulnerability, Resilience Building, and Impact on Cancer Care

Abstract

The world has been witnessing more frequent and greater intensity weather-related disasters. Natural disasters hit every continent in the world. Asia has borne the brunt in terms of frequency and the total numbers of people affected. This is mainly because of Asia’s increasing population and its large and varied landmass, with multiple river basins, mountains, flood plains, and active seismic and volcanic zones. The Union for International Cancer Control New Global Cancer Date: GLOBOCAN 2018 has estimated the global cancer burden to have risen to 18.1 million new cases and 9.6 million deaths. Asia constitutes roughly 60% of the world’s population. The region contributes nearly one half of new cancer cases and more than one half of cancer deaths worldwide. This increase in the regional burden of cancer is largely a result of socioeconomic growth and the increasing size and aging of the population. In addition to the increasing cancer cases, the string of natural disasters will cause heavy damage and a great human toll in Asia. Medical care for disaster-affected populations is focused traditionally on the management of immediate trauma and acute infections. For people with noncommunicable diseases, this presents a significant risk. Patients with cancer are especially susceptible to the disruptions that natural disasters can cause. Their special needs are largely neglected. There is a need to refocus and expand disaster risk reduction strategies and resources to include patients with noncommunicable diseases such as cancer, because these conditions are generating the bulk of disability, ill health, and premature death around the globe. Having the world’s biggest burden of cancer, Asia will definitely be facing these challenges.
