Cancer is the second leading cause of death globally. Death rates from cancer reflect global inequality; approximately 70% of deaths from cancers occur in low- and middle-income countries (LMICs). Due to high costs of cancer treatment and limited access to resources, these countries are unable to use treatment as a primary means for reducing cancer burden. Thus, redirecting focus from treatment to prevention in LMICs and considering prevention as a global public health imperative are critical. The AMA and policies can guide efforts to promote and support cancer prevention in LMICs.
癌症是全球第二大死亡原因。癌症死亡率反映了全球不平等现象；大约 70%的癌症死亡发生在低收入和中等收入国家（LMICs）。由于癌症治疗费用高昂，资源有限，这些国家无法将治疗作为减轻癌症负担的主要手段。因此，将重点从中低收入国家的治疗转向预防，并将预防视为全球公共卫生的当务之急至关重要。AMA 和政策可以指导促进和支持中低收入国家癌症预防的努力。
