Global Cancer Statistics 2020: GLOBOCAN Estimates of Incidence and Mortality Worldwide for 36 Cancers in 185 Countries.

Worldwide, an estimated 19.3 million new cancer cases (18.1 million excluding nonmelanoma skin cancer) and almost 10.0 million cancer deaths (9.9 million excluding nonmelanoma skin cancer) occurred in 2020.

2020年，全球估计新发癌症病例1920万例（1810万例不包括非黑色素瘤皮肤癌），癌症死亡病例近1000万例（990万例不包括非黑色素瘤皮肤癌）。

Female breast cancer has surpassed lung cancer as the most commonly diagnosed cancer, with an estimated 2.3 million new cases (11.7%), followed by lung (11.4%), colorectal (10.0 %), prostate (7.3%), and stomach (5.6%) cancers.

乳腺癌已超过肺癌成为最常诊断的癌症，预计新发病例230万例（11.7%），其次为肺癌（11.4%）、结直肠癌（10.0%）、前列腺癌（7.3%）和胃癌（5.6%）。

Lung cancer remained the leading cause of cancer death, with an estimated 1.8 million deaths (18%), followed by colorectal (9.4%), liver (8.3%), stomach (7.7%), and female breast (6.9%) cancers.

肺癌仍是癌症死亡的首要原因，预计死亡180万例（18%），其次为结直肠癌（9.4%）、肝癌（8.3%）、胃癌（7.7%）和乳腺癌（6.9%）。

Overall incidencewas from 2-fold to 3-fold higher in transitioned versus transitioning countries for both sexes, whereas mortality varied <2-fold for men and little for women.

两性发病率在已转型国家均比转型中国家高2至3倍，而死亡率差异方面，男性小于2倍，女性几乎无差异。

Death rates for female breast and cervical cancers, however, were considerably higher in transitioning versus transitioned countries (15.0 vs 12.8 per 100,000 and 12.4 vs 5.2 per 100,000, respectively).

然而，女性乳腺癌和宫颈癌的死亡率在转型中国家明显高于已转型国家（分别为15.0比12.8/10万和12.4比5.2/10万）。

The global cancer burden is expected to be 28.4 million cases in 2040, a 47% rise from 2020, with a larger increase in transitioning (64% to 95%) versus transitioned (32% to 56%) countries due to demographic changes, although this may be further exacerbated by increasing risk factors associated with globalization and a growing economy.

预计全球癌症负担将在2040年达到2840万例，较2020年增长47%，其中转型中国家（64%至95%）的增幅高于已转型国家（32%至56%），主要归因于人口结构变化；此外，全球化及经济增长带来的风险因素增加可能进一步加剧这一趋势。

Efforts to build a sustainable infrastructure for the dissemination of cancer prevention measures and provision of cancer care in transitioning countries is critical for global cancer control.

在转型中国家建立可持续的基础设施以推广癌症预防措施和提供癌症诊疗服务，对全球癌症控制至关重要。
