In April 2024, the World Health Organization/International Agency for Research on Cancer (IARC) published the global cancer statistics 2022 in the CA: Cancer Journal for Clinicians. This report focuses on the incidence and mortality of 36 cancers in 185 countries or territories worldwide, analyzing the differences of gender, geographic region, and the Human Development Index (HDI) level. It is estimated that in the year 2022, there were 19.96 million new cancer cases and 9.74 million cancer deaths worldwide. Lung cancer (2 480 301, 12.4%) was the most frequently diagnosed cancer in 2022, followed by female breast cancer (2 295 686, 11.5%), colorectal cancer (1 926 118, 9.6%), prostate cancer (1 466 680, 7.3%), and gastric cancer (968 350, 4.9%). Lung cancer (1 817 172, 18.7%) was also the leading cause of cancer death, followed by colorectal cancer (903 859, 9.3%), liver cancer (757 948, 7.8%), female breast cancer (665 684, 6.9%), and gastric cancer (659 853, 6.8%). With demographics-based predictions indicating that the number of new cases of cancer will reach over 35 million by 2050. The Beijing Office for Cancer Prevention and Control team has collated this report and briefly interpreted it in combination with the current situation of cancer incidence and mortality in China.
2024年4月，世界卫生组织国际癌症研究机构团队在CA： A Cancer Journal for Clinicians杂志发表了2022年全球恶性肿瘤统计报告，重点阐述了世界185个国家或地区36种恶性肿瘤的发病和死亡情况，并分析不同性别、地理区域和以人类发展指数划分的不同经济区域的差异。据估计，2022年全球新增1 996.5万恶性肿瘤新发病例和973.7万死亡病例。全球发病前5位的癌种分别为肺癌（248.0万，12.4%）、女性乳腺癌（229.6万，11.5%）、结直肠癌（192.6万，9.6%）、前列腺癌（146.7万，7.3%）和胃癌（96.8万，4.9%）。死亡前5位的癌种分别为肺癌（181.7万，18.7%）、结直肠癌（90.4万，9.3%）、肝癌（75.8万，7.8%）、女性乳腺癌（66.6万，6.9%）和胃癌（66.0万，6.8%）。基于当前人口特征估计，至2050年全球恶性肿瘤新发病例将超过3 500万。北京市肿瘤防治研究办公室团队对该报告进行了整理，并结合中国恶性肿瘤发病和死亡现况进行简要解读。.
