Therefore, we carried out an umbrella review to systematically evaluate the validity and strength of the data and the extent of potential biases of the established association between adverse pregnancy outcomes and cancers risk in both mother and offspring.  \nMethods PubMed, Embase, and Web of Science databases were searched from inception until 18 January 2024. Meta-analyses of observational studies investigating the relationship between adverse pregnancy outcomes and multiple cancers risk in both mother and offspring were included. Evidence certainty was assessed using Grading of Recommendations, Assessment, Development, and Evaluation. The protocol for this umbrella review was prospectively registered in PROSPERO (CRD42023470544) .  \nResults The search identified 129 meta-analyses of observational studies and 42 types of cancer. Moderate certainty of evidence, exhibiting statistical significance, has been observed linking per kilogram increase in birth weight to a heightened risk of breast cancer (OR = 1 . 07, 95% CI = 1 .02–1. 12), prostate cancer (OR = 1 . 02, 95% CI = 1 .00–1. 05), leukemia (OR = 1 . 18, 95% CI = 1 .13–1. 23), and acute lymphoblastic leukemia in offspring (OR = 1 . 18, 95% CI = 1.12– 1. 23); rubella infection during pregnancy to an increased risk of leukemia in offspring (OR = 2 . 79, 95% CI = 1 .16–6. 71); and a linear dose–response association between an increase in the proportion of optimal birth weight and an elevated risk of acute lymphoblastic leukemia in offspring (OR = 1 . 16, 95% CI = 1 .09–1. 24), respectively.  \n†Na Liu, Rui-Han Bao, Yu-Jiao Chang and Fang-Hua Liu contributed equally to this work.  \n*Correspondence:  \nYue-Yang Zhao [zhaoyy@sj-hospital.org](zhaoyy@sj-hospital.org)[ ](zhaoyy@sj-hospital.org)Jian-Hua Fu [fujh@sj-hospital.org](fujh@sj-hospital.org)[ ](fujh@sj-hospital.org)Qi-Jun Wu [wuqj@sj-hospital.org](wuqj@sj-hospital.org)[ ](wuqj@sj-hospital.org)Ting-Ting Gong [gongtt@sj-hospital.org](gongtt@sj-hospital.org)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2024.
