Pesticide Exposure and Gynecological Cancers: A Review of Epidemiological Evidence and Mechanistic Pathways

Abstract

Environmental exposure to pesticides is considered a risk factor for gynecological cancers, contributing to their onset and progression through various mechanisms. This narrative review investigates the role of different pesticides in the development and progression of ovarian, endometrial, and cervical cancers, and provides a comprehensive synthesis of epidemiological findings along with molecular mechanisms, highlighting carcinogenic pathways, conflicting findings, and potential therapeutic implications. Relevant epidemiological and experimental studies published between 2000 and 2025 were identified through searches of major scientific databases. Various pesticides, particularly organochlorines, contribute to gynecological cancers through mechanisms such as estrogen mimicry, DNA damage, oxidative stress, increased pro-inflammatory cytokines, and disruption of cellular signaling pathways. However, most studies found no significant association between certain pesticides, such as Triazines and Atrazine, and gynecological cancers. Furthermore, some pesticides, like Carbendazim, exhibit a dual role; while carcinogenic, they can also serve therapeutic purposes in cancer treatment when utilized with nanotechnology. Overall, pesticide exposure is a significant factor in the development and progression of women’s cancers, although the strength of the evidence varies across pesticide classes. Despite numerous studies, contradictory findings necessitate further research to clarify causal relationships.
