Glyphosate as an Emerging Environmental Pollutant and Its Effects on Breast Cancer Cell Proliferation: A Systematic Literature Review of Preclinical Evidence.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The widespread use of glyphosate-based herbicides (GBHs) has raised concerns about their potential role in hormone-sensitive cancers such as breast cancer. This systematic review aimed to evaluate preclinical evidence on the effects of glyphosate (pure compound) or glyphosate-based herbicide formulations (GBHs) exposure on breast cancer cell proliferation and related molecular pathways. A structured search was conducted across PubMed, ScienceDirect, and Springer Nature Link, Web of Science databases, covering studies published up to 9 November 2025, following a PROSPERO-registered protocol (ID: CRD42021238350). Eligible studies included original in vitro and in vivo preclinical research using human breast cancer cell lines (e.g., MCF-7, T47D, MDA-MB-231, MCF-12A, and MCF-10A) or relevant animal models. Outcomes assessed included cell viability, proliferation, tumor growth, apoptosis, cell cycle regulation, and molecular markers associated with endocrine signaling. Two reviewers independently screened and extracted data, resolving disagreements via discussion or third-party adjudication. From an initial pool of 699 articles, seven in vitro studies met the inclusion and quality criteria. Glyphosate exposure demonstrated weak estrogenic activity in ER-positive breast cancer cells, primarily via ERα modulation and altered gene expression related to proliferation and DNA repair. GBHs showed greater cytotoxic and epigenetic effects in non-tumorigenic cells, often independent of ER signaling. No included study employed in vivo breast cancer models. Overall, preclinical evidence suggests glyphosate may act as a weak endocrine disruptor under specific conditions, but findings are limited by the short-term in vitro designs, heterogeneous methodologies, and lack of chronic or in vivo data. Further research using long-term exposure and animal models is needed to clarify potential risks and inform regulatory and public health decisions.
