Introducing a New Hypothesis in the Genesis of Breast Cancer: An Integrative Review.
Review in Breast cancer (Dove Medical Press), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Breast cancer is the second most common cancer among women worldwide. Estrogen is currently identified as one of the main agents involved in the initiation of breast tumors; however, evidence indicates a greater risk when estrogen replacement is combined with progesterone, whereas its isolated use does not represent a significant risk. Inconsistencies in existing theories highlight the need for further detailed research on the relationship between hormone exposure and breast tumorigenesis, with particular emphasis on fibrinogen and its components in the context of this review. Objective: Introduce a new theory into the medical literature concerning the genesis of breast cancer. Methods: This is an integrative literature review based on a selection of relevant articles published between 2000 and 2025, in both Portuguese and English, and sourced from the following databases: Scielo, ScienceDirect, National Library of Medicine, PubMed, Cochrane, Results: Fifty-six references were selected to support the development of the discussion components, which are subdivided into the following themes: physiology of estrogen and progesterone in the body, actions of hormonal therapies, both combined and isolated, in breast cancer, and fibrinolytic physiology. Conclusion: After identifying contradictions in current theories about the influence of estrogen on tumor proliferation, which encouraged the search for new interpretations, it was demonstrated that free estrogen and its by-products, such as fibrinogen-related protein (fibrinogen-like protein 1 and 2), play a role in the immune system's failure to contain malignant cells, opening another field of therapeutic research for breast cancer.
