J Clin Oncl
This large-scale Danish nationwide study followed 1.12 million women over nearly 10 million woman-years to examine the relationship between phthalate exposure from prescription medications and breast cancer risk. The researchers tracked phthalate exposure by linking a database of drug ingredients with prescription records, finding that most phthalate exposures were not associated with increased breast cancer risk. However, high-level cumulative exposure to dibutyl phthalate (≥10,000 mg) was associated with approximately double the risk of estrogen receptor-positive breast cancer, consistent with laboratory evidence showing this compound has estrogenic effects. The study concludes that women should avoid high-level dibutyl phthalate exposure, particularly through long-term use of pharmaceuticals containing this compound, though lower exposure levels did not increase breast cancer risk.

Endocrine Disrupting Chemicals (EDCs)—including bisphenol A, phthalates, parabens, pesticides, and heavy metals commonly found in pharmaceuticals, cosmetics, and packaging—are widespread environmental pollutants that interfere with the body’s hormone system. Research shows EDCs have harmful effects on women’s reproductive health, contributing to conditions such as endometriosis, polycystic ovary syndrome, uterine fibroids, premature ovarian failure, menstrual irregularities, and infertility. This review emphasizes the need for healthcare professionals to consider environmental exposures when evaluating patients, highlights potential mechanisms by which EDCs affect female reproduction, and discusses how nutritional interventions and stricter environmental regulations could help reduce EDC-related health risks. Understanding the link between EDCs and women’s health is crucial for developing protective strategies, informing treatment approaches, and shaping public policies to safeguard reproductive and overall well-being. The study seeks to advise that couples attempting to conceive should avoid endocrine disrupting chemicals (EDCs) such as BPA, pesticides, and phthalates. Following this advice is found to be crucial during the prenatal and periconceptional periods, where fetal development and growth are critical in this window.

Biodegradable polymers are emerging as a promising solution for removing endocrine-disrupting chemicals (EDCs) from wastewater. EDC’s, found in pharmaceuticals, pesticides, and personal care products pose serious health risks, impacting the endocrine system and disrupting reproductive health. Traditional water treatments often fail to fully remove EDCs. Biodegradable polymers, with strong adsorptive properties, offer a sustainable and effective method, helping to minimize EDC exposure and protect human and environmental health.

A review examining parabens—one of the most widely used preservatives worldwide in foods, cosmetics, and pharmaceuticals—found that these easily absorbed chemicals are classified as endocrine-disrupting chemicals (EDCs) that can disrupt hormonal homeostasis and cause multidirectional health implications affecting body fitness and function. The review summarizes current literature on paraben properties, occurrence, metabolism, and particularly their influence on the human endocrine system, emphasizing the importance of assessing their safety given their ubiquitous use and absorption. With parabens now recognized as EDCs capable of disrupting endocrine function, the authors highlight concerns about widespread population exposure through everyday consumer products and the need for precise assessment of their health impacts on human physiology.

The following review article described how exposure to EDCs during early development can lead to adverse health outcomes later in life through epigenetic mechanisms based on existing studies. The article emphasizes that exposure to EDCs during critical developmental periods such as in utero and early childhood, can have lasting effects on health since, during these periods, the body’s systems are particularly vulnerable to exposures. Additionally, the article finds a link between early-life exposure to EDCs and increased risk of various health issues later on in life, including metabolic disorders and cancers. The suspected mechanism by which these chemicals do this is thought to be mediated by epigenetic changes, which are changes to gene expression without altering the DNA. Therefore, the article emphasizes understanding how exposure during such sensitive periods in development can pose such drastic problems later on in life.

Trifluoroacetic acid (TFA)—a persistent and mobile chemical produced when many PFAS, fluorinated gases, pesticides, and pharmaceuticals break down—is accumulating irreversibly in rain, soil, drinking water, human blood, and food at concentrations orders of magnitude higher than other PFAS. TFA exhibits reproductive and liver toxicity in mammals and bioaccumulates readily in plants, yet ecotoxicity data remain limited, particularly for terrestrial ecosystems. Due to its extreme persistence, ongoing emissions from multiple sources, and irreversibly increasing concentrations, TFA may represent a “planetary boundary threat”—a substance reaching global-scale exposure levels that could trigger irreversible disruptions to vital Earth systems. The authors call for binding regulatory actions to reduce emissions of TFA and the many precursor chemicals that transform into TFA in the environment.

A study analyzing 65 seafood samples (195 analyses including raw and cooked preparations) from 11 European countries for pharmaceuticals (PhACs) and endocrine-disrupting compounds (EDCs)—chemicals linked to reproductive system effects, metabolic disorders, breast cancer pathogenesis, and antimicrobial resistance—found that while pharmaceuticals were mostly undetectable, EDCs were quantified in the majority of samples, with cooking by steaming significantly increasing their levels 2- to 46-fold. Human exposure assessment focused on three prevalent EDCs (bisphenol A, methylparaben, and triclosan) revealed that the Spanish population had the highest exposure through seafood consumption among the 11 countries studied, though exposures remained below current toxicological reference values. These findings highlight that commercially available seafood in the European Union market contains detectable levels of endocrine-disrupting contaminants that concentrate during cooking, raising concerns about cumulative dietary exposure to these compounds through this widely consumed protein source, particularly in populations with high seafood consumption patterns.
