In the last several years, meta-analyses of human epidemiological data have provided strong evidence for risk of alcohol-associated cancers at seven body sites. It is now well accepted that several cancers are associated with alcohol consumption, and that risk increases with dose. In publications of epidemiological studies, statements like, \"…the safest level of drinking is none\" (Lancet 2018; 392: 1015-1035) have been interpreted to mean that any level of alcoholic beverage consumption is harmful. An official of the World Health Organization-Europe declared that \"It doesn't matter how much you drink - the risk to the drinker's health starts from the first drop of any alcoholic beverage.\" Recently, \"one-drop\" statements like this have been echoed by news outlets and in social media posts. If such pronouncements are unfounded, potential outcomes are that they raise unnecessary fear and hysteria among the alcohol-consuming public and sow distrust of respected sources. This commentary addresses the likelihood that very small amounts (e.g. one drop) of alcohol increase cancer risk. Examples of results from meta-analyses of human epidemiological studies that link alcohol consumption with human cancers are presented, with a focus on dose-response relationships. Next, what animal and <i>in vitro</i> studies suggest about alcohol-associated cancer thresholds is discussed. Thirdly, alcohol contents in common foods and production of alcohol from intestinal fermentation are explored, and how exposures from these compare to one drop of an alcoholic beverage is addressed. Finally, comments are offered on the consequences of issuing unsupported claims of cancer risk from consuming alcoholic beverages in moderation, and perspectives are shared on the responsibilities of researchers, public health agencies and the lay press to issue pronouncements that are evidence-based.</p>","PeriodicalId":10869,"journal":{"name":"Critical Reviews in Toxicology","volume":" ","pages":"1-13"},"PeriodicalIF":5.6,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149126863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Across this literature, inhalation was illustrated to follow a concentration-dependent continuum of effects confined to the tissues of initial contact. Controlled human chamber studies reported no measurable pulmonary impairment below 0.3 ppm, the onset of mild ocular and nasal irritation at 0.3 to 0.5 ppm, and reversible sensory irritation observed at concentrations approaching 1 ppm. These findings were consistent with observations from community and occupational investigations. Chronic inhalation bioassays in rats and mice identified a sharp transition between adaptive epithelial responses and sustained cytotoxic injury within the nasal epithelium. Continuous exposure to concentrations ≤2 ppm produced minimal and reversible histopathologic changes, whereas exposures ≥6 ppm were associated with persistent epithelial necrosis, regenerative proliferation, and nasal squamous cell carcinomas localized to regions of highest vapor flux in the rat nasal cavity. In these studies, tumors were not observed at concentrations that did not overwhelm local tissue repair capacity. Computational dosimetry, DNA-protein crosslink kinetics, and biologically based dose-response (BBDR) modeling indicated that these outcomes arose from localized tissue injury rather than from cumulative systemic dose. Despite the extensive experimental database, disagreement has persisted for several decades regarding the appropriate approach for conducting a quantitative risk assessment of formaldehyde. Its non-linear, concentration-response, high endogenous background levels, and pronounced interspecies differences would indicate that the use of the Linear-No-Threshold (LNT) model is not appropriate for identifying acceptable levels of exposure. Nonetheless, EPA proposed an 8-hour occupational exposure value (OEV) of 0.11 ppm and 0.17 ppm for a 15-minute OEV. This review synthesizes the human, experimental, and mechanistic evidence underlying formaldehyde's acute and chronic inhalation toxicity. Using a classic approach to risk assessment, we propose that an OEV of 0.3 ppm (8 hr TWA) and a short-term limit (15 min) of 1.0 ppm are sufficiently low to protect the vast majority of workers from temporary irritation, as well as chronic effects (such as cancer).

The current study further sought to characterize variability and its sources in follicle and CL counts. A database of 73 EOGRT studies with information on methodology, reporting and numerical data of follicular and CL counts was assembled and analyzed, revealing that quantitative follicle enumeration was conducted in 97% of studies, while quantitative CL evaluation was performed in 59%. Only 27% of studies provided details on sampling procedures related to location within the ovary, section thickness, step length, number of steps as well as type of histological staining. The percentage coefficient of variation (%CV) for follicle counts in control females ranged from 7.7% to 78.5%, indicating high variability. The median study-specific %CVs for primordial follicles and for combined primordial and growing follicles were 36% and 33%, respectively, while the median %CV for CL was 29%. The intra‑laboratory %CV decreased, indicating improved precision of the follicle‑count method, when a greater number of sections were evaluated but was also influenced by the number of studies performed within the laboratory, based on the dataset included in this evaluation. While the ratios of primordial to growing follicles are not a requirement in the OECD TG 443, they can reveal differences in follicle identification if the variability in ratios between the studies is high. Accordingly, the high variability in the ratios across studies demonstrated that well-defined criteria for follicle identification and validation of antibodies are necessary. The overall conclusion is that the lack of information on follicle identification criteria, and inconsistencies in terminology and reporting practices further complicate the interpretation of results of follicle and CL counts in the EOGRT studies.
