Talc has many uses in cosmetics and other personal care Histologic evaluation of lung tissue revealed no exposure-related lesions except for a modest, diffuse increase in free macrophages within alveolar spaces of both rats and mice exposed to the highest concentration of talc. 13. In its most recent review of talc, the International Agency for Research on Cancer (IARC) concluded [t]here is inadequate evidence in humans for the carcinogenicity of inhaled talc (4). (2020) 63:4849. (42) were employed <1 year (42). A few studies reported excess lung cancer mortality, but lung cancer mortality risk did not increase with increasing talc exposure and the association potentially was confounded by smoking.

A three-fold excess of mortality due to NMRD was reported in the earliest cohort study of New York talc workers, reflecting the high concentrations of dust present in the workplace; prior to 1948, median exposures ranged from 61 to 1,196 mppcf (45). Of these, 19 epidemiology studies and three animal studies were determined to address pulmonary cancers and included in this systematic review. (2007) 29:75760.

When considered together, the moderate confidence in study findings, large study populations, long duration of follow up, and consistency of null findings indicate that talc exposure is not associated with mesothelioma. Please note that the item can still be purchased. This exposure assessment focuses on routes of exposure where critical effects have been identified, namely non-cancer lung effects following inhalation of insoluble respirable particles of talc, and an association with ovarian cancer following perineal exposure to talc.

Pickrell JA, Snipes MB, Benson JM, Hanson RL, Jones RK, Carpenter RL, et al. The objective of this paper was to apply systematic review methods to critically evaluate and synthesize the scientific evidence addressing the possible relationship(s) between exposure to talc occupationally and from exposure to talc-containing products (primarily talcum powders and cosmetics) and pulmonary cancers, specifically lung cancer and pleural mesothelioma, integrating epidemiology, toxicology, and studies informing potential underlying modes of action.

Therefore, the large amount of available animal and clinical data the Panel relied on in assessing the safety of talc only. Northern Italy: An updated cohort study. Relative to cohort members with the lowest cumulative respirable dust exposure (0 to <95.1 mg/m3), individuals in the two highest cumulative exposure groups had slightly reduced lung cancer risk (RR for cumulative exposure of 95.1-<987 mg/m3 = 0.8; 95% CI: 0.31.9, and RR for cumulative exposure of 987+ mg/m3 = 0.5; 95% CI: 0.21.3).
