Talc powder exposure linked to mesothelioma

MANHASSET, N.Y., Oct. 17, 2019 /PRNewswire/ -- For the first time, Jacqueline Moline, MD, MSc, professor in the Institute of Health Innovations and Outcomes Research at The Feinstein Institutes for Medical Research, and her colleagues have identified household talcum powder contaminated with asbestos as the root cause of malignant mesothelioma in 33 long-term users, as published in the Journal of Occupational and Environmental Medicine.

Dr. Moline, who is also professor of Occupational Medicine, Epidemiology and Prevention at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, reviewed data, medical records, and sworn testimony of individuals with malignant mesothelioma, who were all exposed to consumer talcum powder products. The research published includes six case studies detailing decade-long use of talc powder, often starting from childhood, along with tissue digestion samples. The patients had no other known exposure to asbestos, and in the six detailed, the tissue analysis revealed the presence of asbestos commonly found in talc and not that found in other commercial products, such as automobile brakes or home insulation materials. It was determined that the 27 other individuals in the study were also linked to contaminated talcum powder, as they had no additional exposure to asbestos.

"The history of mesothelioma and workplace asbestos exposure has been well documented, but never has there been an investigation of the users of household talcum powder and malignant mesothelioma," said Dr. Moline, a nationally-recognized expert in World Trade Center health effects, asbestos exposure, occupational lung disorders and heavy metal toxicity. "Cosmetic talc still remains unregulated and on store shelves. Our findings show that these products, often used every day, were contaminated with dangerous asbestos, which has led to deadly health effects."

Asbestos is silicate mineral fibers that, if breathed, can lead to long-term health problems, including malignant mesothelioma. Asbestos contamination of consumer talc, includes body powder, baby powder and facial cosmetics, occurs when talc is mined from areas in which talc deposits overlap with naturally occurring asbestos deposits. Manufacturers of household talc are not legally obligated to register cosmetic products with the US Food and Drug Administration (FDA) and are essentially unregulated on store shelves.

"Dr. Moline's leadership in occupational health research furthers our understanding of the dangers of asbestos exposure," said Kevin J. Tracey, MD, president and CEO of the Feinstein Institutes.

"This study shows that it is important to take a comprehensive exposure history when evaluating patients presenting with cancers like mesothelioma," added Dr. Moline.
