The WHO classifies talc as “probably” carcinogenic

Him baby powder recently classified as “probably carcinogenic” by the Agency for Research on Cancer of the World Health Organization (OMS), a report that also includes acrylonitrile, an organic compound that is mainly used in textiles and plastics.

Although the evidence in humans is limitedby other studies confirm that there are potential risks in the use of talc – a natural mineral used in the cosmetics, food and pharmaceutical industry – due to the consequences associated with crab egg.

Through a statement, the agency trusted by the United Nations explained that the discovery occurred from International Cancer Research Institute (CIRC/IARC), a working group of 29 international experts convened in Lyon (France), and was published after a comprehensive review of the scientific literature.

The authorities don’t like this

Professional and critical journalism is a fundamental pillar of democracy. That is the reason why he always annoys those who believe that they are the true riches.

Talc is a natural mineral that is essentially magnesium silicate.

WHO declared talc “probably” carcinogenic

“The working party distributed talc like probably carcinogenic for humans (Group 2A) based on a combination of limited evidence for cancer in humans (for ovarian cancer), enough evidence for cancer in experimental animals and strong mechanistic evidence that the talc exposure characteristics clave dand carcinogens inside human stem cells and testing methods”, indicates the WHO, explaining that the indicated group refers to the second highest level of certainty that a component can cause cancer.

The discovery was previously published in the journal Lancet Oncology, describe this classification based on studies that suggest a group between minerals y ovarian cancer in humans, as well as sufficient evidence obtained from studies with laboratory animals.

Although primary exposure occurs in industrial settings during mineral extraction, milling, or processing, exposure also occurs through the use of cosmetics y body powders containing talc, which ends up affecting everyone.

“However, experts point to possible inconsistencies in the studies that indicate it increase in cancer incidence“added researchers from the WHO-based institute. Although the evaluation focused on talc-free abusewe know that in many studies done with people there can be dirt including minerals.

Recently, the pharmaceutical giant Johnson & Johnson deal with justice in 42 states in the United States in relation to allegations that its talc products may have caused cancer.

However, a compilation of studies published in January 2020, based on a large sample of 250,000 women in the United States, did not find a statistical link between the use of talcum powder on the genitals and the risk of ovarian cancer.

Concerns about the asbestos contamination of talc arose in the 1970s, since asbestos was often found in the vicinity of talc deposits. Later research showed an increased risk of ovarian cancer among talc users.

Talc is used in many products, such as cosmetics, body powders, medicines, and in the food industry as an anti-caking agent.

WHO also declares acrylonitrile as carcinogenic.

In addition to talc, the WHO also declares talc “carcinogenic” to humans. acrylonitrile, a volatile organic compound used in the production of polymers for textiles and plastics. In this case the IARC classified it within Group 1, that is, the highest level of certainty that a substance can cause cancer in humans.

This classification is based on “enough evidence.” lung cancer“and “limited evidence” of crab bladder in humans, due to exposure that can arise both in the industrial production of polymers and in cigarette smoke and air pollution.

The strongest evidence, meanwhile, “comes from a large group study of workers from different industries that produce or use acrylonitrile. In this study, the workers with the highest exposure to acrylonitrile were the higher the rate for lung cancer compared to workers with less exposure.

This volatile organic compound is primarily used in the production of polymers used in fibers for clothing, carpets, plastics for consumer products, and automotive components. In addition, acrylonitrile is present in cigarette smoke, and air pollution represents another important source of exposure, raising concerns about human exposure to this dangerous substance.
