Talkpoeder en kanker


Bijna iedereen gebruikt Talkpoeder, vaak bevat Talkpoeder, Asbest en diverse Chemicalien, die bij intensief gebruik, oa, huid irritatie kunnen veroorzaken. Diverse ziekenhuizen hebben nu de Chemisch samen gestelde Talkpoeder vervangen voor Natuurlijk samengestelde Talkpoeder. In het dagelijkse leven proberen we te ontkomen aan milieuziektes, en zo weinig mogelijk chemische produkten te gebruiken. Diverse chemische stoffen kunnen " celveranderingen "in de organen veroorzaken. Bestudeer altijd het etiket voordat je iets koopt.

Why is talc harmful?

A. Talc is closely related to the potent carcinogen asbestos. Talc particles have been shown to cause tumors in the ovaries and lungs of cancer victims. For the last 30 years, scientists have closely scrutinized talc particles and found dangerous similarities to asbestos. Responding to this evidence in 1973, the FDA drafted a resolution that would limit the amount of asbestos-like fibers in cosmetic grade talc. However, no ruling has ever been made and today, cosmetic grade talc remains non-regulated by the federal government. This inaction ignores a 1993 National Toxicology Program report which found that cosmetic grade talc, without any asbestos-like fibers, caused tumors in animal subjects.1 Clearly with or without asbestos-like fibers, cosmetic grade talcum powder is a carcinogen.

Safety

Several studies have established preliminary links between talc and pulmonary issues,[1] lung cancer,[2][3] skin cancer and ovarian cancer.[4] This is a major concern considering talc's widespread commercial and household use. However, no conclusive study has yet been made to determine either the toxicity and/or carcinogenic nature of talc and the long history of safe use suggests that these concerns are unfounded. The U.S. Food and Drug Administration (FDA) considers non-asbestiform talc, that is talc which does not contain potentially carcinogenic asbestiform amphibole fibers, to be Generally recognized as safe (GRAS) for use in cosmetics. In 1993, a US National Toxicology Program report found that cosmetic grade talc caused tumours in animals, even though it contained no asbestos-like fibres. Scientists have been aware of the toxicity of talc since the late 1960s, and in 1971 researchers found particles of talc embedded in 75 percent of the ovarian tumors studied

Baby and talc powder

So, clearly talc can cause pneumonia, inflammation (or swelling) of the airways of babies, and even death. But what about cancer? When the link to asbestos and cancer came to light, it was noticed that a lot of the exposure to asbestos was accompanied by other inhalable fibers and dust including talc.

Symptoms

Most symptoms are caused by accidental or repeated breathing in (inhaling) of talc dust. Breathing problems are the most common problem.

Does Talc Cause Ovarian Cancer in Humans?

A case-control study published in 1997 of 313 women with ovarian cancer and 422 without this disease found that the women with cancer were more likely to have applied talcum powder to their external genital area or to have used genital deodorant sprays. Women using these products had a 50% to 90% higher risk of developing ovarian cancer.

Talcum powder 'poses cancer risk to women'

The practice of discreetly puffing underwear with a dab of talcum powder may be increasing women's risk of ovarian cancer.
