Talc powder is widely used for different purposes worldwide. Effects of talc on the human health is a concern as it has many chemical components. This review is an attempt to present the relevant researches in this field and to summarize the current updates about the topic. Talcum powder exposure has been shown to be a reason in the development of mesotheliomas and carcinoma of the lung in women. Regular cosmetic powders can get attached to larger particles that would deposit in the upper airways of the human respiratory system. The alveolar region is the second most exposed region of the respiratory system. Deposition levels in the tracheobronchial region is the lowest. Cosmetic talc powder, used regularly by women worldwide, can cause detrimental effects on different organ systems of the human body.
