Antiperspirant Linked to Breast Cancer?
The researchers found higher concentrations of the parabens in the upper outer quadrants of the breast and axillary area, which is where antiperspirants are usually applied. Researchers did, however, comment on a significant issue; “The source of the paraben cannot be identified, but paraben was measured in seven of 40 patients who reported never having used underarm cosmetics in their lifetime.” There was no correlation found between paraben concentrations and age, tumour location, tumour oestrogen receptor content or length of breastfeeding. The editorial review of study noted that; “The data from this latest study, the most extensive examination of parabens in human breast so far published, confirm previous work and raise a number of questions on the entire parabens, personal-care product and human health debate, particularly relating to the source and toxicological significance of the paraben esters.” There does, however, need to be more research completed before antiperspirants can be deemed a carcinogen. In 2009, researchers at the United States National Cancer Institute (NCI), part of the National Institutes of Health, studied underarm antiperspirants and deodorants and claimed that they are “not aware of any conclusive evidence linking the use of underarm antiperspirants or deodorants and the subsequent development of breast cancer.” The NCI also commented, saying that “the US Food and Drug Administration, which regulates food, cosmetics, medicines and medical devices, also does not have any evidence or research data that ingredients in underarm antiperspirants or deodorants cause cancer.”
