Deodorant and Breast CancerExperiments made by Swiss researchers on mices show that deodorants containing aluminum salts caused tumors. In a study published in the International Journal of Cancer, Oncologist Professor André-Pascal Sappino and Dr. Stefano Mandriota believe that the "indictment against deodorants containing aluminum suspected to be carcinogenic" is significant. They advise consumers to apply the precautionary principle ... Professor Sappino is challenged in the role of aluminum in the surge of breast cancer, and challenged by the rise of breast cancers in very young women and Their location.80% of breast cancers appear right next to the trough of the armpit, upper outer quadrant of the breast, nearest to where antiperspirants are applied. That is to say the place where the epidermis is extremely permeable and where the lymphatic system that drains the mammary gland is...Several studies have revealed the presence of aluminum in the breast tissue ... weak, but has nothing to do there!In 2012, the oncologist published a first study with biologist Stefano Mandriota. It establishes that, in contact in vitro with normal human mammary cells, "aluminum, to our surprise, within a few weeks, disrupts their behavior and makes them take the characteristics of malignant cells": unable to stop multiplying . "This study provoked a certain skepticism, on the grounds that it was limited to an in vitro model," the doctor acknowledged. Two years later, the Brussels Commission considered that the risks were impossible to evaluate. Mammary cells of mices are used, in vitro always, with aluminum salts."Rates 1,000 to 100,000 times lower than those in a deodorant," they say. After a few months, they were injected to different groups of healthy mices, but with a more or less valiant immune system. Result: "In all, we have seen the development of tumors to varying degrees, but sometimes very aggressive, forming metastases. "Aluminum antiperspirants can be a source of long-term exposure to aluminum, it means that women can accumulate large doses in the breast tissue. Among other things, aluminum can cause DNA damage as well as epigenetic effects (changes) that can promote the development of cancer. Aluminum (especially aluminum chloride and aluminum hydrochloride) is also known to interfere with estrogen receptors in breast cancer cells, and estrogen plays a well-known role in breast cancer.In 2005 researchers faced with these results have legitimately raised the possibility of a link with the long-term dermal absorption in this area in the increasing incidence of breast cancer.
"Given the wide exposure of the human population to antiperspirants, it will be important to establish dermal absorption in the local area of the breast and whether long term low level absorption could play a role in the increasing incidence of breast cancer."In 2013, researchers found increased levels of aluminum in nipple aspirate fluid from women with breast cancer compared to women without the disease. They also detected increased levels of inflammation and oxidative stress.
" … [O]ur results support the possible involvement of aluminum ions in oxidative and inflammatory status perturbations of breast cancer microenvironment, suggesting aluminum accumulation in breast microenvironment as a possible risk factor for oxidative/inflammatory phenotype of breast cells."
The ParabensParabens in deodorants can also be linked to breast cancer.Parabens are preservatives that are found in many antiperspirants and deodorants. These chemicals have estrogenic activity in breast cancer cells, and research published in 2012 found one or more parabens in 99% of the 160 tissue samples taken from 40 mastectomies. A separate search also detected parabens in 18 of the 20 tissue samples from breast tumors. Although a definitive link has not been made, the increasing collection of research invites us to be very cautious.
As of 2011, the French Agency for the Safety of Health Products (Afssaps), now the National Agency for the Safety of Medicines and Health Products (ANSM), recommends that they should not be used on damaged skin and 0.6% concentration in antiperspirants. A rate that is not mentioned on the products. How many of us when shaving our armpits did cut? Can hot waxing be considered as "damaging"? ...
