Debunking Aluminum Myths - Part 2: Breast Cancer
In this second post of a three-part series, I review the "controversy" around aluminum and breast cancer
Background
The theoretical connection between breast cancer and antiperspirants is that aluminum compounds may be absorbed by the skin and into the breast tissue. Further, most breast cancers develop in the upper and outer portion of the breast, which is near where antiperspirants are applied to the underarms.
In reality: (1) it is unclear how much aluminum is absorbed through the skin when using antiperspirants; and (2) breast cancer tissue does not appear to contain more aluminum than non-cancerous breast tissue.
While there have been small case-control studies showing a potential link, the American Cancer Society's stance on the matter is that: "most studies have not found a link between antiperspirant use and the development of breast cancer” and that the case-control studies suggesting a potential link “need to be interpreted with caution because of their small size.”
Bottom Line
The National Cancer Institute's researchers have concluded that they "are not aware of any conclusive evidence linking the use of underarm antiperspirants or deodorants and the subsequent development of breast cancer." Some individuals may decide to stop using antiperspirants out of an abundance of caution, but there is no disagreement on whether aluminum-containing antiperspirants stop sweat.
