After having six lymph nodes removed from my armpit during my mastectomy, I am careful about the products I apply to my skin at the suture sites. Thankfully, chemotherapy killed all the bacteria in my body, so I've been able to go all through summer with odorless perspiration! That's begun to change, so I've started my research on the correlation of deodorant and breast cancer.
According to The National Cancer Institute, aluminum-based compounds are used as the active ingredient in antiperspirants; they form a temporary plug within the sweat duct that stops the flow of sweat to the skin's surface. These compounds, applied frequently and left on the skin near the breast, are absorbed by the skin and cause estrogen-like effects, promoting the growth of breast cancer cells. Parabens, preservatives also used in some deodorants and antiperspirants have been shown to mimic the activity of estrogen in the body’s cells as well. Parabens can be identified on ingredient labels as methylparaben, propylparaben, butylparaben, or benzylparaben. "However, researchers at the National Cancer Institute, a part of the National Institutes of Health, are not aware of any conclusive evidence linking the use of underarm antiperspirants or deodorants and the subsequent development of breast cancer."
The suggestion that aluminum-based compounds and parabens may cause cancer is enough for me to choose products that eliminate their use on my sensitive skin; I don't want to apply carcinogenic products on an area where my lymph nodes have removed, leaving my body susceptible to absorbing harmful chemicals in an area that especially lacks the defense mechanism to filter what goes into my blood stream. Therefore, I chose EO Certified Organic Lavender Organic Spray, void of harsh irritants, aluminum and parabens, still killing bacteria and replacing odor with the soothing smell of lavender.
