In the 1990s, a chain email circulated around the series-of-tubes we called the internet, suggesting that aluminum-containing antiperspirants clogged your sweat pores, thus disallowing your body to “purge itself of toxins”, and those "toxins" would accumulate in your axillary lymph nodes, and increase your risk of breast cancer. Yikes.

Predating the "antiperspirant-will-give-you-breast-cancer" chain email scare, animal studies in the 1960s suggested a link between aluminum in antiperspirants (which were just becoming popular in postwar America) and Alzheimer's disease. These rabbit studies showed brain neurotoxic effects when the animals were exposed to very high levels of aluminum.

In the past several decades, researchers have investigated whether these loose correlations/hypotheses held any water (spoiler: they don't). In today's episode, Your Doctor Friends want to debunk and demystify the data around the potential "risks' around aluminum-containing antiperspirants!

Should you ditch the standard roll-on? Switch to a "natural" alternative?

OR.. is this all just a case of "all stink and no fire"??

AND FINALLY- a 2017 article from The World Textile Conference called "A novel washing algorithm for underarm stain removal" - which was the closest thing to scientific data explaining WHAT MAKES YELLOW ARMPIT STAINS!
