The Doctors welcome surgical breast specialist Dr. Kristi Funk to weigh in on the viewer question, "Does deodorant cause breast cancer?"
"This is false. It does not cause breast cancer," she says. She notes that in theory, the aluminum salts in antiperspirant deodorants can plug your pores, but she says this question has been studied extensively and no connection has been discovered.
"No scientific evidence links these products, deodorants and antiperspirants, to frankly any cancer," she continues. "There's nothing there."
When it comes to breast cancer, Dr. Funk says that what matters more when elevating your risk is drinking alcohol, eating processed meats, eating saturated fats, being overweight, hormone replacement therapy, and not exercising enough.
"Forget the deodorant, control those things," she says.
More breast myths and information about the breast can be found in Dr. Funk's book, "Breasts: The Owner's Manual."
