An they say aluminum can cause breast cancer in some.You bet it does......its a compound called aluminum chlorhydrate. Its made by reacting aluminum with hydrochloric acid. Actually they use aluminum hydroxide to prevent a potential explosion hazard during the manufacturing process. Aluminium-based complexes (chlorhydrates) react with the electrolytes in the sweat to form a gel plug in the duct of the sweat gland. The plugs prevent the gland from excreting liquid and are removed over time by the natural sloughing of the skin. The aluminum salts interact with the keratin fibrils in the sweat ducts and form a physical plug that prevents sweat from reaching the skin’s surface. Aluminum salts also have a slight astringent affect on the pores; causing them to contract, further preventing sweat from reaching the surface of the skin. The blockage of a large number of sweat glands reduces the amount of sweat produced in the underarms, though this may vary from person to person. Aluminum is considered a heavy metal and has been shown (in its elemental form only) to alter the physiology of the blood-brain barrier. Antiperspirants are considered drugs by the FDA and no test yet performed shows a link between Aluminum chlorhydrate and breast cancer, brain cancer or any other cancer for that matter. Hey, you asked......actually, it\'s usually ANTI-PERSPIRANTS that contain aluminum. what the aluminum does, is block the sweat from exiting your sweat glands, therefore, keeping your underarms dry. however, your body sweats for a couple reasons: one being the method to rid toxins. when you block the main glands, which just so happen to be under your arms, you risk keeping those toxins in your body. Now, deodorant on the other hand, allows you to naturally perspire, but just adds an aroma if you will so that you won\'t smell funky. it won\'t keep you as dry, though. i would love to be able to use plain deodorant or the organic kind you mentioned, but i sweat a lot must resort to using anti-perspirants. if you must, just keep it to a minimum. for example, don\'t use at night. let your body cleanse itself while you sleep at leastLa okorder.com/i didnt know that, but try looking at the back of the deodorant cans/bottlesNo, that\'s crap. If that were true, any somewhat clean person who wears deodorant would have breast cancer. So, no.Other related question
