text: now that it has been proven that anti-perspirants cause cancer, what do we use??   there is no evidence that the sprays containing antiperspirant ingredients are the only ones with cancer causing properties.  this applies to any product (including sticks) that contains an antiperspirant ingredient (e.g. aluminum salts).  i would recommend using a deodorant only product, this suffices for most.  if you have severe underarm sweating, ask your physician about botox injections (they decrease sweating under the arms).
