my understanding is the antiperspirant theory of cancer is scoffed at
by the
medical establishment.  as is the idea that blocked lymph or chi has
anything to do with cancer.

re not having to use antiperspirant: Body Odor

Most body odor is the result of bacterial breakdown of sweat.
Perspiration
itself is normally odorless. An easy way to reduce the amount of
bacteria
under the arms is to splash on rubbing alcohol. Most commercial
deodorant
products contain irritating or harmful ingredients, including aluminum
salts
and dyes. Avoid the antiperspirant varieties. You can find better
products
in health-food stores, such as those containing extracts of green tea,
which
is antibacterial. Beware of "natural crystals," which contain aluminum
even
if they say they don't.

Stimulant drugs, including coffee and tea, contribute to body odor by
increasing the activity of apocrine sweat glands, special glands in
hairy
parts of the body that produce strong-smelling, musky secretions. Try
eliminating caffeine if body odor continues to be a problem.
