Trichloroethylene (TCE) has in the last few years been reclassified
as a class 2 carcinogen, which means that various exposure-reducing
precautions must be taken when it is used. TCE has not been banned
from industrial use, but at least in the US it may no longer be sold
to the general public. The major exposure-causing use is in the
vapor degreasing of metals, a process using many gallons of solvent
in an open-top boiler-condenser rig. There are millions of such
rigs, but liver cancer isn't all that common, even among workers
exposed daily. Despite all the hysteria now surrounding the subject
None of the common solvents, even those now known to be carcinogens,
are dangerous enough to be a problem for incidental users.
Something else will kill us first.

How do you know this? Are you a health professional? I have known as
many people to die from liver cancer as any other kind. Of course
there are many known causes of liver cancer such as alcoholism and
hepatitis infections.
