Per your note, I looked in
a few health books that I have
and from that I've discovered
that there are two things that
you seem to be confusing. There
is something called "film screen
mammography," which describes
the actual process. This means
that the breasts are squeezed
more tightly between the plates
to ensure a better quality picture.
The other option is "xerography."
Separately, there is something
called "baseline mammogram,"
which is a mammogram taken when
a woman is 35 or 40 and is used
as a basis for camparison with
all future mammograms.
I hope this helps to answer
your question. You should also
check out the health
links here at FEMINIST.COM.
