The wide use of mammographic screening and breast conservation surgery
, as well as the introduction of a variety of new morphological and im
munohistological assessment methods, has markedly changed the practice
of breast histopathology. These changes have led to the emergence of
new macroscopic and microscopic interpretation demands and difficultie
s. It is hoped that in the future the role played by diagnostic histop
athology in the management of breast cancer will continue to be refine
d, so that it can provide more detailed information about individual t
umors that will help in deciding the most likely approach to obtain th
e best treatment results. (C) 1996 Wiley-Liss, Inc.
