RE: Microwave Processing Should Be Banned

I am sure that microwaving "done properly" works fine. In reality, specimens
are batched in groups and treated like McDonald's handles french fries. A
bad "batch" affects scores of diagnoses.

Jonathan raises an interesting point, which I hope will be addressed by
someone with more experience and knowledge than I, about cells being
In Matilda Beyer-Boon's book, called something like 'The Microwave
Cook-book', she makes the point that microwaving done properly decreases the
time takes for all the cross links to take place. However, this can only
occur when the formalin is in contact with the cell. In other words,
microwaving prior to penetration of the fixative, is cooking. After
penetration of the fixative, it is augmentation/speeding up.

Does microwaving tissue cause damage. Sure does. And it destroys cytologic
The procedure COOKS the chromatin and destroys nuclear detail, destroying
the opportunity to recognize cancer when it is present in small quantities.
I have seen this again and again on specimens sent to me for a second
opinion. Hey, it speeds up turn around time. It ain't worth it. . . . . Just
one pathologist's strongly held opinion.
