Have you heard of Pen-Fix from Richard Allan Scientific, I have just
discovered it recently and what a world of difference. What I do is post
fix the breast tissue or any other fatty tissue before I put it on the
machine at the end of the day. Even a little post fixing makes a
difference, the cutting is much better and the pathologists can really
see the difference. Richard Allan gave me all the information  I needed,
procedure and a sufficient sample.  Good Luck.
