there is nothinig about sticky in your path report except perhaps indirectly lymphovascular invasion as the cells are thought to become unsticky before they squeeze their way between the sieve-like spaces between tiny blood vessel lining cells to get into the blood or lymph channels to go elsewhere.

This is inferred I think and not proven (see my next post, as another long held assumption is being questioned ie, that it is good to give glucocorticoids like dexamethasone with chemo)

Ecadherin and alpha and beta catenin are not generally stained for by pathologists--they are things research scientists are interested in in trying to unravel how breast cancer does the things it does.
