Marsha & Winnie, make good points which could provide a possible explanation
of what we "feel" and "thought to be" lactiferous sinuses.
It is interesting that the average areola is around the same diameter,
15-16mm, as the distance that Donna has observed the branching of the
ducts first occurring. As I mentioned before she has also observed some
dilation of ducts where branching occurs. Perhaps this is what we feel, as
Marsha has explained. - and of course with all things there is great
individual variation (as exampled by the variation seen in duct diameter
1-10mm, and so many other things)
Many LCs here in Perth have also voiced this concern "but I can feel them,
they must be there" - particularly in the early weeks when breasts are full.
With such women, where these sinuses appear to be apparent, Donna has imaged
the areola and shown us (LCs) that the ducts are not dilated (in comparison
to further down the duct, away from the nipple).

Actually I donšt believe that concerning research the jury is ever in, but
Donna's work on the live lactating breast, whilst being fed from or
expressed, has provided us with incredible new insights, on which to base
further research and new knowledge. Undoubtedly as research continues to be
built upon, so will our interpretations and our clinical practice change
accordingly, and undoubtedly, also debate will continue on what is the
correct interpretation of what we are seeing.
