Arly -
Yes, a friend of mine who breastfed 3 children developed an armpit lump
many years after
weaning.  After mammogram, and fine needle aspiration, the benign lump
was removed.
The removal was due to discomfort.  Her doctor's explanation was that
she had simply
continued to develop tissue in that area.   Now, after 3 years, she has
developed an armpit
lump on the other side.  She had a mammogram yesterday and we are
waiting for the
results.

Anyone else?
