I've worked with a fair amount of women over the years who ultimately were
dx with galactocele.  If plugged ducts don't resolve with standard,
conservative measures within about 72 hrs, the lump should probably be
visualized and maybe aspirated to make sure that it is benign and associated
with bfg, not some underlying disease.  The couple of surgeons I usually
refer to use ultrasound.  If a galactocele is identified, there are a few
issues.  One, is the cyst causing repeated episodes of mastitis?  If so, and
if management to improve drainage,etc, fails, it may need to be excised.  If
it is too close to the nipple and causes pain during nursing it may also
require removal.  Many times, however, depending on the size,  it can just
be allowed to stay put.  Usually the surgeon requests a return visit once
weaning occurs to take another look.  If it looks like a smart move, the
cyst can be removed in between pregnancies.
