Duct normal
Duct is considered normal.
It is surrounded by normal cells and collagen in
the breast with no abnormalities.
A system of ducts in the breast carries milk to the
nipples.
SolitaryDilatedDuct
Solitary dilated duct
When it is malignant, solitary dilated duct appears
to indicate the presence of DCIS.
In almost all solitary dilated duct cases, the dilated
duct appears to be filled with some debris, with
or without accompanying fluid, as seen at ultrasound.
DuctEctasia
Duct ectasia
A noncancerous condition that results in clogged
ducts around the nipple.
While it sometimes causes pain, irritation and discharge,
it's generally not a cause
for concern.
If left untreated, it can eventually obliterate the
breast duct.
