Hi,
Most nipple discharges are caused by benign conditions and is rarely a
sign of breast cancer. Fibrocystic breast changes can, at times cause secretion
of clear, white, yellow, or green nipple secretion.
It is meaningless unless your mother notices that the discharge is spontaneous, (comes out without squeezing) is persistent, particularly if it’s bloody and is associated with a lump, nipple or skin changes.
