Many discharges are thick, and yellow, brown or green in color. Because breasts are programed to emit milk when a baby suckles, squeezing your nipple indicates to your body to produce fluid. The more you squeeze, the more you make, Pettinga says. Other women have a condition called galactorrhea, says Simon-Jones. That means your body is producing breast milk.
Some women can spur their body to produce milk just by stimulating their own breasts.
In rare cases, discharge can indicate a small tumor either in the breast or the pituitary gland, where the messages to produce milk come from. However, the fact that you have had this particular discharge for such a long time is even less reason to worry, our experts say. My daughter is just beginning to develop breasts. She asked me why she has a hard circle inside. Your daughter is developing breast buds, says Simon-Jones.
