Dear Mystic, Many women have some type of nipple discharge or fluid when their breasts are squeezed, and its normal. Squeezing the nipple sends message to the brain and the pituitary gland responds by increasing prolactin levels, which in turn produces discharge from the nipple. The discharge can come in a variety of colors – gray, green and brown as well as white. Some women are more prone to more discharge including women on; birth control pills, certain blood pressure medications or on major tranquilizers. These medications increase prolactin levels in the body. There is also certain life periods when a person is more likely to get discharge than others: there may be more discharge at puberty and at menopause than the years in-between.
Of concern with nipple discharge if it is spontaneous (occurs on its own without squeezing) or if it is bloody. This is something that should be followed up on.
Your symptoms could be attributed to many things. It is best to be evaluated by a health care professional who can ask questions, do a physical exam and put this in context of your situation.
