Dear Adrienne, A papilloma is a wart like growth that can occur in the lining of the duct of the breast. Papilloma's do not go away on their own. You say it is a possible papilloma, has it been fully evaluated to be sure of what this is?
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 varying shades of 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.
The time to worry about nipple discharge is when it’s spontaneous (comes out by itself without squeezing), keeps on happening, and is only on one side. If it is clear and sticky, like an egg white, or bloody. If these symptoms are present further evaluation to be sure of the cause of the discharge is prudent.
