Reasons for Breast Discharge
by: Marie DavisSeveral things can cause breast discharge even when you are not pregnant
1) Going off birth control pills
2) Surgery with general anesthesia
3) Frequent nipple stimulation (running or jogging where the nipples are rubbed by clothing, frequent foreplay involving nipple stimulation, etc...)
4) In some cases of Poly Cystic Ovary Syndrome there have been reports of milk production
5) A pituitary tumor - this may cause engorgement and glactorrhea and is almost always bilateral (both sides)
6) Breast cancer-- in this case the discharge is almost always unilateral (one side) and spontaneous in that leakage occurs without any nipple stimulation If you have been pregnant and/or breastfeeding, a drop or two of milk can be expressed long after the pregnancy or breastfeeding period has ended. You should be concerned if the drainage is spontaneous, contains blood, or is accompanied a lump in the breast.
If there is no apparent cause, it is important that you get medical attention (obviously numbers 4,5, and 6 need to see a doctor ASAP). Even if you believe that there is no medical concerns, be sure to let your doctor know at your next visit. Do monthly self breast exams. Self examination saves lives!
