What could cause a dark,, cloudy, almost green colored nipple discharge 9 years after implants?

Thank you for your question.  It is not uncommon for there to be a spontaneous nipple discharge even when you not lactating.  It is not due to your implants.  I recommend an exam by your Ob/Gyn and regular mammograms.

Thank you for your question.  The nipple discharge that you describe is not caused by your breast implants.  Occasionally there is inspissated or retained breast milk in the breast gland that spontaneously discharges.  It is important that you have a breast examination and at least a mammogram done by your primary care physician to check for any underlying abnormality.  In most cases  this is benign.
