Hello and thanks for your enquiry,

While most nipple discharge is caused by benign (non-cancerous) conditions, the clear or orange tinted fluid from a single breast, can also be a sign of an underlying breast issue.

Some women are just more prone to developing certain breast conditions. Medications or changes in hormone levels can cause nipple discharge. Also, the breast mammary ducts can get bigger with age, or there can be minor breast duct infections. Sometimes an intraductal papilloma (small benign growth in a duct) can cause nipple discharge. It is less likely overall to be related to a breast cancer.

However, anything new or persistent should be checked out again, for peace of mind, and to get a steer on what's causing it.

I hope that this reply helps,

Best wishes,

Vanda
