Nipple discharge

Is nipple discharge concerning?

Nipple discharge is a fairly common finding amongst women, especially in women who have breastfed in the past. Most types of nipple discharge are completely benign, especially if the discharge is milky or green in nature and comes out of multiple ducts (openings) on the nipples and out of both breasts.

Occasionally, nipple discharge is a sign of a more serious underlying condition and needs further investigation or surgery. This is more likely if the discharge is bloody or serous (clear) in nature, happens spontaneously and comes out of one duct. The most common cause for this type of discharge is an intraductal papilloma (benign polyp), but it can also be caused by DCIS (Ductal Carcinoma In Situ).

Do I need an operation?

In the event of nipple discharge, Dr Bell will take a detailed history and order the necessary investigations. If the discharge is bloody or serous (clear) in nature, comes from a single duct and is spontaneous, it is likely that Dr Bell will recommend an operation. This may entail a microdochectomy (removal of the single affected duct) or a central duct excision (removal of all the ducts from underneath the nipple).
