The short explanation
Often, yes. A little milky, clear, yellow or green fluid from both nipples when squeezed is common, particularly in women who have been pregnant, and usually has a harmless cause. Squeezing to check tends to keep it going, so it is worth stopping. Discharge that comes out on its own from one nipple, from a single duct, or that is bloody or watery-clear, is different and should be examined.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Milky discharge from both sides when you have not recently breastfed can come from raised prolactin, which has its own causes — some medicines, thyroid problems, and occasionally a small benign growth in the pituitary gland — and is often accompanied by irregular or absent periods. A blood test is the usual first step.
- Many cases of single-duct discharge are caused by a small benign growth inside a duct, but it needs checking to be sure.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what is causing your discharge. Colour and amount are clues, not a diagnosis, and only an examination and sometimes tests can say.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is this the kind of discharge that needs tests?
- Should my prolactin or thyroid be checked?
- Could any medicine I take be causing it?
- Do I need an ultrasound or mammogram?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
- See a clinician within days for bloody discharge, discharge from one nipple that comes on its own, discharge with a lump, or a nipple that has newly turned in or has a scaly rash.
- Book a routine appointment for milky discharge from both sides, especially with changes to your periods.
