Q: Good evening ma’am. I noticed milk-like fluid coming from my breast, but I’m not breastfeeding. What could be causing this?

A: Thanks for your question.

Here are 5 things you should know about nipple discharge:

1) The colour does not always tell the whole story

Discharge can be milky, clear, yellow, green, or bloody. The colour alone does not always determine whether it is normal or abnormal.

2) It can happen even if you are not pregnant

Milk-like discharge outside breastfeeding is called galactorrhea, often caused by the hormone prolactin.

3) Several things can cause it

Possible causes include:

• Hormonal imbalance

• Certain medications

• Breast infections

• Injury to the breast

• Excess nipple stimulation

• Rarely, breast cancer

4. It can happen in men and babies too

Galactorrhea can occur in men and newborn babies due to hormone effects.

5. Some types should be checked urgently

See a doctor if the discharge is:

• Bloody

• From one breast only

• Occurring without touching the breast

• Associated with a lump

Bonus Health Tip

Treatment depends on the underlying cause.

For example:

• If caused by medication, your doctor may adjust or change the drug

• If due to high prolactin levels, medications can help reduce it

• If due to infection, antibiotics may be needed

• If due to a tumour producing prolactin, treatment may include medication or surgery

Most cases improve once the cause is identified and treated.

If you notice persistent nipple discharge, please see your doctor for evaluation.
