Nipple Problems and Discharge

What are some common nipple problems?

Nipple conditions are a common
noncancer (benign) breast condition that affect many women. Some problems are related
lactation. Others are not. Like all breast conditions, any nipple problems should
reported to your healthcare provider right away. This can help you get a
prompt diagnosis and start treatment.

What is ectasia?

As a woman nears menopause (around
her late 40s or early 50s), the mammary ducts located under the nipple become widened
(dilated). This normal process of dilation of the milk gland is called ectasia.

Ectasia is a noncancer breast condition. In some cases, it can lead to a blockage
of the ducts. Then fluid may become pooled and leak into the nearby tissue. This causes
infection, chronic inflammation, or a pus-filled infection called an abscess. If there
is an infection (called periductal mastitis), it may cause scar tissue to form. This
draws the nipple inward. This infection may also cause breast pain and thick, sticky
nipple discharge.

Treatment for ectasia

Treatment will depend on your symptoms, age, and general health. It will also depend
on how severe the condition is.

Treatment for ectasia generally involves treating the symptoms. This may include warm
compresses or antibiotics. In some cases, surgery is needed to remove the affected
breast ducts.

What is intraductal papilloma?

An intraductal papilloma is a small, wart-like growth that bumps out into the breast
ducts near the nipple. This causes a bloody or sticky discharge. Any slight bump or
bruise near the nipple can also cause the papilloma to bleed. If the discharge becomes
annoying, the duct can be surgically removed. This can often be done without changing
the look of the breast.

Single papillomas most often affect women nearing menopause. But multiple intraductal
papillomas are more common in younger women. They often happen in both breasts. Multiple
intraductal papillomas are more likely to be linked to a lump than with nipple discharge.
Any papilloma linked to a lump is surgically removed.

What about other types of nipple discharge?

Nipple discharge can be alarming to many women. But discharge that occurs only when
the nipple and breast are squeezed may not be a cause for concern. The risk of cancer
when nipple discharge is the only symptom is fairly low.

A lump with the discharge will be
of primary concern to your healthcare provider. But keep in mind that breastfeeding
women may have a lump under the areola, and discharge. This can be caused by lactational
mastitis that occurs with a pus-filled infection (abscess).

Galactorrhea is a milky discharge
from both nipples, when a woman is not breastfeeding. This is often due to an increase
in the hormone prolactin, which produces milk. This condition may occur if you take
sedatives or marijuana. Or it can be caused by high doses of estrogen. Women who have
this often have irregular menstrual periods. Or their periods have stopped. In some
cases, galactorrhea may be caused by a pituitary gland tumor. You may need blood tests
and an MRI if your healthcare provider thinks you need them.

Nipple discharge that is due to a
noncancer breast condition may be treated by keeping the nipple clean, among other
treatments. Nipple discharge that occurs because of infection may require

How is nipple discharge diagnosed?

Your healthcare provider will likely want to find out if the discharge is coming from
1 duct or several. Multiple duct discharge is nearly always benign. It is likely due
to changes such as ectasia. Discharge coming from a single duct may be more significant.
But if mammography shows no abnormality, surgery may not be needed.

Nipple discharge can be different colors and textures. Your healthcare provider may
take a sample of the discharge and have it checked in a lab to confirm a diagnosis.
