Nipple Discharge

Nipple discharge, especially in women, is a common condition and can often cause concern. The color, amount, and accompanying symptoms of the discharge serve as a guide in understanding the underlying cause.

This condition can be caused by hormonal changes, as well as infections in the breast or benign formations in the milk ducts (e.g., intraductal papilloma). Rarely, malignant tumors can also lead to discharge. Although often not a serious threat, discharges, especially those that are unilateral, bloody, or continuous, should be evaluated quickly.

What Causes Nipple Discharge?

Fluid coming from the nipple is mostly caused by changes in hormone levels, dilated milk ducts (duct ectasia), or benign formations such as intraductal papilloma. The color of the discharge can vary in shades of yellow, brown, or black, and this usually indicates the underlying cause. The treatment strategy is shaped according to the source of the discharge; while some physiological discharges are only monitored, antibiotic use may be necessary in the presence of infection. In cases of benign lesions or more serious pathologies, surgical intervention can permanently eliminate the discharge.

How to Differentiate Normal and Abnormal Nipple Discharge?

Fluid coming from the breast is not always a sign of disease. Some situations can also lead to discharge due to the body's natural processes. Normal discharge, considered physiological, usually affects both breasts and comes from multiple ducts. This type of discharge typically occurs not spontaneously, but with stimulation of the nipple or breast. Its color can be milky white, slightly yellowish, or greenish. If your discharge has these characteristics, there is usually no cause for concern. Additionally, constantly squeezing or checking the nipple can increase discharge, so it is often best to leave it alone.

Which Type of Nipple Discharge Requires Specialist Evaluation?

However, some discharges may indicate an underlying problem and should be addressed carefully. For such pathological discharges, the following situations are considered “red flags” and require specialist evaluation:

• Discharge coming from only one breast
• Discharging spontaneously without squeezing the breast and staining underwear
• Fluid coming from a single duct in the nipple
• Continuing persistently and not temporarily
• Its color being clear, bloody (red, pink, brown) or watery
• Presence of a palpable mass in the breast accompanying the discharge
• Observation of retraction, thickening, or discoloration in the nipple or skin

If one or more of these characteristics are present, it is important to consult a specialist without delay to determine the underlying cause and plan the necessary treatment.

What Does the Color of Nipple Discharge Tell Us?

The color of the fluid coming from the nipple can offer important clues about possible causes. However, color alone is not sufficient for diagnosis; it should be evaluated along with other characteristics of the discharge. It can be helpful to drop the discharge onto a white tissue to observe its color clearly. Common colors and their possible meanings are:

Milky White: Generally physiological, non-concerning discharges.

Yellow / Green: May result from fibrocystic changes or duct ectasia (dilation of milk ducts).

Brown / Black: Mostly benign duct dilations seen in pre- and post-menopausal periods.

Clear / Watery: If unilateral or spontaneous, it may indicate a pathological process.

Bloody / Pink: May indicate benign intraductal papilloma or, rarely, malignancy.

Pus-like (Purulent): Indicates the presence of infection.

Yellow or green tones generally indicate non-serious, benign processes. Black discharges are also mostly benign and are particularly seen in women approaching menopause. However, clear or bloody discharges are more noteworthy and, if unilateral and spontaneous, definitely require further evaluation.

Benign Conditions Causing Nipple Discharge

Most of the time, nipple discharge results from non-cancerous, benign causes. This is reassuring information for women. The most common benign causes are:

Duct Ectasia

This is a common condition in women aged 40–50. The milk ducts behind the nipple naturally widen, their walls thicken, and they can fill with fluid. Smoking can trigger this condition. It usually leads to sticky, green, brown, or black discharge. This condition resolves on its own and does not increase the risk of breast cancer.

Intraductal Papilloma

This is the most common cause of pathological discharge. It is a benign, wart-like tumor that develops inside the milk duct. Its structure is rich in blood vessels and can bleed easily; therefore, it causes unilateral, spontaneous, and bloody or clear discharge. Although benign, it can rarely contain atypical cells or early-stage cancer cells around it. For this reason, surgical removal of symptomatic papillomas is a standard approach. The operation both stops the discharge and allows for a definitive diagnosis by examining the entire lesion.

What is Nipple Discharge Caused by Galactorrhea?

Galactorrhea is the discharge of milk-like fluid from both breasts, unrelated to pregnancy or breastfeeding. This condition is not directly a breast disease; it is mostly an indicator of hormonal imbalances in the body. High levels of prolactin hormone, which is responsible for milk production, in the blood (hyperprolactinemia) lead to galactorrhea. Unilateral discharge is rare; it usually comes from both breasts simultaneously.

Some conditions that can cause galactorrhea include:

• Some antidepressants, antipsychotic medications, or blood pressure medications
• Benign tumors in the pituitary gland that produce prolactin (prolactinoma)
• Insufficient secretion of thyroid hormone (hypothyroidism)
• Chronic kidney failure
• Excessive stress and psychological factors

Can Breast Infections and Abscesses Cause Nipple Discharge?

Yes, absolutely. Breast tissue infections, known as mastitis, or abscesses that develop if left untreated, can lead to purulent and foul-smelling discharge. In such cases, the discharge is usually accompanied by other symptoms in the breast. The most common symptoms are:

• Severe pain and copious discharge
• Tenderness and swelling in the breast
• Redness and increased warmth in the affected area
• In some cases, fever and fatigue

What is the Connection Between Nipple Discharge and Breast Cancer?

The most common concern and question among women is whether nipple discharge is a symptom of cancer. Nipple discharge can rarely be the first sign of cancer. In a very small percentage of women diagnosed with breast cancer (less than 5%), discharge is the first and only symptom of the disease.

However, studies on women who present with unilateral, spontaneous, and bloody or clear discharge show that the probability of the underlying cause being cancer ranges from 5% to 21%. Although this rate may seem low, it indicates that suspicious discharges must be taken seriously and thoroughly investigated.

Can Ductal Carcinoma in Situ (DCIS) Cause Nipple Discharge?

Yes, DCIS can rarely cause nipple discharge. DCIS is an early-stage (Stage 0) breast cancer type that has not spread beyond the milk ducts. Most of the time, it does not cause symptoms and is detected through small calcifications (microcalcifications) during routine mammography screenings. However, in some cases, it can manifest as bloody or clear discharge. This condition should be taken seriously because if left untreated, there is a risk of it progressing to invasive cancer. Therefore, determining the reason behind such a discharge is of critical importance.

The Relationship Between Paget's Disease of the Nipple and Discharge

Paget's disease of the nipple is a rare type of cancer that affects the nipple and the dark area around it (areola). It often resembles eczema, which can delay its diagnosis. This disease is usually an indicator of DCIS or invasive cancer spreading from the milk ducts to the skin.

Its symptoms include:

• A non-healing, red, scaly, and crusted rash on and around the nipple
• Itching or burning sensation
• Yellowish or bloody discharge
• Retraction or flattening of the nipple

If you notice a persistent eczema-like lesion on your nipple, it should be evaluated without delay. Diagnosis is made with a small biopsy taken from the nipple skin.

Methods Used to Determine the Source of Nipple Discharge

To create a correct treatment plan, the cause of the discharge must first be clearly identified. This process begins with a detailed patient interview and includes physical examination and imaging methods. The general steps followed are:

Patient History and Physical Examination

The onset time of the discharge, triggering factors, and other symptoms are questioned in detail. Afterwards, both breasts and armpits are carefully examined to look for masses or other abnormalities.

Imaging Methods

Mammography and breast ultrasound are used together depending on age and findings. For women under 30, ultrasound is usually the preferred choice. These tests help visualize the inside of the milk ducts and possible lesions such as masses, duct ectasia, or intraductal papilloma.

Breast MRI (Magnetic Resonance Imaging)

Even if mammography and ultrasound results are normal, if the characteristic of the discharge (e.g., bloody) raises suspicion, Breast MRI may be performed. This method provides high sensitivity in detecting hidden lesions that cannot be identified with other tests.

Why is Nipple Discharge Important in Men?

Any nipple discharge in men is not considered normal and must be evaluated. This condition, which is much rarer in men than in women, can be associated with a serious cause, especially breast cancer, in a high percentage of cases. Research shows that the rate of cancer detection in men who present with nipple discharge can be as high as 23%. Therefore, discharge observed in men should be examined by a specialist without delay.

Treatment Methods for Nipple Discharge

The treatment approach depends entirely on the underlying cause:

Physiological or simple duct ectasia related discharges: Often no intervention is needed; regular follow-up is sufficient.

Infection-related discharges: Appropriate antibiotic treatment is applied.

Hormonal imbalances (galactorrhea): In this case, the hormonal problem causing the discharge is corrected.

Benign lesions and suspected cancer: Surgical intervention may be necessary.

Surgical options include:

Microdochectomy

This is the procedure of removing only a single problematic milk duct through a small incision around the nipple. It is particularly suitable for young women with single-duct discharge who plan to breastfeed in the future.

Total Duct Excision

If the problem is not limited to a single duct or if there are recurrent infections, all main milk ducts behind the nipple are removed. After this procedure, the ability to breastfeed from that breast is lost.

Cancer Surgery

If the cause of the discharge is breast cancer, treatment is determined according to oncological principles. Depending on the type and stage of cancer; operations involving the removal of a part of the breast (breast-conserving surgery) or the entire breast (mastectomy) may be performed.
