Nipple discharge


Hello doctor, two weeks ago (two weeks before my period), I noticed that when I squeezed my nipple, a small amount of milky discharge (about the size of a sesame seed) came out.
Throughout this past week, I checked by squeezing my nipple again and there was no discharge.
Today (the fourth day of my period), I squeezed my nipple again and found a small amount of clear, transparent discharge.
Sometimes, there are also small skin flakes around the nipple.
Is this normal? Could it be breast cancer? (There are no visible traces of discharge on my bra.)

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, I’m sorry I cannot diagnose based on the symptoms described, such as lactation.
I recommend seeing a gynecologist for a blood test.
Wishing you good health.

More Info


Nipple discharge can be a concerning symptom for many individuals, particularly when it appears unexpectedly or is associated with other changes in the breast. Understanding whether nipple discharge is normal or a cause for concern involves considering various factors, including the characteristics of the discharge, associated symptoms, and individual medical history.

In your case, you mentioned experiencing a small amount of white discharge from your nipple about two weeks before your menstrual period, followed by a clear discharge during your menstrual cycle. It is important to note that nipple discharge can occur for various reasons, and not all of them are indicative of a serious condition.
Normal Physiological Discharge:
1. Hormonal Influence: Nipple discharge can often be linked to hormonal changes in the body, particularly around the menstrual cycle. The breast tissue is sensitive to hormonal fluctuations, and it is not uncommon for women to experience some discharge related to these changes. The fact that you noticed the discharge before your period suggests that it could be hormonally driven.


2. Galactorrhea: This is a condition characterized by the production of milk or milk-like discharge not associated with breastfeeding. It can be caused by hormonal imbalances, certain medications, or even stress. If the discharge is not persistent and occurs sporadically, it may not be a cause for concern.

3. Physiological Discharge: Some women may experience discharge that is clear, milky, or even yellowish, which can be normal as long as it is not accompanied by other symptoms such as pain, lumps, or changes in the breast tissue.

When to Seek Medical Attention:
1. Persistent Discharge: If the discharge continues or becomes more frequent, it is advisable to consult a healthcare provider. Persistent discharge, especially if it is unilateral (from one breast) or bloody, warrants further evaluation.

2. Associated Symptoms: If you experience any additional symptoms such as breast pain, a noticeable lump, changes in the skin of the breast or nipple, or any other unusual changes, it is essential to seek medical advice.

3. Skin Changes: You mentioned having some small skin flakes around the nipple. While this could be benign, changes in the skin texture or appearance, such as redness, scaling, or irritation, should be evaluated by a healthcare professional.

Breast Cancer Considerations:
While nipple discharge can be alarming and is sometimes associated with breast cancer, it is essential to remember that most cases of nipple discharge are not related to cancer. Breast cancer typically presents with other symptoms, such as a palpable mass, changes in breast contour, or skin changes. However, if you have concerns about breast cancer, especially given your family history or other risk factors, it is prudent to discuss these with your doctor.

Recommendations:
1. Consult a Healthcare Provider: Given your concerns and the changes you have observed, it is advisable to schedule an appointment with a healthcare provider. They may perform a clinical breast exam and, if necessary, recommend imaging studies such as a mammogram or ultrasound to rule out any underlying issues.

2. Monitor Changes: Keep track of any changes in the discharge, including its color, consistency, and frequency. Note any other symptoms that may arise, as this information can be helpful for your healthcare provider.

3. Avoid Self-Diagnosis: While it is natural to seek information online, self-diagnosing can lead to unnecessary anxiety. A healthcare professional can provide a thorough evaluation and appropriate guidance based on your specific situation.

In conclusion, while nipple discharge can be a normal physiological response to hormonal changes, it is essential to remain vigilant and consult a healthcare provider if you have any concerns or if the discharge persists. Early evaluation can help alleviate anxiety and ensure that any potential issues are addressed promptly.
