Nipple discharge


Hello Doctor, I would like to inquire about something.
Last Saturday, during intimacy with my husband, I noticed white discharge from my right nipple (similar to a white and transparent pimple).
I have been observing it for the past two days, and when I squeeze it, there is a slight discharge that comes out for 2 to 3 squeezes, but then it stops.
Is this a normal phenomenon?

Dear Duck: It's generally normal, but if there are any blood-tinged or foul-smelling discharges, a clinic visit for examination is necessary.

Nipple discharge can be a concerning symptom for many individuals, and understanding its nature is crucial in determining whether it is normal or warrants further investigation. In your case, you mentioned observing white and transparent discharge from your right nipple, which occurred during intimacy with your partner. You also noted that you could express some discharge by squeezing, but it was limited to a few instances before stopping.

Firstly, it is essential to recognize that nipple discharge can occur for various reasons, and not all of them are indicative of a serious medical condition. Normal physiological discharge can happen due to hormonal changes, especially in women. For instance, during menstrual cycles, pregnancy, or breastfeeding, hormonal fluctuations can lead to increased discharge from the nipples. In some cases, even non-pregnant women may experience discharge due to hormonal imbalances or stimulation of the breast tissue.

The characteristics of the discharge are also significant. Clear or milky discharge can be benign, particularly if it is bilateral (affecting both breasts) and not associated with any other symptoms such as pain, lumps, or changes in the breast tissue. However, if the discharge is unilateral (affecting one breast), persistent, or accompanied by other concerning symptoms, it may require further evaluation.

In your situation, since the discharge appears to be limited and not accompanied by other symptoms, it may not be a cause for immediate concern. However, it is essential to monitor the situation. If the discharge becomes persistent, changes in color or consistency, or if you notice any lumps, pain, or changes in the breast, it would be prudent to consult a healthcare provider.

Additionally, certain conditions can lead to nipple discharge that may require medical attention. These include:
1. Duct Ectasia: This condition occurs when a milk duct beneath the nipple dilates, fills with fluid, and thickens. It can lead to discharge and sometimes pain or tenderness.

2. Intraductal Papilloma: This is a benign tumor that forms in the milk ducts and can cause discharge, often bloody or clear.

3. Galactorrhea: This is a condition characterized by the production of breast milk in individuals who are not breastfeeding. It can be caused by hormonal imbalances, medications, or other underlying conditions.

4. Breast Cancer: While less common, certain types of breast cancer can present with nipple discharge, especially if it is bloody or associated with a lump.

In summary, while your observation of white and transparent discharge may not be immediately concerning, it is essential to remain vigilant. If you notice any changes or if the discharge persists, seeking medical advice is advisable. A healthcare provider can perform a thorough evaluation, which may include a physical examination, imaging studies, or laboratory tests, to rule out any underlying conditions and provide peace of mind. Always prioritize your health and well-being by staying informed and proactive about any changes in your body.
