Why is only one of my nipples leaking?

Understanding Nipple Discharge: Why Only One Nipple Might Leak
Experiencing nipple discharge can be a concerning and confusing issue, especially when it occurs from only one nipple. While it can be alarming, it’s important to understand that nipple discharge can have various causes, some of which are benign, while others may require medical attention.
Normal vs. Abnormal Discharge
Nipple discharge is defined as any fluid that leaks from the nipple, and it can occur in both men and women, although it is considered normal in women or individuals assigned female at birth under certain circumstances. For men, any discharge is typically viewed as abnormal. The nature of the discharge—its color, consistency, and whether it occurs spontaneously or only when the nipple is squeezed—can provide clues about its cause.
Potential Causes of One-Sided Discharge
1. Hormonal Changes: Hormonal fluctuations, particularly those related to the menstrual cycle, pregnancy, or breastfeeding, can lead to nipple discharge. For instance, during pregnancy, some women may notice a yellow or clear liquid, known as colostrum, leaking from their breasts. If the discharge is occurring from one nipple, it could be linked to localized hormonal changes or imbalances.
2. Infections or Inflammation: Conditions such as mastitis or duct ectasia can cause discharge from one nipple. Mastitis, an infection of the breast tissue, often occurs in breastfeeding women but can affect anyone. Duct ectasia, which involves the dilation and thickening of the milk ducts, can also lead to discharge, typically from one side.
3. Benign Growths: Non-cancerous growths, such as papillomas (small, wart-like growths in the ducts), can cause discharge from one nipple. These growths may produce fluid that can be clear, bloody, or even greenish.
4. Medications: Certain medications, particularly those that affect hormonal levels, can lead to nipple discharge. If you have recently started a new medication, it might be worth discussing with your healthcare provider.
5. Breast Cancer: While less common, unilateral nipple discharge can sometimes be a sign of breast cancer, particularly if the discharge is bloody or accompanied by other symptoms such as a lump or changes in the breast’s appearance. However, it’s crucial to note that most cases of nipple discharge are not related to cancer.
When to Seek Medical Advice
If you notice discharge from one nipple, especially if it is accompanied by other symptoms like pain, a lump, or changes in breast appearance, it is advisable to consult a healthcare professional. They can perform a thorough evaluation, which may include a physical examination and imaging tests, to determine the underlying cause and recommend appropriate treatment if necessary.
In summary, while nipple discharge can be a normal occurrence, especially in women, the fact that it is happening from only one nipple warrants attention. Understanding the potential causes and seeking medical advice when needed can help ensure that any underlying issues are addressed promptly.
