Areolar Sebaceous Glands: Normal or Concerning? - Breast and Thyroid

More Info

---

Areolar sebaceous glands, also known as Montgomery glands, are specialized sebaceous glands located in the areola surrounding the nipple. These glands play a significant role in maintaining the health of the breast tissue, particularly during lactation. They secrete an oily substance that helps to lubricate the nipple and areola, providing a protective barrier against potential infections and irritation.
In your case, the presence of oily marks on your undergarments, particularly around the areola and nipple area, can be attributed to the secretion from these glands. This is a normal physiological phenomenon and is not typically a cause for concern. The oil produced by the areolar sebaceous glands can sometimes be more noticeable, especially if you are experiencing hormonal fluctuations, which can increase the activity of these glands.
It is also important to note that the absence of any discharge from the nipple, along with regular breast ultrasound and mammography showing normal results, further supports the idea that what you are experiencing is a benign and normal occurrence. The oiliness you observe is not indicative of any pathological condition, especially since you have been proactive in monitoring your breast health through imaging studies.

However, if you notice any changes in the characteristics of the oil, such as a change in color, consistency, or if it becomes associated with other symptoms like pain, itching, or any unusual discharge, it would be prudent to consult with your healthcare provider. They may recommend further evaluation to rule out any underlying issues, but based on your description, it sounds like your experience falls within the realm of normal breast physiology.

In summary, the secretion of oil from the areolar sebaceous glands is a normal process and serves an important function in breast health. As long as you continue to have normal imaging results and no concerning symptoms, there is generally no need for alarm. Maintaining regular check-ups and being aware of any changes in your breast health is the best approach to ensure ongoing well-being. If you have any further questions or concerns, do not hesitate to reach out to your healthcare provider for personalized advice.
