Breast Lumps: Diagnosis and Concerns About Inflammation

There is a lump located directly beneath the nipple?

Hello Dr.
Wu, I would like to ask about the three steps for checking breast cancer: ultrasound, cytology, and pathological tissue biopsy.
Is the final pathological tissue biopsy the most accurate result? If so, should I not worry too much if the pathological report for a lump directly beneath the nipple indicates inflammation? Will the lump change over time if it persists? The doctor mentioned that the lump under the nipple is a sebaceous cyst.
Does a sebaceous cyst grow slowly? Why is inflammation equated with a sebaceous cyst? Thank you, Dr.
Wu, for your hard work!

Dear Miss YOYO,
The pathological examination of tissue samples is indeed the most accurate result.
If the pathology report for the mass located directly beneath the nipple indicates inflammation, there is no need to worry too much at this stage.
The mass may persist as a result of the inflammatory response; regular self-examinations and periodic follow-up visits to the outpatient clinic are sufficient.
A sebaceous cyst can gradually enlarge and may become inflamed due to infection, which are two different conditions.
Wishing you good health,
Dr.

When it comes to breast health, understanding the nature of lumps and the diagnostic process is crucial. The three-step approach you mentioned—ultrasound, cytology, and pathological tissue biopsy—is indeed a standard protocol for evaluating breast abnormalities. Each step serves a specific purpose in diagnosing potential issues, including breast cancer.

1. Ultrasound: This imaging technique helps visualize the structure of the breast tissue and can differentiate between solid masses and fluid-filled cysts. It is particularly useful for examining lumps that are palpable but not visible on a mammogram.

2. Cytology: This involves collecting cells from the lump (often through fine needle aspiration) to examine them under a microscope. It can provide preliminary information about whether the cells are benign or malignant.

3. Pathological Tissue Biopsy: This is the definitive test. A biopsy involves removing a small sample of tissue from the lump for detailed examination. The pathologist will look for cancerous cells and determine the nature of the lump.

If your pathological report indicates inflammation, it typically means that the lump is not cancerous. Inflammation can arise from various causes, including infections, trauma, or benign conditions like a cyst or a fibroadenoma (which is often referred to as a "phyllodes tumor" or "fibroadenoma"). While inflammation itself is not a cause for alarm, it is essential to monitor the lump for any changes over time.

Regarding your concern about the lump under the nipple being a "lipoma" (which is a benign tumor of fatty tissue), it is important to clarify that while lipomas can grow slowly, they are generally not associated with cancer. However, any persistent lump should be evaluated regularly, especially if it changes in size, shape, or texture.

Inflammation does not equal a lipoma; rather, inflammation can occur in various conditions, including infections, cysts, or even benign tumors. The presence of inflammation indicates that the body is responding to some form of irritation or injury, which could be due to a variety of factors.

In terms of monitoring, if the lump remains stable and the inflammation resolves, it may not require immediate intervention. However, if you notice any changes—such as increased size, pain, or changes in the skin over the lump—it's essential to follow up with your healthcare provider. Regular check-ups and imaging studies, such as ultrasounds, can help ensure that any changes are detected early.

In conclusion, while a pathological report indicating inflammation is generally reassuring, it is crucial to maintain vigilance regarding any breast lumps. Regular follow-ups with your healthcare provider, self-examinations, and imaging studies as recommended can help ensure your breast health remains a priority. If you have any further questions or concerns, don't hesitate to reach out to your healthcare provider for personalized advice and guidance.
