Breast seroma


After the aspiration of a cyst, it has been one month, and upon self-examination, I still feel a hard lump.
Is this a normal phenomenon? Thank you.

Hello Ms.
Wang: After aspiration of a cyst, it is possible to still feel a lump, as there may be reaccumulation of fluid in the cyst, or the cyst wall may be thickened, giving a lump-like sensation.
If you notice that it has increased in size or recurs, surgical excision is recommended.

More Info


After undergoing a cyst aspiration, it is not uncommon to feel a firm area in the breast tissue during self-examination. This can be attributed to several factors related to the procedure and the natural healing process of the breast tissue.

Firstly, it is important to understand that cyst aspiration involves the removal of fluid from a cyst, which can lead to changes in the surrounding breast tissue. The aspiration may cause temporary inflammation or irritation in the area, which can result in a palpable firmness. This firmness is often due to the body’s natural healing response, where the tissue may swell slightly as it recovers from the procedure.

Additionally, the breast is composed of various types of tissue, including glandular, fibrous, and fatty tissues. After the removal of a cyst, the remaining tissue may feel different than before. It is also possible for the breast tissue to have some residual changes, such as fibrosis, which can create a firm area that may be mistaken for a new lump. This is particularly common in women with dense breast tissue.

It is essential to monitor any changes in the breast over time. If the firmness persists or if you notice any new symptoms such as pain, changes in the skin, or discharge from the nipple, it is advisable to consult with a healthcare professional. They may recommend further imaging studies, such as an ultrasound or mammogram, to evaluate the area and ensure that there are no complications or new developments.

In general, the presence of a firm area after cyst aspiration can be considered normal, especially if it gradually decreases over time. However, every individual’s situation is unique, and factors such as your personal medical history, the size and nature of the cyst, and any accompanying symptoms should be taken into account.

In summary, while it is common to feel a firm area in the breast after cyst aspiration, it is crucial to remain vigilant about any changes and to seek medical advice if you have concerns. Regular breast self-examinations and routine check-ups with your healthcare provider are important for maintaining breast health and addressing any potential issues early on.
