Will a chest seroma swell again for several days after fluid is drained?

Hello, I discovered a large movable lump in my left chest.
I had an examination last Saturday, and the results showed it is a benign cyst (approximately 5 centimeters).
The doctor mentioned it is benign and used a syringe to aspirate the fluid twice.
However, due to the previous mammogram and ultrasound, I am unsure if the pressure and pain from the needle aspiration are causing some swelling.
Is this a normal situation? The cyst that originally contained fluid has not completely resolved; what does this indicate?

Dear Chen: After aspiration of the cyst, there may still be some swelling.

Generally, we will monitor the situation.
If it continues to enlarge, we may consider aspiration again, or in some cases, surgical excision may be necessary.

It is not uncommon for a breast cyst to remain swollen or to feel tender after aspiration. When a cyst is aspirated, the fluid is removed, but the surrounding tissue may still be inflamed or irritated from the procedure. This can lead to temporary swelling, discomfort, or tenderness in the area.
Breast cysts are fluid-filled sacs that can develop in the breast tissue, and they are typically benign (non-cancerous). The aspiration process involves using a needle to withdraw the fluid, which can provide immediate relief from symptoms such as pain or pressure. However, the cyst may not completely resolve after aspiration, and it is possible for some fluid to remain, or for the cyst to refill over time.
Several factors can contribute to the persistence of swelling or tenderness after aspiration:
1. Inflammation: The aspiration process can cause localized inflammation, leading to swelling and discomfort. This is a normal response of the body to any procedure that involves puncturing the skin or manipulating tissue.

2. Residual Fluid: Sometimes, not all of the fluid can be removed during aspiration, or the cyst may refill with fluid shortly after the procedure. This can lead to a feeling of fullness or swelling in the area.

3. Tissue Reaction: The breast tissue may react to the needle insertion, causing temporary swelling or tenderness. This is similar to how a bruise might feel after an injury.

4. Infection: Although rare, there is a possibility of infection following aspiration, which could lead to increased swelling, redness, warmth, or pain in the area. If you notice any signs of infection, such as fever or discharge, it is important to contact your healthcare provider.

5. Cyst Characteristics: The nature of the cyst itself can also play a role. Some cysts are more complex and may not resolve as easily as simple cysts.
If the swelling and tenderness persist for more than a few days or worsen, it is advisable to follow up with your healthcare provider. They may recommend further evaluation, such as an ultrasound, to assess the cyst and determine if any additional treatment is necessary.
In summary, while it is normal to experience some swelling and tenderness after aspiration of a breast cyst, it is important to monitor your symptoms. If you have concerns or if the symptoms do not improve, do not hesitate to reach out to your healthcare provider for further guidance. They can provide reassurance and help ensure that there are no complications.
