Post-Surgery Drainage After Breast Cancer Surgery

Concerns about drainage from the surgical wound after breast cancer surgery?

Hello, Director Tang.
I would like to ask you a question.
My mother previously underwent surgery for breast cancer and was readmitted due to inflammation that caused a large amount of yellow fluid to drain.
She has been home for 9 days now, but the wound continues to discharge a colorless, odorless fluid, estimated at about 1-2 cc per day.
During today's follow-up appointment, the attending physician informed us that this is a normal phenomenon but did not explain why the fluid is being produced.

I found information online indicating that women's breasts produce a small amount of fluid daily, which the body absorbs.
Is the fluid coming from my mother's wound similar to what is produced in women's breasts daily? Additionally, I am concerned that if the wound heals, there might be fluid accumulation in the body.
Would it be possible to detect this through self-examination? I would appreciate your help in clarifying these concerns.
Thank you!

Hello, Miss Xiao Zi.
Based on your description, it appears to be normal tissue fluid.
It is advisable to simply observe the situation, keeping the wound clean and monitoring for any signs of redness, swelling, heat, or pain.
If any abnormalities occur, you should return for a follow-up appointment.
As for fluid accumulation in the body, there may be some slight swelling on the surface, but it still requires evaluation through ultrasound.
If you have any concerns, you may consult with the surgeon.

More Info

After breast cancer surgery, particularly following procedures such as lumpectomy or mastectomy, it is not uncommon for patients to experience drainage of fluid from the surgical site. This phenomenon can be attributed to several factors, including the body's natural healing processes, the presence of surgical drains, and the potential for seromas or hematomas to form.

In your mother's case, the yellow fluid that is being discharged from the wound is likely serous fluid, which is a clear or slightly yellowish fluid that can accumulate in the tissue spaces after surgery. This fluid is part of the inflammatory response and is produced as the body heals. It is important to note that the presence of this fluid is not unusual, especially in the days and weeks following surgery. The body can produce this fluid as a way to protect and heal the affected area.

The amount of fluid your mother is experiencing, approximately 1-2 cc per day, is relatively small and may be considered normal in the context of post-surgical recovery. However, if the fluid continues to drain for an extended period or if there are changes in the color, consistency, or odor of the fluid, it is essential to consult with her healthcare provider. This could indicate an infection or other complications that may require further evaluation.

Regarding your concern about fluid accumulation within the body, it is possible for seromas to develop even after the external drainage has ceased. A seroma is a pocket of clear fluid that can form in the space left by the surgical removal of tissue. Patients may not always be able to feel a seroma, especially if it is small, but larger seromas can cause swelling or a feeling of fullness in the area. If your mother experiences any unusual swelling, tenderness, or discomfort, it is advisable to seek medical attention.

In terms of self-assessment, patients can often monitor their surgical sites for signs of complications. This includes looking for increased redness, warmth, swelling, or any discharge that seems abnormal. Regular follow-up appointments with her healthcare provider are crucial for monitoring her recovery and addressing any concerns that may arise.

It is also worth noting that the body's ability to absorb small amounts of fluid is generally effective, and many patients find that any residual fluid is gradually reabsorbed over time. However, if there is a significant concern about fluid accumulation, imaging studies such as ultrasound may be employed to assess the area and determine if any intervention is necessary.

In summary, the fluid your mother is experiencing is likely a normal part of the healing process following breast cancer surgery. Continuous monitoring and communication with her healthcare team are essential to ensure a smooth recovery. If any new symptoms arise or if there is any doubt about her condition, do not hesitate to reach out to her doctor for further guidance.
