What is a common complication that can occur following a mastectomy?

After a mastectomy, a seroma is a common complication that may occur. A seroma is a collection of clear fluid that builds up in the space where the breast tissue was removed. This happens because the surgical procedure creates a space that can accumulate fluid as the body heals. It is generally considered a benign condition but can sometimes require additional intervention if the seroma is large or persistent, leading to discomfort or delayed recovery.

Understanding seromas emphasizes the importance of monitoring the surgical site post-mastectomy. While other complications, such as hematomas (which are collections of blood) and infections, can also occur, seromas are particularly frequent after this type of surgery due to the nature of the procedure and the tissue disruption involved. Additionally, pneumonia, while a serious medical concern, does not directly relate to the localized surgical changes that lead to seromas.
