Could a small seroma in the abdomin be dangerous?

A seroma is a small fluid collection usually under an incision.

seroma: filled with clear serous fluid hematoma: filled with red blood cells

seroma is a tumor-like collection of serum, whereas ceroma is a tumor of degenerated tissue.

The most common complication that arises from having a seroma is the repeated visits required to have the seroma drained. You may also find your initial recovery period delayed or even more difficult than expected.
