About this Treatment: Breast Conserving Surgery/Lumpectomy
Risks of Breast-Conserving Surgery
Complications following breast cancer surgery are rare, but can include:
Hematoma
This is when the surgery site fills up with blood and there is a sudden onset of swelling and pain. This is a complication that requires urgent medical intervention.
Infection
Signs of infection include redness, a fever, chills, nausea, vomiting, pain at the incision site, or discomfort that medicine does not control.
Seroma
Excess fluid build-up at the surgery site, after lumpectomy or mastectomy. Signs of seroma include increasing swelling, increasing pain, opening or drainage from the incision.
