Are antibiotics required after a sentinel lymph node biopsy?

No: I would think that generally the answer is no as the type of surgery is minimally invasive. However, the surgeon performing the procedure will make that decision by using his best judgment.

No: Often, patients will receive IV antibiotics in the or prior to the procedure, but a prescription for antibiotics afterwards is not necessary.

Not usually: I typically give a dose of antibiotics in the operating room prior to making an incision and do not prescribe antibiotics afterwards unless there is evidence of an infection.
