Any tumor (benign but especially malignant) can recur after removal. Assuming your lipoma is a benign tumor (based on a pathologist's examination of the specimen), the most common cause for recurrence is an incomplete removal the first time around. For this reason, while liposuction of a (benign) lipoma can be done, it is associated with a much higher rate of recurrence.Good luck.
Recurrence, or persistence. of a lipoma can be the result of incomplete removal. This would be more common if the removal was done with liposuction rather than open removal.
