The large pit after lipoma surgery usually grows back in one to two weeks, but the specific time for repairing the surgical area after lipoma excision may vary in different parts and volumes. Lipoma is a common benign tumor in human body, the cause and mechanism of its pathogenesis are still unclear, and there is no drug to control its growth in clinic, the only way to treat lipoma is to remove it through surgery, usually the stitches can be removed one week after surgery, and the wound can be fully recovered one week after the stitches are removed. However, the time needed for different parts of lipoma is also different, the wound of back lipoma can be healed in one week after surgery, while the lipoma of limbs may need two weeks or even longer due to the large tension. If the resected lipoma is large in size, and the fat is not effectively sutured during the operation, the fascia narrows the cavity, or an infection develops in the operation area, the time for the large pit to disappear will be prolonged.
