Whether lipomas need surgical treatment often depends on the location, size of the lipoma, and whether it causes related clinical symptoms. If the lipoma grows too fast during observation, is in a special location, or severely affects appearance, surgical treatment can be considered. Alternatively, if the lipoma shows evident symptoms like localized redness, pain, surface itchiness, and uneven surfaces, timely color ultrasound re-examination should be done as malignancy cannot be ruled out, and timely surgical removal and biopsy are necessary. Thirdly, if the lipoma grows too quickly and causes compression symptoms, damaging other organs, surgical treatment should also be considered. Generally, lipomas are benign lesions, but there is also a possibility that they could develop into liposarcomas, which should be confirmed based on postoperative biopsy.
