[/INST] Thanks for your question on Chat Doctor. Lipoma is benign soft tissue tumor containing mostly fat tissue. It is subcutaneous in nature and non-tender,non-itchy. Usually no treatment is required. In rare cases it turns into malignancy called liposarcoma. But it is very rare. So your doctor has advice tests to rule out malignant potential of lipoma. So no harm in doing all test. Get done all test. It will come benign only. So no need to worry much. </s>
