No: An ultrasound can not differentiate the fat that makes up a lipoma from the surrounding fatty tissues under the skin and will not definitively be able to differentiate a cancer from a non-cancer. If the lump is hurting then have it removed and it should be sent for pathological analysis. That will tell you if it is a cancer (Malignancy) or not. A true lipoma is not typically dangerous.
