You can eat it as there is no relationship between potato and lipoma...lipoma isn't cancer and usually is harmless. Treatment generally isn't necessary, but if the lipoma bothers you, is painful or is growing, you may want to have it removed. Surgical removal. Most lipomas are removed surgically by cutting them out. Recurrences after removal are uncommon. Possible side effects are scarring and bruising.A technique known as minimal excision extraction may result in less scarring...Regards.

Hello there.  I can understand your concern.  There is no relation between eating potatoes and lipoma. You haven't mentioned where the lipoma is. Anyways, you can eat potatoes no issues. If you want to get it removed, consult a general surgeon in person for further evaluation and management. Best regards. Dr. Anil kumar jain. Bangalore.
