Lipoma has the possibility of self-healing, but most lipomas do not heal on their own, and it is a very common benign tumor. The formation of lipoma is complicated, and it is considered to be caused by abnormal local fat metabolism, dietary factors, etc. It is a benign disease, so it is usually not life-threatening. If there is no reaction or characteristic manifestation of lipoma in daily life, treatment is usually not required. However, if the lipoma is large and significantly affects the appearance and causes discomfort, it may be surgically removed. Surgery can be considered as an outpatient procedure under local anesthesia, which is a very simple procedure and does not require much concern. If you have a lipoma, you can control your weight properly because most lipomas are caused by obesity. Therefore, the occurrence and increase of lipoma can be prevented by physical activity and reducing fat intake.
