The causes of lipoma are not very clear for the time being, and may be related to genetic factors, bad living habits, poor diet and so on. 1. Genetic factors: if there is a history of lipoma in the immediate family, genetic factors may play a role in lipoma, and the chance of developing lipoma will be higher. 2. Bad living habits: if you often stay up late at night or frequently change your life from black and white, it may lead to a decrease in the body’s ability to break down fat, and the original adipose tissues and the newborn adipose tissues may be arranged abnormally, which may lead to lipoma. 3. Bad diet: If you drink too much alcohol or eat too much high cholesterol food in your daily life, it may lead to the accumulation of too much fat in your body, which may cause lipoma. Lipoma is a common benign tumor of soft tissues and can grow in any part of the body where there is fatty tissue. Lipomas can be left untreated if there are no obvious symptoms or if they do not affect the appearance of the skin. If there are obvious symptoms or if it affects the aesthetic appearance, the treatment is mainly surgical removal.
