How are lipomas formed? There are many reasons for the formation of lipoma, the specific reasons are not very clear, there may be the following: 1, because this kind of tumor is usually found in the fat-rich parts, so obese patients have a greater chance of developing than ordinary patients. Liu Ming, General Surgery Department, Beijing Haidian Hospital 2. Some of them have family history and are considered to be related to “genes”. 3. Irregular diet can also hurt the liver and spleen, especially those who skip breakfast for a long time and those who eat high cholesterol food for a long time are most likely to suffer from this disease. What are the symptoms of lipoma and how to diagnose it? An experienced doctor can almost always make a definite diagnosis of lipoma in general, and a general surgeon can achieve an accurate diagnosis rate of 70%-80%. Before treatment, surface masses usually don’t need puncture examination, while deeper masses under the skin may not be palpable by hand, but can be diagnosed by ultrasound, which can determine its location, size, texture, and whether it is substantial or cystic. Lipoma can be examined by ultrasound. Hemangioma is relatively difficult to deal with and cannot be operated easily. There may be rich blood vessels inside the tumor, and some of them do not have a clear envelope, and some of them have roots extending into the muscle. Ultrasound can determine the location, size, texture, and whether it is substantial or cystic. If ultrasound is done, the blood supply of the mass can be seen directly, and if the blood supply is rich, it may be malignant; color ultrasound or angiography is necessary, and ultrasound or angiography can clearly determine its boundary, whether the envelope is intact, and the relationship between the surrounding large blood vessels and important tissues such as nerves. How to treat lipoma? Treatment principles: 1.Smaller (within 1cm in diameter), multiple lipomas generally do not need treatment. 2.Larger ones or those with symptoms are suitable for surgical removal. The only effective method of treatment is surgical excision. For multiple cases (some patients can have more than 100), only the more painful ones can be removed first. There is no cure. Most of them are removed surgically under local anesthesia in an outpatient or inpatient day case. What are the dangers of lipomas? Lipoma is a benign tumor that originates from adipose tissue. Most lipomas are solitary, but a few are multiple, clearly defined, lobulated, soft, pseudocystic, and painless. Most of them are small in size, but a few can be 5-6 cm in diameter. Lipomas are composed of differentiated mature adipocytes and are divided into lobules of varying sizes by unequal amounts of fibrous strips. If the fibrous component is high, it is called fibrolipoma, and if the vascular content is abundant, it is called angiolipoma. If a single subcutaneous lipoma causes motor dysfunction, it can be removed surgically; multiple small lipomas do not need to be treated because they are self-limiting and may even disappear on their own; deep lipomas may become malignant, i.e., liposarcoma, so they need to be closely observed and reviewed by ultrasound regularly. If the growth is rapid or the symptoms of pressure appear, surgery should be performed and pathological section should be examined; if it has become liposarcoma, chemotherapy or radiation therapy should be considered after surgery to improve the cure rate. What are the dietary contraindications for liposarcoma? Eat a regular diet, a reasonable and balanced diet, and eat more vegetables and fruits. Eat less greasy and high-fat food. What should be done to prevent lipoma? 1. Pay attention to regular diet and living, more activities and exercise in normal life. 2, in the diet to maintain a light diet, less high-fat, high cholesterol food.
