There is a kind of tumor that does not need too much worry as long as it is not located in the abdominal cavity. It grows very slowly and looks lovely round or oval in appearance, and it mostly resides in the limbs, back and waist of human body. I. What is lipoma? Lipoma is a common benign tumor that is a verrucous form of normal fat-like tissue. It can grow anywhere on the body, preferably on the extremities and trunk. They often appear as single and multiple subcutaneous confined masses that are soft and have a cystic feel to the touch. It is usually asymptomatic unless the tumor is large enough to interfere with movement or causes pain due to pressure on nerves. As a common benign soft tissue tumor, lipoma changes extremely slowly, but a few tumors can form huge masses after years and years of growth. 2. What is multiple lipoma? As long as there are two or more lipomas are multiple lipomas, many people have multiple lipomas, sometimes it is just other lipomas that have not been detected yet. Patients with multiple lipomas often have a family history of the disease, and some have painful masses, also known as “painful lipomas”. Larger or symptomatic masses can usually be removed for pathological examination to clarify the diagnosis, but not all of them. Lipomas are rarely malignant and do not pose a significant risk to the body. In general, lipomas can be diagnosed clinically through examination by a physician, appearance and clinical presentation. Benign lipomas are usually smooth, soft and mobile to the touch. Conversely, if the mass increases rapidly in a short period of time or appears to be unsmooth, gradually hard in texture, and fixed under the skin, it is important to seek medical attention as soon as possible to rule out malignant masses and remove them if necessary. For some of them which are more difficult to determine, the diagnosis can be clarified by pathological examination after removal. Morphological characteristics of multiple lipomas Lipomas usually grow under the skin on the surface of the body, as body surface lipomas, such as growing in the shoulder, neck, chest, buttocks, proximal part of the limbs, etc. There are also lipomas that grow deep, such as growing in the muscle space, tissue space, and retroperitoneum. In general, the proportion of lipomas in middle-aged people and women is higher. Most of the lipomas on the surface of the body are benign, soft to the touch, most of them do not have painful pressure, and when pushed by hand, they have clear boundaries and fluctuating pressure, which do not have much impact on life and living. Liu Chao said that liposarcoma on the body surface can be easily confused with powdery tumor, superficial hemangioma, lymphangioleioma and neurofibroma, but the diagnosis can be finally confirmed by ultrasound. Liposarcoma is insensitive to drugs and radiotherapy and chemotherapy, and surgical excision is the most direct and effective method. As long as the surgery is performed in a regular hospital and the excision is clean, there is usually no recurrence, unless it is a multiple lipoma. Is it that fat people are prone to have lipoma? In fact, lipoma has little to do with body shape, many thin people will also grow lipoma, which is more related to metabolism, people with high blood lipids are more likely to get lipoma than the average person, factors affecting metabolism will also affect the generation of lipoma. The cause of multiple lipoma is not clear, but most people believe that it is related to genetics and poor diet. For the prevention and control of multiple lipoma, the following points should be done: 1. Eat a light diet, more vegetables and more legumes. 2.Strictly control the intake of staple food, do not increase the burden on the liver. 3, keep a happy spirit, to be in a relaxed and happy mood active treatment. 4, three meals a day should be regular, to eat on time and on schedule, not to skip breakfast. 5, do not often angry, because anger can hurt the liver.
