There is a kind of tumor that does not need to worry too much 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 human limbs, back and waist. 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 watery, 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 grow over years and years to form huge masses. What is a multiple lipoma? Anytime there are two or more lipomas is a multiple lipoma, and many people have multiple lipomas, sometimes it is just other lipomas that have not yet been detected. Patients with multiple lipomas often have a family history of multiple lipomas, 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. In some cases, which are more difficult to determine, the diagnosis can be clarified by pathological examination after excision. Morphological features of multiple lipomas: Lipomas usually grow under the skin on the surface of the body as superficial lipomas, such as those growing on the shoulder, neck, chest, buttocks, and proximal extremities, etc. There are also lipomas that grow deeper, such as those growing in the intermuscular 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 feel painful when pressed, and they have clear borders when pushed by hand and have fluctuating sensations when pressed, 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 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 multiple lipomas. Is it true that fat people are prone to have lipomas? In fact, lipoma is not related to 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, and factors affecting metabolism will also affect the generation of lipoma. The causes of multiple lipomas are not clear, but most people believe that they are related to genetics and poor diet, and mental factors are also an important cause of multiple lipomas. For the prevention and control of multiple lipoma should do the following: 1, a light diet, more vegetables, more legumes; 2, strict control of the intake of staple foods, do not aggravate 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, not to skip breakfast; 5, do not often angry, because anger will hurt the liver.
