Lipoma is a benign tumor that usually does not require surgical treatment, and can usually be surgically removed if it is larger than 5cm or if pressure symptoms occur. Generally, lipoma larger than 5cm may affect the aesthetics, located in special location such as back, may cause discomfort to the patient due to compression while sleeping, and can be removed through surgery. Some lipomas may be small in size, but due to their special location, such as pressing on nerves, blood vessels, joints, leading to pain, blood circulation disorders or joint mobility disorders, etc., they also need to be surgically removed to relieve a series of symptoms caused by the tumor. If the growth of lipoma is accelerated and there is a tendency of malignant transformation, surgical resection is also needed, and pathological examination is done to exclude malignant lesions. If a lipoma is present, you can seek medical attention and choose the appropriate treatment under the advice of your doctor.
