Lipoma can be left untreated when it is small, asymptomatic and slow-growing; surgical resection is necessary when the tumor increases in size and exerts pressure on the surrounding tissues and other related symptoms. Lipoma is a common benign soft tissue tumor, which can grow in any part of fat tissue, grow slowly and usually without symptoms. When the mass increases in size and compresses the surrounding tissues and nerves, numbness and pain may occur. Clinics often do not take special treatment for small, slow-growing, asymptomatic people, and regular observation is enough; surgical resection can be taken when the tumor grows fast and pressure symptoms appear. Lipoma patients should pay attention to monitoring the change of symptoms, and consult the doctor for surgical treatment in time when discomfort occurs.
