A lipoma is a benign tumor that results from the proliferation of fatty tissue. Lipomas usually present as a tumor-like change that develops as a result of excessive localized accumulation of adipose tissue. Usually the envelope is intact, there is no pain or other inflammatory manifestations, and the growth is slow. When the size of the tumor is too large, it can produce compression symptoms on the surrounding tissues, such as pain and numbness. Lipomas tend to occur in the trunk and back, and are prone to occur in people who often do not bathe or are obese. Lipomas can only be cured by surgical removal, and no other treatment can eliminate them. For smaller lipomas with no clinical symptoms, there is no need for much observation and treatment. If there is progressive enlargement and the phenomenon of redness, swelling and pain, the lipoma can be removed by surgery, and the local area should be kept dry and clean after the operation. The specific treatment can consult the professional physician’s opinion.
