The chances of a lipoma becoming cancerous are less than 1%, and the chances of it becoming cancerous are very small. Lipoma refers to a benign tumor of normal fat tissue, with clear boundaries, slow growth, soft texture , and no pain. In some patients, there may be several tens or even hundreds of lipomas, which may grow symmetrically, occasionally with pain, and there is also a certain family history of the disease called lipomatosis. For small and slow-growing lipomas, no special treatment is needed. For large and fast-growing lipomas with symptoms of compression, surgery should be considered, and pathological examination should be performed after the surgery to determine whether there is a lipoma or not, and follow-up observation is needed for lipomatosis. For lipomas, it is recommended to consult the general surgery department of regular hospitals.
