What should you know about lipoma cancer?

A typical lipoma is a non-cancerous growth of mature fat cells. It often feels soft or rubbery, sits under the skin, and moves a little when pressed. A lump's location or appearance alone cannot establish its diagnosis, and not every fatty-feeling lump is a lipoma.

Clinicians assess its size, depth, mobility, texture, growth pattern, and symptoms. They may use imaging or arrange removal and laboratory examination when the findings are uncertain. A cancerous soft-tissue tumour is a different condition; only an appropriate medical assessment can distinguish concerning features from a harmless lump.

Arrange a routine appointment if you notice a new lump or are unsure what it is. Note when it appeared, whether it has changed, and whether clothing, movement, or pressure irritates it. Do not squeeze, puncture, or repeatedly manipulate the lump, since that can injure the skin and obscure changes.

If a clinician confirms a lipoma, observation may be reasonable when it is stable and not troublesome. Removal can be discussed when it causes discomfort, restricts movement, or creates persistent concern. A surgical dermatology consultation can explain the likely scar, healing, and whether tissue examination is appropriate.

Seek prompt medical review for a lump that grows quickly, feels fixed or unusually firm, lies deep, becomes persistently painful, or causes weakness or altered sensation. Seek urgent help for severe pain with rapidly increasing swelling, skin breakdown, fever, or sudden loss of function. These signs do not prove cancer, but they should not be ignored.

Does the examination fit a lipoma, and is imaging needed? What changes should I monitor, when would removal be sensible, and would the removed tissue be examined to confirm the diagnosis?
