Soft tissue sarcomas are a group of rare cancers affecting the tissues that connect, support and surround other body structures and organs.

Tissues that can be affected by soft tissue sarcomas include fat, muscle, blood vessels, deep skin tissues, tendons and ligaments. Bone sarcomas are covered separately.

Soft tissue sarcomas can develop in almost any part of the body, including the legs, arms and tummy (abdomen).

They can cause symptoms as they get bigger or spread. The symptoms depend on where the cancer develops.

  • Swelling under the skin may cause a painless lump that cannot easily be moved around and gets bigger over time

  • Swelling in the tummy (abdomen) may cause abdominal pain, a persistent feeling of fullness and constipation

  • Swelling near the lungs may cause a cough or breathlessness

  • You should see a GP if you have a lump – particularly one that's getting bigger over time.


Although it's much more likely you have a non-cancerous condition, such as a cyst (fluid under the skin) or lipoma (fatty lump), it's important to have your symptoms checked.
