Book an appointment
If you have been treated for sarcoma, contact your follow-up team about a new lump, increasing pain, unexplained weight loss, a persistent cough, new breathlessness, or symptoms that do not settle.
Every sign above is quoted from the sofidex article on Soft tissue sarcoma. If you are not sure, err upward — it is always reasonable to be checked.
