The most common symptoms of soft tissue sarcoma are:
- a growing lump under the skin, often on an arm or a leg – this may be either painless or painful
- trouble breathing.
Symptoms of sarcoma in the bone include:
- for osteosarcoma, swelling over a bone, or pain in a bone
- for Ewing sarcoma, pain and/or swelling or a lump in the area of the tumour, such as the arms, legs, chest, back or pelvis – the lump is often soft and feels warm
- for Ewing sarcoma, fever for no known reason
- a bone that breaks for no known reason.
Gastrointestinal stromal tumours may not cause any symptoms until they reach a certain size. Very small tumours are common, and some of these will not grow or spread.
Symptoms of gastrointestinal stromal tumour can include:
- blood in the stools or vomit
- black, tarry stools
- abdominal pain
- swelling in the abdomen
- nausea and vomiting
- loss of appetite, and feeling full after only a little food has been eaten
- weight loss
- feeling very tired
- trouble swallowing (if the tumour is in the oesophagus).
There are a number of conditions that may cause these symptoms, not just sarcoma. If any of these symptoms are experienced, it is important that they are discussed with a doctor.
