Signs and Symptoms of Bone and Soft-tissue Sarcomas 

Soft-tissue Sarcoma Symptoms 

The first noticeable sign of soft-tissue sarcomas (STS) in the legs, arms, or trunk (where most soft-tissue sarcomas start) is usually a painless lump or swelling under the skin. Most lumps are harmless (benign or non-cancerous), but those that are growing require immediate medical attention. STS that begin other places in the body like the abdomen may not cause symptoms until they become quite large and start pressing on nearby organs. Symptoms of abdominal or chest sarcomas can include pain and difficulty breathing. These symptoms can be caused by other conditions, as well. 

Bone Sarcoma Symptoms 

Early symptoms of bone sarcoma include pain and swelling that comes and goes at first in the area of the tumor. Advanced bone cancer can result in a fracture (break) in the bone where the tumor is located.
