Signs & Symptoms

Soft tissue sarcoma may not cause any signs or symptoms in its early stages. These will generally appear as the tumour grows and begins to press on nerves, muscles, and other structures. However, it is important to note that other health conditions can cause the same symptoms as soft tissue sarcoma.

The signs and symptoms of soft tissue sarcoma will vary depending on where the tumour starts in the body:

  • Arm, leg, trunk, head and neck:
    • Lump or swelling
    • Tenderness or pain
  • Abdomen:
    • Feeling of fullness
    • Pain in abdomen or back
  • Gastrointestinal tract:
    • Nausea and vomiting
    • Diarrhea
    • Constipation
    • Blood in the stool
    • Abdominal pain
  • Other:
    • Abnormal vaginal bleeding
    • Pelvic pain
    • Difficulty breathing
    • Lymphedema
    • Abnormal bumps or patches on the skin
