Symptoms

A soft tissue sarcoma may not cause any signs and symptoms in its early stages. As the tumor grows, it may cause:

• A noticeable lump or swelling
• Pain, if a tumor presses on nerves or muscles

When to see a doctor

Make an appointment with your doctor if you have:

• A lump that is increasing in size or becomes painful
• A lump of any size that's located deep within a muscle
• Recurrence of a lump that's been removed
