Most people don’t have sarcoma symptoms or signs early on. Because of this, sarcoma is usually difficult to detect in the early stages.

When signs or symptoms do occur, they can be very different from person to person. For example, someone with a sarcoma lump in their leg might feel leg pain. Another person might have difficulty moving a joint if a sarcoma lump is growing in that area. Feeling generally unwell or having a fever are also sarcoma symptoms.

As the disease becomes more advanced, more problems usually occur. This is especially true as the sarcoma lump grows and presses on nearby nerves, organs or muscles. This can cause symptoms of pain, a feeling of fullness or issues with breathing.

Take Charge of Your Health

Talk to your primary care provider if you have symptoms that you think may be sarcoma. UW Medicine Primary Care can help you get started. Learn about Fred Hutch's relationship with UW Medicine.

Sarcoma Symptoms

For people who do notice symptoms, they may include a:

  • Painless sarcoma lump or swelling (an early sign)
  • Limited range of motion in a joint
  • Fever with an unknown cause
  • Bone that breaks for no clear reason
  • Lump that is becoming bigger or painful

What to Do if You Have Symptoms or Signs

If you notice any of these symptoms or signs, let your primary care provider (PCP) know. Be aware that your symptoms may not be related to sarcoma. Instead they may be signs of a different health problem. Always check with a provider if you have any concerns or changes in your health.


Sarcoma Symptoms and Signs FAQ

About half of soft tissue sarcoma patients are diagnosed around four months after they recognize a possible symptom. An additional 20% of sarcoma patients are diagnosed after six months.

Diagnosing sarcoma is not a one-time event, but a process. It involves having a physical exam, imaging tests and having a biopsy.

A soft tissue sarcoma can look like a rounded mass under the skin. Depending on the type of sarcoma a patient has and where it is located, the lump can vary in size and texture. Additionally, if it’s growing close to the skin’s surface, it can be discolored and cause the skin to pucker or dimple.
