Symptoms of Sarcoma

The first symptom of sarcoma is usually a painless lump. As the tumor grows and begins to press against nearby nerves and muscles, pain or soreness can occur. Symptoms become more noticeable when the cancer reaches advanced stages. In some cases, individuals don't experience any symptoms until the advanced stages of the cancer. Because soft tissue is very elastic, the tumors can grow quite large before they are felt. Common symptoms of sarcoma include:

  • A lump on the body, usually painless, but may cause discomfort depending on its location
  • Stomach pain
  • Vomiting
  • Blood in the stool (a red or tar-like black stool)
  • A feeling of fullness after not eating very much
  • Lack of appetite or unexplained weight loss

The symptoms of osteosarcoma and Ewing sarcoma depend on the size and location of the tumor. Common symptoms of these cancers include:

  • Pain in the affected bone
  • Swelling or a lump in the area of the tumor, which may feel warm
  • Occasionally, a fracture in the affected bone
  • Fever
  • Tiredness
  • Weakness
  • Unexplained weight loss

These symptoms could be associated with other conditions. Talk to your physician if you experience any of these symptoms.
