Malignant and Benign Tumors of the Soft Tissue
Tumors can form when cells divide and a mass of abnormal cells binds together. Tumors of the soft tissue are more common than bone tumors and can grow almost anywhere in the body –between blood vessels, ligaments, nerves and muscles.
Malignant, or cancerous, soft tissue tumors are known as sarcomas. Sarcomas are rare and make up only about 1% of all cancerous tumors. Types of malignant soft tissue tumors include:
- Ewing's sarcoma
- Malignant fibrous histiocytoma (MFH)
- Synovial sarcoma
One-third of all soft tissue tumors will be benign, or non-cancerous, and are primarily made of fat. They often occur just beneath the skin as a soft, painless mass, which grows slowly over months or years. Common benign soft tissue tumors include:
- Fibrous histiocytoma
Symptoms, Diagnosis and Outlook
Signs and symptoms of a soft tissue tumor, include:
- A new or growing lump anywhere on your body
- Abdominal pain
- Blood in your stool
- Unusual swelling in arms or legs
To diagnose soft tissue tumors, the experts at Penn State Health may use several types of imaging technology including magnetic resonance imaging (MRI). Other tests include:
- Image guided biopsy may to analyze bone tissue
- Urine test
Your outlook will depend on the size and location of the tumor. Early diagnosis of a tumor is especially important if it is malignant. The earlier the cancer is found, you may have more treatment options available and clinical trials can expand your treatment options.
