Disease: Liposarcoma


    Liposarcoma is a rare type of cancer that begins in the fat cells. Liposarcoma is considered a type of soft tissue sarcoma.

    Liposarcoma can occur in fat cells in any part of the body, but most cases occur in the muscles of the limbs or in the abdomen. Liposarcoma occurs most often in older adults, though it can occur at any age.

    Treatment for liposarcoma typically involves surgery to remove the cancer. Other treatments, such as radiation therapy, also may be used.

    Liposarcoma signs and symptoms vary depending on the part of the body where the cancer forms.

    Liposarcoma that forms in the arms and legs can cause:

    • A growing lump of tissue under your skin
    • Pain
    • Swelling
    • Weakness of the affected limb

    Liposarcoma that forms in the abdomen can cause:

    • Abdominal pain
    • Abdominal swelling
    • Feeling full sooner when eating
    • Constipation
    • Blood in stool

    When to see a doctor

    Make an appointment with your doctor if you have any persistent signs or symptoms that worry you.

    It's not clear what causes liposarcoma.

    Doctors know that liposarcoma forms when a fat cell develops errors (mutations) in its genetic code. The mutations tell the cell to multiply rapidly and to go on living when other cells would die. The accumulating abnormal cells form a mass (tumor).

    Several types of liposarcoma exist. Some grow slowly and the cells stay in one area of the body. Other types grow very quickly and may spread to other areas of the body.

    Tests and procedures used in liposarcoma diagnosis include:

    • Imaging tests. Your doctor may recommend imaging tests to determine the size and extent of your liposarcoma. Tests may include X-ray, CT scan and MRI.
    • Removing a sample of tissue for testing. During a biopsy procedure, your doctor removes a small sample of tissue to test for cancer cells. Your tumor's location determines how the tissue sample is removed.
    • Using advanced lab tests to determine the kinds of cells involved in the cancer. Doctors who specialize in analyzing blood and body tissue (pathologists) will study your biopsy samples using specialized laboratory tests, such as immunohistochemistry, cytogenetic analysis, fluorescence in situ hybridization and molecular genetic testing. These tests provide information about your liposarcoma that helps your doctor determine your prognosis and your treatment options.
