• Chondrosarcoma

    (Cartilage Cancer; Cancer of the Cartilage)

    Definition

    Chondrosarcoma is a type of cancer. It grows in cartilage cells in the body. Cartilage is the connective tissue. Most bones are created from cartilage.
    This cancer is typically found in the cartilage cells of the femur, arm, pelvis, knee, and spine. Rarely, the ribs and other areas may also be affected.
    Cancer occurs when cells in the body divide without control or order. If cells keep dividing uncontrollably, a mass of tissue forms. This is called a growth or tumor. The term cancer refers to malignant tumors. They can invade nearby tissue and spread to other parts of the body.
