What Is Childhood Rhabdomyosarcoma?

  • Rhabdomyosarcoma is a cancerous tumor that grows in the body's soft tissues (which connect, support or surround organs and other body structures), particularly in the muscles that attach to bone and help the body to move. Just weeks into the life of a developing embryo, rhabdomyoblast cells (which grow into muscle over time) begin to form. These are the cells that can develop into rhabdomyosarcoma.

    • Because this is a cancer of embryonal cells, it is much more common in children, although it can occur in adults.
    • Rhabdomyosarcomas are most often located in the head, neck, bladder, vagina, arms, legs and trunk.
    • These tumors can also be found in places where skeletal muscles are absent or very small, such as the prostate, middle ear or bile duct system.
