Rhabdomyosarcoma (RMS) is a type of cancer that develops from cells that normally evolve into skeletal muscles. Because RMS begins in embryonic cells, it is much more common in children, although it does occur in adults as well. Common sites include the head and neck; urinary and reproductive organs; arms and legs; and trunk. There are two main types of RMS. Both tend to grow quickly and require intensive treatment.
