Rhabdomyosarcoma begins in the soft tissues in a type of muscle called striated muscle.
It can occur anywhere in the body. There are several types of sarcoma that are found in children and young adults. The cancer cells must be looked at under a microscope to tell which type of sarcoma it is. Rhabdomyosarcoma is the most common type of sarcoma found in the soft tissues of children. If your child has symptoms of a sarcoma, your child's doctor may order x-rays and other tests.
