Rhabdomyosarcoma (RMS or "rhabdo") is a cancerous tumor that develops in the body's soft tissues, usually the muscles. It can affect the head, neck, bladder, vagina, arms, legs, trunk, or just about any body part. Cells from rhabdomyosarcomas are often fast growing and can spread (metastasize) to other parts of the body.
Rhabdomyosarcoma (rab-doe-myo-sar-KO-muh) is the most common type of soft-tissue cancer in children. Kids can develop it at any age, but most cases are in kids between 2 and 6 years old and 15 and 19 years old. Boys tend to be affected more often than girls.
Treating RMS usually includes chemotherapy, surgery, and radiation. With early detection and timely treatment, most kids make a full recovery.
