Definition of Rhabdomyosarcoma
Rhabdomyosarcoma: A fast-growing malignancy of muscle that mainly affects children (more than 60 percent of cases are diagnosed before age 10) but can occur at any age. Treatment includes surgery, radiotherapy, chemotherapy, and, most often, a combination of these modes of treatment. The outlook depends on a number of factors, including the original location of the tumor.
