Rhabdomyoma is a benign (noncancerous) tumor that originates in MUSCLE tissue, usually skeletal muscle.Rhabdomyoma is somewhat more common in children than adults. The doctor may choose to surgically remove the rhabdomyoma to obtain a definitive diagnosis and rule out cancer. However, rhabdomyoma does not become cancerous. Rather, it may have the appearance of a cancerous tumor so the doctor removes it for biopsy and laboratory analysis. Rhabdomyoma may occur in the HEART, presenting a potentially life-threatening situation that usually requires surgery to remove the tumor.
