<s>[INST] my granddaughter is 21 months old. just had rhabdomyosarcoma tumor was really rapid growing. had on uterus, phil.tube and ovary. was removed about wk ago. Now dr says they discovered duplex kidney on one side with the two ureters total. Said now they want to possibly remove the partial kidney and one ureter. Thinks possible was clipped during removal of the rhabdomyosarcoma. It was wrapped around the ureter but didn t say attached to it. She has responded well from the tumor surg. and chemo so far. Is still off the chemo recooperating from the surg. What I want to know is there a large chance the cancer was on that ureter too and should it of been removed as a precaution? [/INST] Hi, Its very unfortunate that your granddaughter had rhabdomyosarcoma. Rhabdomyosarcoma is a soft tissue tumor which usually arises from muscles which are attached to bones. It's very unlikely that it arises from the ureter. The tumor can encompass the ureter and may compress, which needs to be corrected. I would advise you to follow up with your pediatric surgeon or urologist advice. Hope I have answered your query. Let me know if I can assist you further.  </s>
