I had a kidney cancer when i was kid , im asking about the chances that any kind of cancer could come back again anywhere else to me in the long run ?

More info needed: Most likely you had Wilms tumor ( neuroblastoma ) detected at a early stage most likely you are cured . Unfortunately you are at a higher risk than people who never had malignant disease best management for you see your oncologist for regular follow up , and keep up with remarkable progress in treatment of malignant diseases best cures are ahead , do not get disheartened .Good Luck
