Hello doc, my daughter 9-10 yrs has undergone wilms tumor treatment (stage I- single kidney-left) and is under review, and is perfectly active and is going to school. We live in a hot and humid climate and sweat a lot(she has been taking average fluids 3 ltrs/day), during the last review in the scan report it was reported that there were shades of gall stones and the biggest being 0.5cm kindly advise what diet should we follow and what physical activity to do/avoid, and ways to dissolve these suspected gall stones through changes in diet.
Your daughter should continue her present level of activity and eat a well-balanced healthy diet while her doctor determines the reason for the gall stones and whether they need to be removed.  There is no single answer to your question until the reason for the stones is determined.  It may be necessary to have her gall bladder removed if he stones cannot be ad Chat Doctor.  Please consult her doctor with this concern. Meanwhile, do encourage fluid intake as you are now. Treatment for asymptomatic gallstones in the absence of sickle cell disease can include monitoring and possibly use of Ursodeoxycholic acid therapy.  Symptomatic gallstones usually have to be surgically managed.
