It,s true we don,t know the full story , but I do know that postponing NHS treatments can result in long delays , this could make a difference , treatment for a child with cancer , must come before any holiday and to think there is some reason to justify the parents actions is strange , speaking as a parent , when my children were born I happily put thier happiness , health and welfare before any thing else on this earth ,POTPONE THE STUPID HOLIDAY , get the child treated .
