Help 3-year-old Fight Metastatic Neuroblastoma

Hello  Friends,
My childhood friend's daughter Gouri Nandha(3yrs) is suffering from severe issue with her legs . She was very active but all of a sudden her legs started to have severe pain and she is unable to walk now. Her parents are very poor and still they tried to provide her with all treatments . Doctors were unable to diagnose the issue first thus they landed up to Amrita multispeciality hospital kochi. There doctor asked them for an immediate chemotherapy that may cause them more than 5lacs.

Her parents are really poor and trying hard to collect money. Any help would be greatly appreciated
