5 year old diagnosed with leukemia

Hey everyone. My 5 year old cousin joao who lives in Portugal was recently diagnosed with leukemia. His family is from the Azores. He was flown to Lisbon as an emergency and will be there for a couple of months while he receives treatment . My family in Portugal is pretty poor. They barely have enough money for food on a regular basis. Any donation would help. Nothing is to small . Thank you
