Facebook seems to be emerging more than just a popular social networking website -- it has helped save a four-year-old boy suffering from leukaemia.

The boy was reportedly diagnosed with the blood cancer after his worried father put a photo of him on Facebook. Anaesthetic assistant Philip Rice noticed rash all over his son Ted's body as he put him to bed. He took a photo and put it on the social networking site. Within minutes a doctor friend recognised the rash as a symptom of acute lymphocytic leukaemia and urged him to take Ted to hospital immediately, the Daily Express reported.
