In China, a 10-year-old boy donated blood 30 times and underwent surgery to save his mother from cancer.

In Anhui Province, ten-year-old Cao Xuanyi donated bone marrow to his mother, who was ill with leukemia. The boy donated blood 30 times for doctors to check his tissue compatibility, and then underwent seven injections of the drug to mobilize blood stem cells. The boy is the only member of a large family who could become a donor. The child has been preparing for the operation since spring. After the transplant, doctors will continue to work with Xuanyi's mother to restore her body's ability to produce blood cells.
