Zainab Mughal, two, from South Florida, was diagnosed with neuroblastoma, a cancer of the nerve cells, in October
In addition to chemotherapy, Zainab needs blood transfusions to restore blood cells destroyed from treatment
However, she has a rare blood type because she is missing a common antigen, or sugar, known as Indian B
Donors must be 100 percent of Pakistani, Indian or Iranian descent; have blood type A or O; and must also be missing the antigen
This makes less than four percent of the world's population compatible
