CHICAGO (WLS) -- Blanca Magallon, a Chicago police officer and mother of four who is fighting leukemia, underwent a bone marrow transplant on Wednesday.
Magallon's family says the procedure went well. Doctors told her that without a transplant, her prognosis was bleak.
Her doctors say the next few days are critical to see how her body responds.
