Philadelphia, P.A. - What's being called a potential medical breakthrough could help young patients suffering from Leukemia.
Researchers found that a genetically engineered cell therapy used for adults seems to be working well for children too.
Doctors take immune system cells from the patient, add a gene that attacks cancer, and put the cells with the gene back into the patient.
It's already being credited with wiping out one girl's cancer within a couple of weeks.
The process needs to be studied further, but researchers hope it will eventually take the place of bone marrow transplants.
