My daughter was 5 years old when she was diagnosed with ALL. That was 5 years ago, and she is going great. The survival rate then was 80-85%, which is extremely high. Her blasts (cancer cells) went to 0% after only two months of treatment, but she endured 2.5 years of treatment total. We chose a very agressive form of chemo, and it worked very well. July 25 we will be celebrating 3 years cancer free. If your cousin is in remission, chances are she'll be fine. Have faith, and continue trusting in God. That's what my daughter always said. Her favorite thing to say was "Nothing is impossible with God", and I guess it's true, since she is a healthy young girl now. All the best to you and your family, especially your cousin. Tell her not to stop treatment even if the blasts are at 0. They can come back if treatment hasn't totally been completed. Good luck to you all.
