Prayers please

I feel like I keep on writing about negative things, my next entry will be, PROMISE! I just wanted to ask for prayers for my cousin. Last year around June she went into the hospital to have her second little boy and they saw that some of her blood work came back abnormal. She was diagnosed with Acute Leukemia. After she had her little boy she went through chemotherapy and everything for a few months. They found out at the beginning of the year that her brother was a 100% match and the process of having a bone marrow transplant. Well she had the transplant about two months ago and after hanging out in the hospital for about a month afterwards she was allowed to come home. They told her that she was leukemia free. Well yesterday she was feeling weak and so she went to the hospital this morning. They found out that she has 7% blast cells (these cells are premature blood cells that have not differentiated or turned into a more specific cell) and so she was readmitted to the hospital because the leukemia is back. If this doesn't make sense this may help a little bit
Acute versus Chronic Leukemia

The blood-forming (hematopoietic) cells of acute leukemia remain in an immature state, so they reproduce and accumulate very rapidly. Therefore, acute leukemia needs to be treated immediately, otherwise the disease may be fatal within a few months. Fortunately, some subtypes of acute leukemia respond very well to available therapies and they are curable. Children often develop acute forms of leukemia, which are managed differently from leukemia in adults.
