It could be another couple of weeks before nine month old Treyden Kurtzweil can receive a potentially life saving stem cell transplant. Treyden is currently undergoing another round of chemotherapy at Ministry St. Joseph's in Marshfield after his parents learned just last week that his leukemia is back. On Monday doctors will test Treyden's white cell count again. If the count is zero they will take him off the chemo and, once it's out of his system, transport him to Madison for the stem cell transplant.
