Are there effective natural treatments for childhood leukemia?

Unfortunately, no. No natural treatments have been proven to cure this. Treatment of childhood leukemia requires chemotherapy and sometimes radiation therapy and stem cell transplantation.Working with an experienced pediatric oncologist is a must!
In addition to Rx. Childhood leukemia has such a good remission rate due to chemotherapy drugs. These should be used because they work. In addition many families find prayer, meditation, sleep, nutrition, and other complementary treatments helpful. These should not replace the treatments that have been tested and work well ~ there's a 90% remission rate for some types of childhood leukemia!
Short answer is no, . Many antitumor agents are derived from natural plant and microorganism material.
