Good. : This disease is curable in 80% of cases. There are many findings of the leukemia that can effect the prognosis. Some findings make the curability higher, some make it lower. Overall, there are good treatments for this disease.

>80%: While there are many variables that determine the answer to that exactly - things such as type of ALL, CNS involvement, etc - the prognosis for ALL is greater than 80% now. Some types even exceed 90%. A lot also depends on early recognition and level of care. It's a must that well trained and up-to-date pediatric oncologists are treating.
