Do a lot of people die from Acute Lymphoblastic Leukemia
Medicine has come a long way in treating this particular cancer. Although the treatments may seem debilitating, it is highly curable. Especially 13 year olds who have previously been healthy.
Depends on what you consider "a lot," but yes it can be fatal. However, survival rate is about 80% or better - depending on age.http://leukemia.emedtv.com/acute-lymphocytic-leukemia/acute-lymphocytic-leukemia-statistics.html
