Can a family history be a reason for Acute Lymphoblastic Leukemia in an infant?
Siblings of children with leukemia, including ALL, are 2 to 4 times more at risk of developing the disease. The identical twin of a child with leukemia has a 25% greater risk of developing the condition as well. This risk is highest at birth, and decreases up until the age of 7. After that age, the unaffected twin has the same risk as an unrelated child.
