• Chronic Lymphocytic Leukemia (CLL) is often a slow growing cancer that can remain indolent for years.

• However, the overproduction of lymphocytes can worsen over time and cause an increase in symptoms and issues. 

• Identifying the genetic changes can be useful for stratifying risk and understanding the disease state.
