Understanding Chronic Lymphocytic Leukemia (CLL)

TLDRChronic Lymphocytic Leukemia (CLL) is a type of leukemia that primarily affects B lymphocytes. It is most common in patients over 70 years old. CLL is characterized by the excessive proliferation and differentiation of lymphocytes, leading to a high number of mature but incompetent B lymphocytes. This can result in hypo gammaglobulinemia and an increased risk of infections. CLL can also lead to bone marrow crowding, which can cause neutropenia, anemia, and thrombocytopenia. Lymphocytosis is a common feature of CLL, with high levels of lymphocytes in the blood. The exact cause of CLL is unknown but may involve genetic and environmental factors.

Q&A

Who is most at risk for developing CLL?

CLL is most common in patients over 70 years old.

What are the symptoms of CLL?

Common symptoms of CLL include fatigue, weight loss, enlarged lymph nodes, and frequent infections.

How is CLL diagnosed?

CLL is typically diagnosed through a blood test that reveals a high number of lymphocytes.

What is the treatment for CLL?

Treatment for CLL can vary depending on the stage and severity of the disease, but may include chemotherapy, targeted therapy, or stem cell transplant.

Is CLL curable?

While CLL is not considered curable, many patients can live with the disease for years with regular monitoring and appropriate treatment.
