In this article, we will discuss Chronic Lymphocytic Leukemia (1). So, let’s get started.
Chronic Lymphocytic Leukemia (CLL) is a type of cancer that affects the blood and bone marrow.
Definition:
CLL is a slow-growing leukemia that primarily affects a type of white blood cell called lymphocytes. It is characterized by the accumulation of abnormal lymphocytes in the blood and bone marrow.
Incidence:
CLL is the most common type of leukemia in adults. It typically occurs in older individuals, with the average age at diagnosis being around 70 years.
Cell Type:
CLL primarily involves B lymphocytes, a type of white blood cell responsible for producing antibodies. The abnormal B cells accumulate and crowd out normal blood cells in the bone marrow.
Symptoms:
In the early stages, CLL may not cause noticeable symptoms. As the disease progresses, symptoms may include fatigue, enlarged lymph nodes, unintentional weight loss, night sweats, and frequent infections.
Diagnosis:
Diagnosis is typically made through blood tests that reveal an elevated number of lymphocytes. Additional tests, such as bone marrow biopsy, flow cytometry, and imaging studies, may be conducted for confirmation.
