What is Chronic lymphocytic leukemia (CLL)

Chronic lymphocytic leukemia (CLL) is a type of cancer that affects the blood and bone marrow. It is characterized by the overproduction of abnormal white blood cells called lymphocytes. These cells accumulate in the bone marrow, lymph nodes, and other organs, interfering with the production of healthy blood cells.

CLL is a slow-growing cancer that primarily affects older adults, with the average age of diagnosis being around 70 years. It often develops gradually and may not cause noticeable symptoms in the early stages. As the disease progresses, individuals may experience fatigue, enlarged lymph nodes, weight loss, frequent infections, and anemia.

While the exact cause of CLL is unknown, certain risk factors such as family history, exposure to certain chemicals, and certain genetic abnormalities may increase the likelihood of developing the disease. Diagnosis typically involves blood tests, bone marrow biopsy, and imaging studies.

Treatment for CLL depends on various factors including the stage of the disease, overall health, and individual preferences. Options may include watchful waiting, chemotherapy, targeted therapy, immunotherapy, and stem cell transplant. Regular monitoring and follow-up care are essential to manage the disease effectively.
