The primary difference between leukemia and chronic lymphocytic leukemia (CLL) is the type of cells that are affected. Leukemia is a type of cancer that affects the blood and bone marrow, where immature white blood cells, called blasts, rapidly multiply. This can cause anemia, bleeding, and infections. CLL, on the other hand, is a type of leukemia that affects mature white blood cells, called lymphocytes. The rapid multiplication of lymphocytes can cause an enlarged spleen, swollen lymph nodes, and fatigue.
Leukemia is a broad term that encompasses several different types of cancer, including acute myeloid leukemia, acute lymphoblastic leukemia, and chronic myeloid leukemia. CLL is the most common type of leukemia in adults, and it is considered a "slow-growing" cancer. This means that the symptoms of CLL may not appear for many years, and it may take a long time for the cancer to progress.
Another major difference between leukemia and CLL is the treatment options. Leukemia is generally treated with chemotherapy, radiation, and/or stem cell transplant. CLL, however, is usually treated with medications such as rituximab and ibrutinib, which can help slow down the progression of the disease. In some cases, CLL can be managed with watchful waiting.
In summary, the main difference between leukemia and chronic lymphocytic leukemia is the type of cells that are affected and the treatment options available. Leukemia affects immature white blood cells, while CLL affects mature white blood cells. Treatment options for leukemia include chemotherapy, radiation, and stem cell transplant, while CLL is usually managed with medications and watchful waiting.
