2024年12月20日 · Chronic lymphocytic leukemia (CLL) is a type of cancer of the blood and bone marrow — the spongy tissue inside bones where blood cells are made. The term "chronic" in chronic lymphocytic leukemia comes from the fact that this leukemia typically progresses more slowly than other types of leukemia.

Lymphoid leukemias are a group of leukemias affecting circulating lymphocytes, a type of white blood cell. The lymphocytic leukemias are closely related to lymphomas of the lymphocytes, to the point that some of them are unitary disease entities that can be called by either name (for example, adult T-cell leukemia/lymphoma).

2024年12月20日 · Acute lymphocytic leukemia is the most common type of cancer in children, and treatments result in a good chance for a cure. Acute lymphocytic leukemia can also occur in adults, though the chance of a cure is greatly reduced.

Chronic lymphocytic leukemia (CLL) is one the most common types of leukemia in adults. It's a type of cancer that starts in early forms of certain white blood cells (called lymphocytes) in the bone marrow.

2024年12月20日 · Chronic lymphocytic leukemia is typically a slow-growing cancer that may not require treatment. While some people may refer to this as a "good" type of cancer, it doesn't really make receiving a cancer diagnosis any easier.

2023年8月26日 · Acute lymphocytic leukemia (ALL) is a malignancy of B or T lymphoblasts characterized by uncontrolled proliferation of abnormal, immature lymphocytes and their progenitors, which ultimately leads to the replacement of bone marrow elements and other lymphoid organs resulting in a typical disease pattern characteristic of acute lymphocytic …

Acute lymphocytic leukemia (ALL) is also called acute lymphoblastic leukemia. “Acute” means that the leukemia can progress quickly, and if not treated, would probably be fatal within a few months. "Lymphocytic" means it develops from early (immature) forms of …

2024年10月15日 · Chronic lymphocytic leukemia (CLL) is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell). Leukemia may affect red blood cells, white blood cells, and platelets. Signs and symptoms of CLL include swollen lymph nodes and feeling tired. Tests that examine the blood are used to diagnose CLL.

2022年5月18日 · Myeloid cells develop into red blood cells, platelets and certain types of white blood cells (basophils, eosinophils and neutrophils). Lymphoid cells develop into certain white blood cells (lymphocytes and natural killer cells). However, if you have leukemia, one of the developing blood cells begins to multiply out of control.

2023年1月31日 · Chronic lymphocytic leukemia (CLL) is a type of blood cancer. It’s the most common form of leukemia in adults. It happens when healthy white blood cells (lymphocytes) in your bone marrow mutate, or change, into cancerous cells that multiply and crowd out healthy blood cells and platelets.
