Every day, your bone marrow makes billions of new blood cells, and most of them are red cells. When you have leukemia, your body makes more white cells than it needs. These leukemia cells can’t fight infection the way normal white blood cells do. And because there are so many of them...
Leukemiais amalignancy(cancer) of blood cells. In leukemia, abnormal blood cells are produced in the bone marrow. Usually, leukemia involves the production of abnormal white blood cells -- the cells responsible for fighting infection. However, the abnormal cells in leukemia do not function in the...
Leukemia is a type of cancer that attacks the body's bone marrow and other blood-producing tissues and limits the immune system's potential to fight off infection. Learn about the signs and symptoms of leukemia, such as fever, weakness, and fatigue, and explore treatments, including radiation ...
Lymphocytes help your body fight infection. They're made in the soft center of your bones, called the marrow. If you have CLL, your body makes an abnormally high number of lymphocytes that aren't working right. More adults get CLL than any other type of leukemia. It usually grows slowly...
There are two main types of chronic leukemia:Chronic lymphocytic leukemia (CLL) is rare in people under age 30. It is more likely to develop as a person ages. Most cases occur in people between ages 60 and 70. In CLL, abnormal lymphocytes cannot fight infection as well as normal cells ...
Lymphocytes become a type of white blood cell, which helps your body fight off infections. But with CLL, the lymphocytes grow out of control. Blood tests often show a high white blood cell or lymphocyte level. You'd get more tests to find out if this is leukemia. ...
Acute lymphocytic leukemia (ALL) andchronic lymphocytic leukemia (CLL)affect thelymphocytic WBCs(B cells and T cells). Acute myeloid leukemia (AML) andchronic myeloid leukemia (CML)affectmyeloid cells, which are precursors of red blood cells (RBCs),platelets, and all other WBCs besides lymphocyte...
What are the differences between acute lymphoblastic leukemia (ALL) and chronic lymphocytic leukemia (CLL)? For each type of leukemia, explain how it originates and the key signs and symptoms. List six proposed etiologic factors of cancer and give examples of each.Explore...
Petechiae leukemia Often referred to as "leukemia spots," these petechiae are a symptom of leukemia. This form of cancer causes your bone marrow to produce large numbers of abnormal white blood cells, which eventually overwhelm your normal blood cells. This makes you more prone to infection. Le...
: Cancer that starts in blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood -- "leukemia," lymphoblastic leukemia (ALL and CLL), myelogenous leukemia (AML and CML), T-cell leukemia, and hairy-cell leukemia...
