MeSH Leukemia or leukaemia (Greek leukos , "white"; aima , "blood") is a cancer of the blood or bone marrow and is characterized by an abnormal proliferation (production by multiplication) of blood cells , usually white blood cells ( leukocytes ). It is part of the broad group of diseases called hematological neoplasms Contents Classification Comparison of leukemia types Symptoms Causes and risk factors ... edit Classification Leukemia is a broad term covering a spectrum of diseases. Leukemia is cancer in the blood. Leukemia is clinically and pathologically split into its acute and chronic forms. Acute leukemia is characterized by the rapid increase of immature blood cells. This crowding makes the bone marrow unable to produce healthy blood cells. Acute forms of leukemia can occur in children and young adults. (In fact, it is a more common cause of death for children in the US than any other type of malignant disease). Immediate treatment is required in acute leukemias due to the rapid progression and accumulation of the malignant cells, which then spill over into the bloodstream and spread to other organs of the body. Central nervous system (CNS) involvement is uncommon, although the disease can occasionally cause cranial nerve palsies.

It starts in the bone marrow, the soft tissue inside most bones. Bone marrow is where blood cells are made. When you are healthy, your bone marrow makes: White blood cells , which help your body fight infection. Red blood cells , which carry oxygen to all parts of your body. Platelets , which help your blood clot. When you have leukemia, the bone marrow starts to make a lot of abnormal white blood cells, called leukemia cells. They don't do the work of normal white blood cells, they grow faster than normal cells, and they don't stop growing when they should. Over time, leukemia cells can crowd out the normal blood cells. This can lead to serious problems such as

This disease is a very serious, rare type of acute leukemia ( cancer of the white blood cells). I admitted her to our oncology floor in the hospital. A teenager, she had been completely well until one Sunday when she developed unusually heavy menstrual bleeding. She saw her doctor in her small country town on Monday, had a blood count done on Tuesday, and was flown up to us in Perth on Wednesday with a diagnosis of acute (rapid onset) leukemia. The next day, we performed a biopsy of the bone marrow that enabled us to confirm the diagnosis. We immediately started

Authors and Editors Related leukemia articles: Leukemia - on WebMD Leukemia - on MedicineNet Leukemia Overview Cancer is a process of uncontrolled abnormal cell growth and development. Under normal circumstances, cells are formed, mature, carry out their intended function, and then die. New cells are constantly regenerated in the body to replace those cells and to maintain normal cellular function. Cancer represents the disturbance of this process, which can occur in several ways. Cells may grow and reproduce in a disorganized and out-of-control fashion. Cells may fail to develop properly, so they will not function normally. Cells may fail to die normally. One or a combination of these processes may occur when cells become cancerous. Leukemia is a cancer of blood-forming cells in the bone marrow . These deranged, immature cells accumulate in the blood and within organs of the body. They are not able to carry out the normal functions of blood cells.

As leukemia progresses, the cancer interferes with the body's production of other types of blood cells, including red blood cells and platelets. This results in

In acute leukemia , symptoms appear quickly and worsen quickly. This form of leukemia may develop over a short period of days to weeks. Abnormal white blood cells may collect in the brain or spinal cord. The result may be headaches, vomiting, confusion, loss of muscle control and difficulty seeing. Some patients develop sores in the eyes or unusual skin rashes. Leukemia also can affect the lungs and other parts of the body. In chronic leukemia , symptoms may not appear for months or years. Doctors may find chronic leukemia during a routine exam before any symptoms arise. This form of leukemia may develop over longer periods covering months or years before symptoms are apparent. When symptoms do appear, they tend to be mild and worsen gradually. Abnormal white blood cells may gradually collect in various parts of the body, affecting areas such as the skin, central nervous system, digestive tract, kidneys and testicles. The two primary types of childhood leukemia are acute lymphocytic leukemia (ALL) and acute myelogenous leukemia (AML) . These two acute forms of leukemia can develop over a short period of days to weeks. A third chronic form

Swierzewski, III, M.D. Last Reviewed: 04 Dec 2007 Home Leukemia Overview Questions to Ask Your Doctor About Your Cancer (Free Handout) Overview Known as leukocytes, these cells are so plentiful in some patients that the blood actually has a whitish tinge. Under normal circumstances, the blood-forming (hematopoietic) cells of the bone marrow make leukocytes to defend the body against infectious organisms, such as viruses and bacteria. If some leukocytes are damaged and remain in an immature form, they become poor infection fighters that multiply excessively and do not die off as they should. These damaged leukemic cells accumulate and lessen the production of oxygen-carrying red blood cells (erythrocytes), blood-clotting cells (platelets), and normal leukocytes. If untreated, the surplus leukemic cells overwhelm the bone marrow, enter the bloodstream, and eventually invade other parts of the body, such as the lymph nodes, spleen, liver, and central nervous system (brain, spinal cord). In this way, the behavior of leukemia is different than that of other cancers, which usually begin in major organs and ultimately spread to the bone marrow. There are more than a dozen varieties of leukemia, but the following 4 types are the most common:

Treatment Decision Tools Detailed Guide: Leukemia - Children's How is Childhood Leukemia Diagnosed? Signs and Symptoms of Childhood Leukemia Most of the signs and symptoms that children with leukemia develop result from a lack of normal blood cells caused by crowding out of normal blood cell-producing bone marrow by the leukemia cells. A child may complain of shortness of breath, excessive tiredness, or the skin may appear pale because of anemia (a shortage of red blood cells). Infection: A child with leukemia may develop an infection that doesn't respond to antibiotics, have a high fever, and become very sick. This is because of a deficiency of normal white blood cells, particularly mature granuloctyes. Although leukemia is a cancer of white blood cells and children with leukemia may have very high white blood cell counts, the leukemic cells do not protect against infection the way normal white blood cells do. Easy bleeding or bruising: A child with leukemia may bruise easily or have increased bleeding from small cuts and nosebleeds. There may be pinhead-sized red spots on the skin that represent bleeding from tiny blood vessels. This results from poor production of blood platelets, which are important for plugging holes in damaged blood vessels.

Leukemia is a general term for several types of cancers characterized by a proliferation of disorganized white blood cells in the bone marrow. It is thought that leukemia results from the mutation of a single white cell that alters its genetic structure. The cell uncontrollably divides until there are billions of copies of this abnormal cell which infiltrate the bone marrow and bloodstream. Diagnosis of all forms of leukemia is done through some combination of a physical exam, blood tests, analysis of chromosomes, and/or bone marrow biopsy. There are four major types of leukemia, classified by how rapidly the disease progresses and which type of white blood cell is affected. In
