What are the names of the different leukemias?
The main types of leukemia are classified into four primary categories: acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), and chronic myeloid leukemia (CML). Acute leukemias, such as ALL and AML, progress rapidly, while chronic leukemias, including CLL and CML, typically develop more slowly. Each type has distinct characteristics, treatment approaches, and prognoses.
How many different kinds of leukemia are there?
Chronic and Acute. Chronic worsens slowly, acute worsens quickly. Chronic leukemias are Chronic Lymphoblasitc Leukemia andChronic Myeloid Leukemia. Acute leukemias are Acute Lymphoblastice Leukemia and Acute Myeloid Leukemia.
What does chronic myeloid leukemia affect?
Chronic Myeloid Leukemia affects genes in the blood cells. Abnormal chromosomes develop and create new genes, these genes allow diseased blood cells to survive. You can learn more about Chronic Myeloid Leukemia at the Mayo Clinic website.
How does chronic lymphocytic leukemia affect your kidneys?
There are four major types of leukemia:AcuteChronicLymphocyticMyeloid -In acute leukemia, the bone marrow cells don't mature properly. These immature cells continue to reproduce and crowd out normal cells. Some types of acute leukemia respond well to treatment and many patients are cured. Other types have a less favorable outlook. In chronic leukemia the cells look mature, but they are not really normal and they can't fight infection they way they should. Also, the cells live too long, build up, and crowd out normal bone marrow cells.Lymphocytic and myeloid (or myelogenous) refer to the different cell types from which leukemias start. Lymphocytic leukemias develop from lymphocytes in the bone marrow. Myeloid leukemia mainly develops from other types of white blood cells such as granulocytes or monocytes.Because leukemia does not usually form tumors, imaging tests are not always helpful. Imaging studies might be done in people with ALL, but they are done more often to look for infections or other problems rather than for the leukemia.

What is Acute Lymphoblast Leukemia?
What Is Acute Lymphocytic Leukemia (ALL)?Acute lymphocytic leukemia (ALL), also called acute lymphoblastic leukemia, is a cancer that starts from white blood cells called lymphocytes in the bone marrow (the soft inner part of the bones, where new blood cells are made).In most cases, the leukemia invades the blood fairly quickly. It can then spread to other parts of the body, including the lymph nodes, liver, spleen, central nervous system (brain and spinal cord), and testicles (in males). Other types of cancer that start in these organs and then spread to the bone marrow are not leukemia.The term "acute" means that the leukemia can progress quickly, and if not treated, would probably be fatal in a few months. "Lymphocytic" or "lymphoblastic" means it develops from cells called lymphocytes or lymphoblasts. This is different from acute myeloid leukemia (AML), which develops in other blood cell types found in the bone marrow. For more information on AML, see our document, Leukemia--Acute Myeloid.Other types of cancer that start in lymphocytes are known as lymphomas (non-Hodgkin lymphoma or Hodgkin disease). The main difference between these types of cancers is that ALL starts in the bone marrow and may spread to other places, while lymphomas start in lymph nodes or other organs and then may spread to the bone marrow. Sometimes cancerous lymphocytes are found in both the bone marrow and lymph nodes when the cancer is first diagnosed, which can make it hard to tell if the cancer is a leukemia or a lymphoma. If more than 25% of the bone marrow is replaced by cancerous lymphocytes, the disease is usually considered to be a leukemia. The size of lymph nodes is also important. The bigger they are, the more likely the disease is a lymphoma. For more information on lymphomas, see our documents, Non-Hodgkin Lymphoma and Hodgkin Disease.Normal bone marrow, blood, and lymphoid tissueIn order to understand the different types of leukemia, it helps to know about the blood and lymph systems.Bone marrowBone marrow is the soft inner part of some bones, such as the skull, shoulder blades, ribs, pelvis, and backbones. The bone marrow is made up of a small number of blood stem cells, more mature blood-forming cells, fat cells, and supporting tissues that help cells grow.Blood stem cells go through a series of changes to make new blood cells. During this process, the cells develop into either lymphocytes (a kind of white blood cell) or other blood-forming cells. The blood-forming cells can develop into 1 of the 3 main types of blood cell components:red blood cellswhite blood cells (other than lymphocytes)plateletsRed blood cellsRed blood cells carry oxygen from the lungs to all other tissues in the body, and take carbon dioxide back to the lungs to be removed. Anemia (having too few red blood cells in the body) typically causes a person to feel tired, weak, and short of breath because the body tissues are not getting enough oxygen.PlateletsPlatelets are actually cell fragments made by a type of bone marrow cell called the megakaryocyte. Platelets are important in plugging up holes in blood vessels caused by cuts or bruises. A shortage of platelets is called thrombocytopenia. A person with thrombocytopenia may bleed and bruise easily.White blood cellsWhite blood cells help the body fight infections. Lymphocytes are one type of white blood cell. The other types of white blood cells are granulocytes (neutrophils, basophils, and eosinophils) and monocytes.Lymphocytes: These are the main cells that make up lymphoid tissue, a major part of the immune system. Lymphoid tissue is found in lymph nodes, the thymus gland, the spleen, the tonsils and adenoids, and is scattered throughout the digestive and respiratory systems and the bone marrow.Lymphocytes develop from cells called lymphoblasts to become mature, infection-fighting cells. The 2 main types of lymphocytes are B lymphocytes (B cells) and T lymphocytes (T cells).B lymphocytes: B lymphocytes protect the body from invading germs by developing (maturing) into plasma cells, which make proteins called antibodies. The antibodies attach to the germs (bacteria, viruses, and fungi), which helps other white blood cells called granulocytes to recognize and destroy them.T lymphocytes: T lymphocytes can recognize cells infected by viruses and directly destroy these cells.Granulocytes: These are white blood cells that have granules in them, which are spots that can be seen under the microscope. These granules contain enzymes and other substances that can destroy germs, such as bacteria. The 3 types of granulocytes -- neutrophils, basophils, andeosinophils -- are distinguished by the size and color of their granules. Granulocytes develop from blood-forming cells called myeloblasts to become mature, infection-fighting cells.Monocytes: These white blood cells, which are related to granulocytes, also help protect the body against bacteria. They start in the bone marrow as blood-forming monoblastsand develop into mature monocytes. After circulating in the bloodstream for about a day, monocytes enter body tissues to become macrophages, which can destroy some germs by surrounding and digesting them. Macrophages also help lymphocytes recognize germs and start making antibodies to fight them.Any of the blood-forming or lymphoid cells from the bone marrow can turn into a leukemia cell. Once this change takes place, the leukemia cells fail to go through their normal process of maturing. Leukemia cells may reproduce quickly, but in most cases they don't die when they should. They survive and build up in the bone marrow. Over time, these cells spill into the bloodstream and spread to other organs, where they can keep other cells in the body from functioning normally.Types of leukemiaNot all leukemias are the same. Leukemias are divided into 4 main types. Knowing the specific type of leukemia helps doctors better predict each patient's prognosis (outlook) and select the best treatment.Acute leukemia versus chronic leukemiaThe first factor in classifying a patient's leukemia is whether most of the abnormal cells are mature (look like normal white blood cells) or immature (look more like stem cells).Acute leukemia: In acute leukemia, the bone marrow cells cannot mature properly. Immature leukemia cells continue to reproduce and build up. Without treatment, most patients with acute leukemia would live only a few months. Some types of acute leukemia respond well to treatment, and many patients can be cured. Other types of acute leukemia have a less favorable outlook.Chronic leukemia: In chronic leukemia, the cells can mature partly but not completely. These cells may look fairly normal, but they are not. They generally do not fight infection as well as do normal white blood cells. And they survive longer, build up, and crowd out normal cells. Chronic leukemias tend to progress over a longer period of time, and most patients can live for many years. But chronic leukemias are generally harder to cure than acute leukemias.Myeloid leukemia versus lymphocytic leukemiaThe second factor in classifying leukemia is the type of bone marrow cells that are affected.Myeloid leukemia: Leukemias that start in early forms of myeloid cells -- white blood cells (other than lymphocytes), red blood cells, or platelet-making cells (megakaryocytes) -- aremyeloid leukemias (also known as myelocytic, myelogenous, or non-lymphocytic leukemias).Lymphocytic leukemia: If the cancer starts in early forms of lymphocytes, it is called lymphocytic leukemia (also known aslymphoid or lymphoblastic leukemia). Lymphomas are also cancers that start in lymphocytes. Lymphocytic leukemias develop from cells in the bone marrow, but lymphomas develop from cells in lymph nodes or other organs.Leukemias can be divided into 4 main types based on whether they are acute or chronic, and whether they are myeloid or lymphocytic. The 4 main types are:acute myeloid (or myelogenous) leukemia (AML)chronic myeloid (or myelogenous) leukemia (CML)acute lymphocytic (or lymphoblastic) leukemia (ALL)chronic lymphocytic leukemia (CLL)ALL is the most common of the 4 major types of leukemia among children, but it is actually the least common type among adults.
What is the difference between acute myeloid leukemia and acute monocytic leukemia?
Acute leukemias develop and progress rapidly, while chronic leukemias develop slowly and have a better prognosis. If someone was diagnoed with leukemia, the blood smear and other tests can indicate if this patient have chronic or acute leukemia.
Chronic diseases develop slowly?
Yes, they develop over time and not abruptly.
Why does anemia or thrombocytopenia develop in patients with leukemia?
Hematopoiesis occurs in the bone marrow. Leukemia is a kind of blood or bone marrow cancer which disrupts regular function and production of blood cells. A person with leukemia can not produce regular, healthy blood cells and that's why this person develop anemia.
Does Hairy cell leukemia develop more in men?
Men are four times more likely to develop HCL than women
How many people are diagnosed with Leukemia in the U.S. every year?
53,000 people are diagnosed with lymphoma every year. of those 53,000, only 15% are diagnosed with non-hodgkin's t-cell lymphoma. of that 15%, only 5% are children and of all children diagnosed with non-hodgkin's t-cell lymphoma, 70% are male. despite those odds, my sister was diagnosed with it in 2001, she was 7 years old. i got this here: In the US, childhood Non-Hodgkin's lymphomas make up about 5% of the 53,370 cases of NHL diagnosed each year. http://www.lymphomainfo.net/childhood/nhl.html About 70% of non-Hodgkin lymphoma occurs in boys, and it is about 40% more common in white children than black children. http://www.cancer.org/docroot/CRI/content/CRI_2_4_1x_What_are_the_key_statistics_for_childhood_non_Hodgkins_lymphoma_9.asp Non-Hodgkin's Lymphomas caused by malignant (cancerous) T-Cell lymphocytes represent a smaller subset (about 15% in the US) of the known types of lymphoma… http://www.lymphomainfo.net/nhl/t-cell.html 119 female children in the US per year .00225% chances for female children (please correct math if wrong, 119/53000)
