Summary
Leukemia is disease of the white blood cells. White blood cells is the second line of defense of your body. The bone marrow is the sight of blood cell formation. In leukemia, the bone marrow produces abnormal white blood cells. These cells disturb the healthy blood cells, making it hard for blood to do its work.
There are different types of leukemia, including
• Acute lymphocytic leukemia
• Acute myeloid leukemia
• Chronic lymphocytic leukemia
• Chronic myeloid leukemia
Leukemia can develop in two ways either quickly or slowly. For example, chronic leukemia grows slowly. In acute leukemia, the cells have abnormal shape and their number increases rapidly. Adults can get both type; children with leukemia most often have

Many types of leukemia exist. Some forms of leukemia are common in children. Other types of leukemia occur in adults.
Leukemia is mainly the disease of white blood cells. White blood cells are potent infection fighters — they normally grow and divide whenever the body needs them to. But in people with leukemia, the bone marrow produces abnormal white blood cells which have different shape and increase in there number, which don't function properly.
Treatment for leukemia can be complex — depending on the type of leukemia and other factors. But there are strategies and resources that can help to make your treatment successful.
Leukemia symptoms are different from one patient to another, depending on the type of leukemia. Common leukemia signs and symptoms include:
• Fever or chills
• Persistent fatigue, weakness
• Frequent or severe infections
• Losing weight without trying
• Swollen lymph nodes, enlarged liver or spleen
• Easy bleeding or bruising
• Recurrent nosebleeds
• Tiny red spots in your skin (petechiae)
• Excessive sweating, especially at night
• Bone pain or

The first type of classification is by how fast the leukemia progresses:
• Acute leukemia. In acute leukemia, the abnormal blood cells are immature blood cells (blasts). They can't carry out their normal functions, and they proliferate rapidly, so the disease worsens quickly. Acute leukemia requires aggressive, timely treatment.
• Chronic leukemia. There are many types of chronic leukemia's. Some produce too many cells and some cause too few cells to be produced. Chronic leukemia involves more mature blood cells. These blood cells replicate or accumulate more slowly and can function normally for a period of time. Some forms of chronic leukemia initially produce no early symptoms and can go unnoticed or undiagnosed for years.
The second type of classification is by type of white blood cell affected:
• Lymphocytic leukemia. This type of leukemia affects the lymphocytes, which form lymphatic tissue. Lymphatic tissue makes up your immune system.
• Myelogenous leukemia. This type of leukemia affects the myeloid cells. Myeloid cells forms to red blood cells, white blood cells and platelet-producing
When cells in the lymphatic system grow at an abnormal rate, it creates a malignant tumor, Cancer. Hodgkin lymphoma and Non- Hodgkin lymphoma are both cancers that originate in white blood cells, in the lymphatic system. The system is responsible for fighting infection, bacteria, viruses, and removing damaged cells by producing lymphocytes (a type of white blood cell that is important to the immune system; they decide how the immune system will respond to infections or any an familiar organism). The system also communicates with the blood circulatory system by transporting lymph (a clear fluid that carries lymphocytes, waste, and excess fluid from tissues back into the blood system through the thoracic duct.)
Leukemia is another type of cancer it is a malignant progressive disease. Some symptoms of leukemia is people weight loss, frequent infections, and easy bleeding or bruising. Also chills, dizziness, fatigue, fever, nausea, night sweats, weakness, or sweating are also side effect or symptoms of leukemia. Most people have to shave their hair of and some people fight the cancer and win. Leukemia involves abnormal white blood cells these cells responsible for fighting infection. The abnormal cell in leukemia does not function in the same way as normal white blood cells do. The leukemia cells continue to grow and divide, eventually crowding out the normal blood cells. There is over 50,000 cases of leukemia occur yearly in the U.S.
What is Leukemia? Leukemia is a cancer in blood forming cells that are in early stages of development. Most of the time the white blood cells, but some types of leukemia start in other types of blood cells. Blood cells are form in bone marrow. Any of these cells can turn into a leukemia cell, once this happens the cell does not mature like it should. The cell may start to produce rapidly and the mutated cells probably won’t go through apoptosis like they should. These cells build up in the bone marrow and crowd out the healthy cells. Typically, leukemia cells get into the blood stream rather quickly. From the blood stream they can spread to places like lymph nodes, spleen, liver, central nervous system or other organs where the leukemia cells can cause those other cells to function irregularly.
The emphasis on health and fitness has become paramount in our society today in an effort to prevent and combat diseases such as Cancers. Cancers are a group of over 100 diseases that affects every aspect of the human system from skin, to bones, to muscles, to blood. One of the most common blood disorders is Leukemia. As defined by the U.S. National Library of Medicine, Leukemia is a type of blood cancer that begins in the bone marrow. The bone marrow is the soft tissue in the center of the bone that is responsible for the production of blood cells. The term leukemia means white blood. The term leukocytes refer to white blood cells, which are body’s defense against infections and other foreign substances. When Leukemia occurs there is an uncontrolled increase in the number of white blood cells. When this occurs, these cancerous cells inhibit the production of healthy red blood cells, platelets, and mature white blood cells. Over time the cancerous cells can spread to the bloodstream and lymph nodes. They can also travel to the Central Nervous System and the rest of the body.
There are two types of lymphoma, Hodgkin disease and Non-Hodgkin lymphoma, and even though they are different they both begin the same way. Like other cancers, lymphoma results when cells divide too quickly or do not die because of a discrepancy in their genes. The cells that are affected in this type of cancer are white blood cells called lymphocytes. Lymphocytes make up around 20 to 40 percent of all white blood cells, and are divided into two categories, B or T. Both types help support the immune system by destroying infectious or foreign substances, but B lymphocytes make antibodies to fight these substances while T lymphocytes directly attack the unwanted substances. These cells work in the lymph system which is a part of the immune system. The main jobs of the lymph system are to protect the body from unwanted substances and to transport waste. The system includes many vital organs such as lymph nodes, spleen, bone marrow, thymus, and the digestive tract. When lymphocytes become cancerous they collect in the lymph nodes therefore blocking the passage of waste and other white blood cells while also using the nodes as a system to travel and spread to other parts of body. These cancerous cells do not die and become a burden for the body because they can no longer fulfill their ...
95% of the genetic mutations resulting in CLL are in B-cells. The other 5% are in T- or NK-cells. These mutations result in abnormal lymphocytes (leukemic cells). As the cancer progresses from the blood to the marrow, the increased number of cancerous cells push healthy white blood cells, red blood cells and platelets out of the bone marrow. This “takeover” of the marrow can result in anemia, reduced ability to fight infection and easy bleeding. The increased rates of secondary infections are the result of decreased infection-fighting capacity of white blood cells.
Diagnosis of CLL is usually straight forward. Most cases are usually suspected by the presence of peripheral blood lymphocytosis of small mature lymphocytes with scant cytoplasm. Smear cells are typically feature of the leukaemic cells due to increased cellular fragility. International Workshop on Chronic Lymphocytic Leukaemia criteria for diagnosis require >5x10^9/L of clonal B lymphocytes. The clonality of the circulating b cells must be confirmed with Immunophenotyping by flow cytometry(1). When a clonal population of B
Acute lymphocytic leukemia (ALL) is a form of cancer that occurs when the lymphoid stem cell is affected thereby causing abnormal white blood cells to build up in the bone marrow. This cancer rapidly produces and replaces healthy cells with immature lymphoblast. The leukemia cells moves into the bloodstream to other organs and tissues where further growth and division occurs. The proliferation of cancer cells to other area produces a variety of symptoms. ALL typically occurs in children under the age of 15, however it can happen at any age. ALL is
Leukemia is a cancer of the white blood cells. It begins in the bone marrow, the soft tissue inside the bones. Within the bone marrow is where white blood cells are created, that help fight off bacteria, viruses, and other microorganisms within the body that cause infections. The disease develops to when the white blood cells are being produced out of control. The cells that are being produced do not work properly as they should, they grow faster than a normal cell would and don’t know when to stop growing. Overtime, if not treated properly, the white blood cells will over crowd blood cells, creating a serious problem such as anemia, bleeding and infection. Leukemia cells can spread to the lymph nodes and other organs in the body causing swelling and pain.
Chronic lymphocytic leukemia (CLL): CLL affects lymphoid cells and usually grows slowly. More common in older people.
Childhood leukemia is a fast-growing cancer, most common in teens and children. It is cancer of the white blood cells. The affected cells for in the patient's bone marrow and very quickly travel through the bloodstream, attacking any healthy cells they encounter on the way. There are many things that may cause this cancer.. Some causes can be low immune system, and unhealthy environmental surroundings such as smoking. There are also some argued-about causes that are a bit on the controversial side, such as living near a nuclear power plant, or how old the patient’s mother was when they were born. The most common cause currently known is heredity.
Acute Myeloid Leukemia is one of the three types of leukemia that can form in the blood and bone marrow. Mostly called AML, it is the most common type of acute leukemia that is found in adults over 65 years but can increase with age. Acute Myeloid Leukemia starts in the bone marrow but can travel inside the blood. It is defined as the cancer of myeloid, which can be related to the bone marrow, line of blood cells which is caused by rapid growth of abnormal white blood cells that pile up in the bone marrow. It disrupts the production of normal blood cells. The three different types of blood cells that AML would be in are red blood cells, white blood cells, and platelets which are a small colorless cell fragment. This type of cancer can get worse quickly if it is not treated or discovered. One interesting fact about AML is that they are classified as different names like acute granulocytic leukemia, acute myelioblastic leukemia, acute myelogenous leukemia, and acute nonmphocytic leukemia.
ALL, the most prevalent form of childhood acute leukemia, is a blood cancer. Acute Lymphocytic Leukemia occurs when bone marrow cells develop errors in its DNA (Mayo Clinic). Consequently, cell proliferation occurs without dividing; therefore, resulting in abnormal blood cell production. The bone marrow produces immature cells that develop into leukemic white blood cells called lymphoblasts (Mayo Clinic). Incapable of functioning properly, abnormal cells
In case you're wondering what leukemia is, let me tell you. Leukemia is cancer of the body's blood-forming tissues, which is also involved with the bone marrow. Leukemia is
First I will be explaining what Leukemia is and who, how, and where you can get it. Leukemia is actually an untreatable disease that is known to be in young children but actually
