Leukemia | Borka Association for Cancer
Leukemia is cancer that starts in the organs aro 2011 that produce blood, mainly bone marrow and lymphatic system. Depending on the specific characteristics, leukemia can be divided into two major types: acute and chronic. Acute leukemia brzonapreduvachki leukemias, and chronic leukemias progress slowly. Most children's leukemia from acute form.
Although cells mature and emerge as normal, they do not function like normal cells. Depending on the type of white blood cell involved, chronic leukemia can be classified as chronic lymphocytic leukemia or chronic myelogenous leukemia. Chronic leukemia develops very gradually. Abnormal lymphocytes multiply slowly, but poorly regulated manner. They live much longer and thus their number increases in the body. Both types of chronic leukemia can be easily recognized under the microscope. Chronic lymphocytic leukemia (CLL) involves the T or B lymphocytes. B cell abnormalities are more common than T cell abnormalities. T cells are affected only in 5% of patients. T and B lymphocytes differ from other types of white blood cells based on their size and lack of granules in them. In chronic myelogenous leukemia (CML), the cells that are affected are the granulocytes. Chronic lymphocytic leukemia (CLL) often shows no early symptoms and can remain undetected for a long time. Chronic myelogenous leukemia (CML), aro 2011 on the other hand, can thrive in a more acute form. Acute leukemias
In acute leukemia, the maturation of white blood cells is interrupted. Immature cells (or "blasts") multiply rapidly and begin to accumulate in various organs and tissues, thereby affecting their normal functioning. This uncontrolled proliferation of immature cells in the bone marrow affects the production of normal red blood cells and platelets. Acute leukemias are two types: acute lymphocytic leukemia and acute myelogenous leukemia. Different types of white blood cells involved in both leukemia. In acute lymphocytic leukemia (ALL), T and B lymphocytes become cancerous. B cell leukemias are more common than T cell leukemia. Acute myelogenous leukemia, also called acute nelimfocitna leukemia (ANLL), a cancer of monocytes and / or granulocytes. Leukemia affecting 2% of all cancers. aro 2011 Since leukemia is the most common form of childhood cancer, it is often considered a disease of childhood. However, leukemia affecting aro 2011 adults nine times around children. Half of the cases occur in people 60 years or older. The incidence of acute and chronic leukemia is almost the same. Estimates of GLOBOCAN, morbidity for leukemia is about 200 000 new cases in 2008 worldwide aro 2011 and 87 cases in Macedonia, with 61 deaths. Internationally, leukemia is the fourth most common cancer in people aro 2011 aged 15 to 19 years.
Causes and symptoms Leukaemia affects both sexes and all ages, and its cause is largely unknown. aro 2011 However, chronic leukemia is associated with genetic abnormalities and environmental factors. For example, exposure aro 2011 to ionizing aro 2011 radiation and certain organic chemicals such as benzene, are believed to increase the risk of getting leukemia. Chronic leukemia occurs in some people who are infected with two human retroviruses (HTLV-I and HTLV-II). aro 2011 Abnormal chromosome known as the Philadelphia chromosome seen in 90% of cases of CML. The incidence of leukemia (acute and chronic) is slightly higher in men than in women. Higher incidence of leukemia has also been reported in individuals with Down syndrome and other genetic abnormalities. History of disease by damaging bone marrow, such as aplastic aro 2011 anemia or history of cancer of the lymphatic system puts people at high risk of developing acute leukemia. Similarly, the use of anticancer aro 2011 drugs, immunosuppressants and antibiotic chloramphenicol also considered risk factors for developing acute leukemia.

Like all cancers, leukaemias are best treated when detected early. No screening tests available. If a doctor aro 2011 has reason to suspect leukemia, he will conduct a thorough physical examination to detect enlarged lymph nodes in the neck, armpits and pelvic area. Swollen gums, enlarged aro 2011 liver or spleen, bruises or pinhole red rash all over the body are some of the signs of leukemia. You can make urine and blood tests to check the possible presence of microscopic amounts of blood in the urine and to obtain a complete differential blood count. Abnormal blood test might suggest leukemia, however, the diagnosis should be confirmed by more specific tests.
