A leukémia 4 fő fajtája

Évekkel a diagnózis előtt megjelenhet a leukémia 2009.02.18

Szeretnék kicsit többet tudni a CLL Krónikus Leukémiáról

Az akut leukémiák egyik fő oka a nagy dózisú sugárzás és a benzol vegyület, mely pl. a cigarettában található.

Az akut myeloid leukémia (AML) egy gyors progressziójú, rosszindulatú betegség, melynek során nagy mennyiségű éretlen fehérvérsejt alakul ki a vérben és a csontvelőben. Az akut myeloid leukémia felnőtteket és gyermekeket egyaránt érinthet.

AML is a blood cancer that affects white blood cells, red blood cells, and/or platelets. A person with AML develops abnormal numbers of these cells very quickly, giving the disease the name "acute". The white blood cell (WBC) count may be higher or lower than normal, but the WBCs that are being produced do not function well. Because WBCs are an important part of fighting infections, patients often have multiple infections that don't respond to treatment before they are diagnosed. Some people will have low red blood cell or platelet counts, but this is not always the case.

A CML a vér- és a csontvelõ betegsége, amely az õssejt daganatos átalakulásának következtében jön létre. Az õssejtek olyanok, mint a csontvelõi vetõmagvak, 3 fõ vérsejtféleséggé érnek ki: ezek a fehérvérsejtek, a vörösvértestek és a vérlemezkék.

CML is a chronic blood cancer that starts with a defect in two chromosomes and results in an overgrowth of white blood cells; it is one of the only cancers with a known specific gene mutation. Each person has 23 chromosomes, which contain DNA and a person's genetic makeup (genes). While CML has been recognized since the late 1800's, it was the discovery of the Philadelphia chromosome in 1960 that changed the face of CML.

ALL is a blood cancer that affects the white blood cells. There are two main types of white blood cells, lymphocytes (affected by ALL) and myelocytes (affected by AML). Lymphocytes are further broken down into B and T cell lymphocytes. ALL is a spectrum of disease comprised of several different subtypes, named for the cell type that is affected (B or T) and how abnormal the cell appears under a microscope. A person with ALL develops abnormal numbers of white blood cells rather quickly, usually over weeks, giving the disease the name "acute".
