Types of Myeloid Leukemia
There are several types of myeloid leukemia, with the most common being acute myeloid leukemia (AML) and chronic myeloid leukemia (CML). AML is a rapidly progressing cancer that starts in the bone marrow and quickly spreads to the blood and other organs. It is characterized by an overproduction of immature myeloid cells, which can crowd out normal blood cells and lead to symptoms such as fatigue, easy bruising, and infections.
CML, on the other hand, is a slow-growing cancer that starts in the bone marrow and slowly progresses over time. It is characterized by the presence of a genetic abnormality called the Philadelphia chromosome, which leads to the overproduction of mature myeloid cells.
Another type of myeloid leukemia is myelodysplastic syndrome (MDS), which is a group of disorders that affect the production of blood cells in the bone marrow. MDS can progress to AML in some cases, making it a pre-leukemic condition. Patients with MDS may experience symptoms such as anemia, easy bruising, and infections due to a lack of healthy blood cells.
Finally, there is myeloproliferative neoplasms (MPNs), which are a group of disorders characterized by the overproduction of one or more types of blood cells in the bone marrow.
MPNs can progress to acute leukemia in some cases and may present with symptoms such as enlarged spleen, night sweats, and weight loss.
In a nutshell, myeloid leukemia encompasses a variety of diseases that affect the bone marrow and blood cells. Understanding the different types of myeloid leukemia, such as AML, CML, MDS, and MPNs, is important for accurate diagnosis and treatment.
