Pronunciation: [mˈa͡ɪɪlˌɔ͡ɪd luːkˈiːmi͡əz] (IPA) 
Correct spelling for the English word "Myeloid Leukemias" is [mˈa͡ɪɪlˌɔ͡ɪd luːkˈiːmi͡əz], [mˈaɪɪlˌɔɪd luːkˈiːmiəz], [m_ˈaɪ_ɪ_l_ˌɔɪ_d l_uː_k_ˈiː_m_iə_z] (IPA phonetic alphabet).
Myeloid leukemias are a group of malignant neoplasms that arise from abnormal growth and development of myeloid cells in the bone marrow. These myeloid cells are responsible for the production of various blood cells, including red blood cells (erythrocytes), white blood cells (leukocytes), and platelets.
Myeloid leukemias are characterized by the uncontrolled proliferation and accumulation of immature myeloid cells in the bone marrow, leading to impaired production of normal blood cells. As a result, affected individuals may experience symptoms such as anemia, frequent infections, and bleeding tendencies.
There are different subtypes of myeloid leukemias, including acute myeloid leukemia (AML) and chronic myeloid leukemia (CML). Acute myeloid leukemia is typically characterized by the rapid growth of abnormal myeloid cells, leading to quick onset of symptoms. Chronic myeloid leukemia, on the other hand, involves the overproduction of abnormal myeloid cells, which accumulate gradually over time.
The exact causes of myeloid leukemias are not fully understood, but certain risk factors have been identified, including exposure to certain chemicals, radiation, smoking, and certain genetic mutations.
Treatment options for myeloid leukemias depend on several factors, such as the subtype, age of the patient, and overall health. Treatment may involve chemotherapy, radiation therapy, stem cell transplantation, or targeted therapy, which specifically targets the genetic mutations associated with the disease. Prognosis for myeloid leukemias varies widely, with some subtypes being more responsive to treatment than others.
The term "myeloid leukemias" is derived from two main sources:
1. Myeloid: The word "myeloid" comes from the Greek word "myelos", which means marrow. In medical terminology, "myeloid" refers to cells or tissues derived from the bone marrow.
2. Leukemia: The word "leukemia" originates from the Greek words "leukos", meaning white, and "haima", meaning blood. Leukemia is a type of cancer that affects the white blood cells, causing an abnormal proliferation of immature or abnormal white blood cells in the bone marrow and bloodstream.
Combining these two terms, "myeloid leukemias" refer to a group of leukemias involving abnormal growth and proliferation of myeloid cells in the bone marrow and blood.
