'''Acute myeloid leukemia''' (uh-KYOOT MY-eh-loyd loo-KEE-mee-uh) is an aggressive (fast-growing) disease in which too many [[myeloblasts]] (immature white blood cells that are not lymphoblasts) are found in the bone marrow and blood. Also called acute myeloblastic leukemia, acute myelogenous leukemia, acute nonlymphocytic leukemia, AML, and ANLL.
'''Acute myeloid leukemia''' ('''AML''') is a type of [[cancer]] that affects the blood and bone marrow. AML is characterized by the rapid growth of abnormal white blood cells that accumulate in the bone marrow and interfere with the production of normal blood cells. It is the most common type of acute leukemia in adults.

== Signs and Symptoms ==
The symptoms of AML are caused by the replacement of normal bone marrow with leukemic cells, which leads to a drop in red blood cells, platelets, and normal white blood cells. Common symptoms include:
* Fatigue
* Fever
* Increased risk of infections
* Bleeding and bruising easily
* Shortness of breath
* Pale skin


== '''Cause ''' ==
== Causes ==
There are many potential causes of AML such as certain [[boold disorders]],[[inherited syndromes]], environmental exposures, and drug exposures; however, most people who develop AML have no identifiable risk factors
The exact cause of AML is not known, but several risk factors have been identified:
* Genetic mutations
* Exposure to radiation
* Previous chemotherapy treatment
* Smoking

title='''{{PAGENAME}}'''
AML involves mutations in the DNA of a cell in the bone marrow. These mutations cause the cell to grow and divide uncontrollably. The accumulation of these abnormal cells, or blasts, in the bone marrow inhibits the ability to produce normal blood cells.

== Diagnosis ==
The signs and symptoms of AML vary but may include easy bruising; bone pain or tenderness; fatigue; fever; frequent nosebleeds; bleeding from the gums; shortness of breath; and/or weightloss.
Diagnosis of AML typically involves:
For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed.
* Complete blood count (CBC)
[[Image:AMLCase-66.jpg|thumb|upright=1.4|Diffusely swollen gums due to infiltration by leukemic cells in a person with AML]]
* Bone marrow biopsy
[[Splenomegaly|Enlargement of the spleen]] may occur in AML,but it is typically mild and [[asymptomatic]].
* Cytogenetic analysis
* Molecular genetic testing


Some people with AML may experience swelling of the gums because of infiltration of leukemic cells into the gum tissue. Rarely, the first sign of leukemia may be the development of a solid leukemic mass or tumor outside of the [[bone marrow]], called a [[chloroma]]. Occasionally, a person may show no symptoms, and the leukemia may be discovered incidentally during a routine [[blood test]].
== Treatment ==
Treatment for AML can vary based on the characteristics of the leukemia and the overall health of the patient. Common treatments include:
* [[Chemotherapy]]
* [[Bone marrow transplantation]]
* Targeted therapy


==Diagnosis==
== Prognosis ==
[[Image:Myeloblast with Auer rod smear 2010-01-27.JPG|thumb|upright=1.4|Bone marrow: myeloblasts with Auer rods seen in AML]]
The prognosis for AML varies widely depending on several factors, including the subtype of AML, the patient's age, and the genetic abnormalities of the leukemia cells. Some subtypes have a relatively good prognosis, while others are more challenging to treat.
The first clue to a diagnosis of AML is typically an abnormal result on a [[complete blood count]]. While an excess of abnormal white blood cells ([[leukocytosis]]) is a common finding with the leukemia, and leukemic [[blasts]] are sometimes seen, AML can also present with isolated decreases in [[platelet]]s, [[red blood cell]]s, or even with a low white blood cell count ([[leukopenia]]).

Acute myeloid leukemia (AML) is a type of cancer that affects the blood and bone marrow. AML is characterized by the rapid growth of abnormal white blood cells that accumulate in the bone marrow and interfere with the production of normal blood cells. It is the most common type of acute leukemia in adults.

Signs and Symptoms[edit]

The symptoms of AML are caused by the replacement of normal bone marrow with leukemic cells, which leads to a drop in red blood cells, platelets, and normal white blood cells. Common symptoms include:

  • Fatigue
  • Fever
  • Increased risk of infections
  • Bleeding and bruising easily
  • Shortness of breath
  • Pale skin

Causes[edit]

The exact cause of AML is not known, but several risk factors have been identified:

  • Genetic mutations
  • Exposure to radiation
  • Previous chemotherapy treatment
  • Smoking

Pathophysiology[edit]

AML involves mutations in the DNA of a cell in the bone marrow. These mutations cause the cell to grow and divide uncontrollably. The accumulation of these abnormal cells, or blasts, in the bone marrow inhibits the ability to produce normal blood cells.

Diagnosis[edit]

Diagnosis of AML typically involves:

  • Complete blood count (CBC)
  • Bone marrow biopsy
  • Cytogenetic analysis
  • Molecular genetic testing

Treatment[edit]

Treatment for AML can vary based on the characteristics of the leukemia and the overall health of the patient. Common treatments include:

Prognosis[edit]

The prognosis for AML varies widely depending on several factors, including the subtype of AML, the patient's age, and the genetic abnormalities of the leukemia cells. Some subtypes have a relatively good prognosis, while others are more challenging to treat.

Epidemiology[edit]

AML is more common in adults than in children and is slightly more prevalent in men than in women. The incidence increases with age.
