Acute Myeloid Leukemia: Symptoms, Causes, Treatment
ابيضاض الدم النخاعي الحاد
Acute myeloid leukemia is a rapidly developing blood and marrow cancer that disrupts normal blood-cell production. Urgent assessment and subtype identification guide treatment.
What is Acute Myeloid Leukemia?
Immature cells accumulate and affect red cells, infection-fighting cells and platelets. Genetic subtypes differ, so one regimen cannot represent every case or age group.

Symptoms
Pallor, fatigue, fever, infection, bruising or gum and nose bleeding may develop over weeks. These symptoms are not specific to cancer but need medical explanation.
Causes
Genetic changes develop in blood-forming cells. Disease may arise without a known cause or after another marrow disorder, previous cancer treatment or certain exposures.
Risk factors
Age, smoking, some previous cancer treatments, marrow disorders and certain inherited syndromes increase risk. Many people have no clear risk factor; a risk factor alone does not establish disease.
Diagnosis
Blood counts and a blood film lead to marrow examination, cell-marker studies and genetic testing. Results establish subtype and guide care; one symptom or count cannot diagnose AML alone.
Treatment
Treatment may involve intensive chemotherapy or less intensive combinations, mutation-directed medicines, supportive care and sometimes stem cell transplantation. Certain subtypes, including acute promyelocytic leukemia, need a distinct urgent approach.
Complications
Disease and treatment may cause serious infection, bleeding, anemia and metabolic disturbances. Follow-up monitors response, residual disease, later adverse effects and emotional support needs.
Prevention
Not every case can be prevented. Avoid tobacco and unsafe occupational exposure to harmful chemicals. Do not avoid necessary treatment or medical imaging because of a generalized leukemia fear.
When to see a doctor
Unexplained bleeding or bruising with fatigue and fever needs prompt assessment. Major bleeding, breathlessness or altered consciousness is an emergency; fever during cancer treatment needs immediate team contact.
