Acute Myeloid Leukemia

What is leukemia?

From: MedlinePlus, National Library of Medicine

Leukemia is a term for cancers of the blood cells. Leukemia starts in blood-forming tissues such as the bone marrow. Your bone marrow makes the cells which will develop into white blood cells, red blood cells, and platelets. Each type of cell has a different job:

• White blood cells help your body fight infection
• Red blood cells deliver oxygen from your lungs to your tissues and organs
• Platelets help form clots to stop bleeding

When you have leukemia, your bone marrow makes large numbers of abnormal cells. This problem most often happens with white blood cells. These abnormal cells build up in your bone marrow and blood. They crowd out the healthy blood cells and make it hard for your cells and blood to do their work.

What is acute myeloid leukemia (AML)?

Acute myeloid leukemia (AML) is a type of acute leukemia. "Acute" means that the leukemia usually gets worse quickly if it's not treated. In AML, the bone marrow makes abnormal myeloblasts (a type of white blood cell), red blood cells, or platelets. When the abnormal cells crowd out the healthy cells, it can lead to infection, anemia, and easy bleeding. The abnormal cells can also spread outside the blood to other parts of the body.

There are several different subtypes of AML. The subtypes are based on how developed the cancer cells are when you get your diagnosis and how different they are from normal cells.

What causes acute myeloid leukemia (AML)?

From: MedlinePlus, National Library of Medicine

AML happens when there are changes in the genetic material (DNA) in bone marrow cells. The cause of these genetic changes is unknown. However, there are certain factors that raise your risk of AML.

Who is at risk for acute myeloid leukemia (AML)?

From: MedlinePlus, National Library of Medicine

The factors that raise your risk of AML include:

• Being male
• Smoking, especially after age 60
• Having had chemotherapy or radiation therapy
• Treatment for acute lymphoblastic leukemia (ALL) as a child
• Exposure to the chemical benzene
• A history of another blood disorder such as myelodysplastic syndrome

What are the symptoms of acute myeloid leukemia (AML)?

From: MedlinePlus, National Library of Medicine

The signs and symptoms of AML include:

• Fever
• Shortness of breath
• Easy bruising or bleeding
• Petechiae, which are tiny red dots under the skin. They are caused by bleeding.
• Weakness or feeling tired
• Weight loss or loss of appetite
• Bone or joint pain, if the abnormal cells build up near or inside the bones

How is acute myeloid leukemia (AML) diagnosed?

From: MedlinePlus, National Library of Medicine

Your health care provider may use many tools to diagnose AML and figure out which subtype you have:

• A physical exam
• A medical history
• Blood tests, such as a complete blood count (CBC) and blood smear
• Bone marrow tests. There are two main types - bone marrow aspiration and bone marrow biopsy. Both tests involve removing a sample of bone marrow and bone. The samples are sent to a lab for testing.
• Genetic tests to look for gene and chromosome changes

If you are diagnosed with AML, you may have additional tests to see whether the cancer has spread. These include imaging tests and a lumbar puncture, which is a procedure to collect and test cerebrospinal fluid (CSF).

What are the treatments for acute myeloid leukemia (AML)?

From: MedlinePlus, National Library of Medicine

Treatments for AML include:

Which treatment you get often depends on which subtype of AML you have. Treatment is usually done in two phases:

• Chemotherapy
• Radiation therapy
• Chemotherapy with stem cell transplant
• Other anticancer medicines
• The goal of the first phase is to kill the leukemia cells in the blood and bone marrow. This puts the leukemia into remission. Remission means that the signs and symptoms of cancer are reduced or have disappeared.
• The second phase is known as post-remission therapy. Its goal is to prevent a relapse (return) of the cancer. It involves killing any remaining leukemia cells that may not be active but could begin to regrow.

Which doctor should you see?

The suggested department for discussing Acute Myeloid Leukemia is Haematology, with a haematologist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• Which blood-cell, marrow, bleeding or clotting finding matters most?
• Does the diagnosis need confirmation or a more precise subtype?
• Which symptoms or laboratory changes should trigger earlier review?

Treatment discussions and follow-up

Where the source describes treatments, these are an overview of possible care, not a prescription for an individual. Ask which option applies to the confirmed diagnosis, what benefit is expected, what adverse effects to watch for and how progress will be assessed. Availability, approvals and local practice can differ from the country described in the source.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
