Causes & Risk Factors
Several factors can contribute to Leukemia (Acute Myeloid Leukemia).
The exact cause of acute myeloid leukemia remains unclear, but scientists understand the basic mechanism.
The exact cause of acute myeloid leukemia remains unclear, but scientists understand the basic mechanism. AML begins when DNA damage occurs in stem cells within your bone marrow - the spongy tissue inside your bones where blood cells are made. This genetic damage causes these stem cells to grow and divide uncontrollably, creating abnormal white blood cells called blasts that can't function properly.
Think of your bone marrow as a highly organized factory producing different types of blood cells on a precise schedule.
Think of your bone marrow as a highly organized factory producing different types of blood cells on a precise schedule. In AML, the production line goes haywire, churning out defective white blood cells while reducing the output of healthy red blood cells, normal white blood cells, and platelets. These cancerous blasts accumulate rapidly, crowding out healthy cells and eventually spilling into the bloodstream.
While we can't pinpoint what triggers the initial DNA damage in most cases, researchers have identified several factors that increase the likelihood of these genetic changes occurring.
While we can't pinpoint what triggers the initial DNA damage in most cases, researchers have identified several factors that increase the likelihood of these genetic changes occurring. Most people with risk factors never develop AML, and many people diagnosed with AML have no known risk factors at all. The disease appears to result from a complex interaction between genetic vulnerability and environmental influences that scientists are still working to understand.
Risk Factors
- Age over 60 years
- Previous chemotherapy or radiation therapy for other cancers
- Exposure to high levels of radiation
- Long-term exposure to benzene or formaldehyde
- History of blood disorders like myelodysplastic syndrome
- Genetic disorders such as Down syndrome
- Family history of AML or related blood cancers
- Smoking cigarettes
- Previous treatment with alkylating agents
Diagnosis
How healthcare professionals diagnose Leukemia (Acute Myeloid Leukemia):
- 1
Diagnosing acute myeloid leukemia typically begins when you visit your doctor with concerning symptoms like persistent fatigue, frequent infections, or unusual bleeding.
Diagnosing acute myeloid leukemia typically begins when you visit your doctor with concerning symptoms like persistent fatigue, frequent infections, or unusual bleeding. Your doctor will start with a physical examination, checking for enlarged lymph nodes, liver, or spleen, and looking for signs like pale skin or small red spots that might indicate low blood cell counts.

The first crucial test is a complete blood count (CBC), which measures the levels of different blood cells.
The first crucial test is a complete blood count (CBC), which measures the levels of different blood cells. In AML, this test often reveals abnormal numbers - too few red blood cells and platelets, and either too many or too few white blood cells. More importantly, the blood sample may show blast cells, which normally shouldn't appear in peripheral blood. If your CBC results suggest leukemia, your doctor will order additional blood tests and likely refer you to a hematologist-oncologist.

The definitive diagnosis requires a bone marrow biopsy, where doctors extract a small sample of bone marrow, usually from your hip bone.
The definitive diagnosis requires a bone marrow biopsy, where doctors extract a small sample of bone marrow, usually from your hip bone. This procedure, done under local anesthesia, allows specialists to examine the bone marrow cells under a microscope and perform genetic testing. They'll look for the percentage of blast cells (20% or more indicates AML) and identify specific genetic mutations that help determine the exact subtype of AML and guide treatment decisions. Additional tests might include:

Complications
- Acute myeloid leukemia can lead to serious complications, both from the disease itself and from treatment.
- The most immediate dangers come from low blood cell counts: severe infections due to lack of healthy white blood cells, life-threatening bleeding from low platelet counts, and profound anemia causing heart strain and breathing difficulties.
- These complications can develop rapidly and often require immediate medical attention, including blood transfusions, platelet transfusions, and aggressive antibiotic treatment.
- Treatment-related complications vary depending on the intensity of therapy but may include increased infection risk during chemotherapy, organ damage (particularly to the heart, liver, or kidneys), infertility, and an elevated risk of developing secondary cancers years later.
- Stem cell transplant recipients face additional risks including graft-versus-host disease, where donor cells attack the recipient's tissues.
- However, most treatment-related complications are manageable with proper medical care, and the benefits of treatment typically far outweigh these risks.
- Long-term survivors may need ongoing monitoring for late effects, but many people return to normal, active lives after successful treatment.
Prevention
- Unfortunately, most cases of acute myeloid leukemia can't be prevented because the exact causes remain unknown, and many risk factors like age and genetics can't be changed.
- However, you can reduce your risk by avoiding known environmental triggers when possible.
- If you work in industries that use benzene, formaldehyde, or other chemicals linked to AML, follow all safety protocols, use proper protective equipment, and ensure adequate ventilation in your workspace.
- Quitting smoking represents one of the most important preventive steps you can take.
- Tobacco use increases AML risk and worsens treatment outcomes if you do develop the disease.
- If you're a cancer survivor who received chemotherapy or radiation therapy, maintain regular follow-up appointments with your oncologist, as these treatments can increase AML risk years later.
- While you can't prevent this potential complication, early detection through monitoring can improve outcomes.
- For people with pre-existing blood disorders like myelodysplastic syndrome or myeloproliferative disorders, working closely with a hematologist for ongoing monitoring and management may help detect AML early if it develops.
- Some research suggests that maintaining a healthy lifestyle with regular exercise, a balanced diet rich in fruits and vegetables, and avoiding excessive alcohol might provide some protective benefits, though the evidence isn't definitive for AML specifically.
Treatment for acute myeloid leukemia typically unfolds in two main phases: induction therapy to achieve remission, followed by consolidation therapy to prevent relapse.
Treatment for acute myeloid leukemia typically unfolds in two main phases: induction therapy to achieve remission, followed by consolidation therapy to prevent relapse. The goal of induction therapy is to destroy as many leukemia cells as possible and restore normal blood cell production. Most patients receive a combination of chemotherapy drugs, commonly cytarabine (Ara-C) plus an anthracycline like daunorubicin, administered through an IV over several days in the hospital.
Once remission is achieved - meaning blast cells drop below 5% in the bone marrow and blood counts normalize - consolidation therapy begins.
Once remission is achieved - meaning blast cells drop below 5% in the bone marrow and blood counts normalize - consolidation therapy begins. This phase aims to eliminate any remaining leukemia cells that standard tests can't detect. Treatment options include additional rounds of high-dose chemotherapy, stem cell transplantation, or targeted therapy drugs depending on your specific genetic markers and overall health. Younger, healthier patients often receive more intensive treatment, while older adults or those with other health conditions may receive modified regimens.
Targeted therapies have revolutionized AML treatment in recent years.
Targeted therapies have revolutionized AML treatment in recent years. If your leukemia cells have specific genetic mutations, you might benefit from drugs like:
- FLT3 inhibitors (midostaurin, gilteritinib) for FLT3 mutations - IDH inhibitor
- FLT3 inhibitors (midostaurin, gilteritinib) for FLT3 mutations - IDH inhibitors (ivosidenib, enasidenib) for IDH1 or IDH2 mutations - BCL-2 inhibitors (venetoclax) often combined with other agents - Gemtuzumab ozogamicin for CD33-positive AML
Stem cell transplantation offers the best chance for long-term cure in many cases, particularly for high-risk AML or relapsed disease.
Stem cell transplantation offers the best chance for long-term cure in many cases, particularly for high-risk AML or relapsed disease. This involves receiving high-dose chemotherapy followed by infusion of healthy stem cells, either from your own body (autologous) or a donor (allogeneic). The procedure requires weeks of hospitalization and months of recovery, but it can provide durable remissions when other treatments might not suffice.
Living With Leukemia (Acute Myeloid Leukemia)
Living with acute myeloid leukemia requires adapting to a new reality while maintaining hope and quality of life. During active treatment, you'll spend considerable time in the hospital or clinic, so creating a support system becomes crucial. Many people find it helpful to designate a family member or friend as their primary advocate who can attend appointments, help track medications, and communicate with the medical team when you're not feeling well. Don't hesitate to ask questions about your treatment plan, side effects to expect, and how to manage symptoms at home.
