Acute Myelogenous Leukemia Symptoms: Acute Myelogenous Leukemia (AML) is a fast-progressing cancer of the blood and bone marrow. It stands as one of the most common types of leukemia in adults, though it can affect individuals of all ages.
AML is characterized by the rapid growth of abnormal cells that impede the bone marrow’s ability to produce healthy blood cells.
In this comprehensive guide, we will delve deep into the symptoms, causes, and intricate details of AML.
What is Acute Myelogenous Leukemia?
Acute Myelogenous Leukemia, commonly referred to as AML, is a type of cancer that originates in the bone marrow and quickly progresses, leading to an increase in the number of immature white blood cells in the bloodstream and bone marrow.
Brief Description of the Bone Marrow and Blood Cell Formation
The bone marrow is a spongy, fatty tissue found inside larger bones, and it’s responsible for producing all types of blood cells: red blood cells, white blood cells, and platelets. Blood cell formation, or hematopoiesis, starts with a stem cell. This stem cell divides and matures into various types of blood cells, each with its specific function in the body. Healthy bone marrow maintains a balance of these cells. However, in conditions like AML, this balance is disrupted, leading to an overproduction of abnormal cells.
When considering AML or any other medical condition, it’s essential to consult with healthcare professionals to gain a comprehensive understanding and accurate diagnosis.
Acute Myelogenous Leukemia Symptoms
Recognizing these signs early can be essential for timely diagnosis and treatment. Let’s explore the common and less frequent symptoms associated with AML:
Common Symptoms
Fatigue and Weakness: One of the initial indicators of AML is a feeling of constant tiredness, even after adequate rest. This fatigue is more than just everyday exhaustion and can impede daily activities.
Fever and Night Sweats: People with AML often experience fevers that are not related to an infection, accompanied by night sweats which can drench sleepwear and sheets.
Shortness of Breath: Simple tasks might leave an individual gasping for breath due to a decreased number of red blood cells.
Pale or Sallow Skin: A lack of healthy red blood cells can lead to a pallid complexion, making the skin look unusually pale or yellowish.
Symptoms Due to Low Blood Cell Counts
Anemia (low red blood cells): Symptoms like fatigue, paleness, and dizziness can manifest when the body doesn’t have enough red blood cells.
Thrombocytopenia (low platelets): A decline in the number of platelets can result in easy bruising and bleeding. Even minor injuries might bleed excessively.
Neutropenia (low neutrophils): Neutrophils play a vital role in warding off infections. A decreased count can lead to an increased risk of contracting infections.
Symptoms Related to Bone Marrow Expansion
Bone Pain: As leukemia cells crowd the bone marrow, it can cause pain, especially in the sternum (breastbone) or ribs.
Swelling or Discomfort in the Abdomen: An accumulation of leukemia cells in the liver or spleen can cause these organs to enlarge, leading to abdominal discomfort.
Less Common Symptoms
Gum Swelling or Tenderness: Some people might notice their gums becoming swollen or tender, making it uncomfortable to chew.
Skin Rashes or Nodules: Unusual rashes or small lumps under the skin may also appear in some AML patients.
Unintended Weight Loss: Despite maintaining regular eating habits, some individuals may notice an unexplained drop in their weight.
Enlarged Spleen or Liver: In certain cases, the spleen or liver may enlarge, leading to a fullness or swelling in the abdomen.
Awareness of these symptoms is crucial. If you or a loved one experience any of these signs, it’s essential to consult with a healthcare professional for proper evaluation and guidance.
Causes of Acute Myelogenous Leukemia
The exact cause of AML isn’t fully understood, but there are several factors that have been linked to an increased risk of developing the disease.
Genetic Factors: Certain genetic mutations can increase the likelihood of developing AML. Some of these mutations can be inherited, but most occur spontaneously.
Previous Cancer Treatments: People who have undergone chemotherapy or radiation therapy for other types of cancers may have a heightened risk of developing AML later in life.
Exposure to Certain Chemicals: Long-term exposure to certain chemicals, particularly benzene, which is used in the petroleum and chemical industries, has been linked to an increased risk of AML.
Smoking: Cigarette smoke contains benzene and other harmful chemicals that can increase the risk of AML.
Radiation Exposure: People exposed to high levels of radiation, like survivors of nuclear reactor accidents, are at a greater risk of developing AML.
Blood Disorders: Certain blood disorders, such as chronic myeloid leukemia or myelodysplastic syndromes, can evolve into AML.
Age: The risk of developing AML increases with age, with most cases occurring in adults over 60.
It’s essential to note that having one or more of these risk factors doesn’t mean that someone will definitely develop AML. Many people with the disease have no known risk factors. Continuous research is being conducted to better understand the causes and develop effective treatments for AML.
Risk Factors
AML doesn’t have a single, identifiable cause. Instead, various risk factors increase the likelihood of developing this leukemia type:
Prior Chemotherapy or Radiation Therapy: People who’ve undergone specific chemotherapy treatments or radiation therapy for other cancers are at an elevated risk of developing AML later in life.
Exposure to Certain Chemicals: Certain chemicals are known to raise the risk of AML. Benzene, which is used in the rubber industry, oil refineries, and some chemical plants, is one such chemical. Regular and prolonged exposure can increase the chances of AML.
Certain Blood Disorders and Genetic Syndromes: Some blood disorders, like myelodysplastic syndrome, predispose individuals to AML. Additionally, certain genetic syndromes like Down syndrome can also increase the risk.
Diagnosis and Treatment
Diagnosing AML often involves a series of blood tests, bone marrow tests, and imaging tests. Once diagnosed, treatment options might encompass:
1. Chemotherapy: This is the primary modality for AML. It involves drugs that kill cancer cells or prevent them from growing.
2. Stem Cell Transplant: Healthy cells from a donor replace the patient’s diseased bone marrow.
3. Targeted Therapy: Drugs specifically target cancer cells, causing minimal harm to normal cells.
4. Radiation Therapy: High-energy radiation kills cancer cells and shrinks tumors.
5. Clinical Trials: These are research studies that test new treatments or newly approved treatments.
FAQs about Acute Myelogenous Leukemia (AML)
Navigating the complexities of Acute Myelogenous Leukemia (AML) can be challenging. Here’s a compilation of some frequently asked questions to help shed light on its symptoms and causes.
1. What is Acute Myelogenous Leukemia (AML)?
AML is a type of cancer that starts in the bone marrow (the soft inner part of certain bones, where new blood cells are made) but often moves into the blood. It can sometimes spread to other parts of the body including the lymph nodes, liver, spleen, and central nervous system.
2. What are the most common symptoms of AML?
The symptoms of AML can vary from one person to another but commonly include:
- Fatigue or weakness
- Frequent infections
- Easy bruising or bleeding
- Pain or tenderness in the bones or joints
- Shortness of breath
- Pale or sallow skin
- Fever or night sweats

The exact cause of AML isn’t known. However, several factors may increase the risk of developing this condition:
- Exposure to certain chemicals, such as benzene
- Previous chemotherapy or radiation treatments
- Certain genetic disorders like Down syndrome
- Chronic exposure to smoking
- A history of blood disorders
It’s worth noting that many people with AML have none of these risk factors, and many people who have these risk factors don’t develop leukemia.
4. Can exposure to radiation lead to AML?
Yes, exposure to high levels of radiation is a known risk factor for AML. This could be from previous radiation therapy or from significant environmental exposure, such as a nuclear accident.
5. How is AML different from other types of leukemia?
AML primarily affects the myeloid cells, which are responsible for producing red blood cells, platelets, and some types of white blood cells. Other types of leukemia, like Chronic Lymphocytic Leukemia (CLL), affect different types of cells in the blood. The onset of AML is typically rapid and acute, hence its name, while other leukemias may progress more slowly.
