Acute Myeloid Leukemia (AML)
Acute Myeloid Leukemia (AML) is a type of blood cancer that affects the myeloid cells, which are responsible for producing red blood cells, platelets, and certain white blood cells. The disease is characterized by the rapid growth of abnormal, immature cells called myeloblasts in the bone marrow, which interferes with the normal production and function of blood cells.
Acute Myeloid Leukemia (AML)
AML usually progresses rapidly and requires immediate treatment. Common symptoms of AML include fatigue, pale skin, shortness of breath, frequent infections, easy bruising or bleeding, and bone pain. The exact cause of AML is unknown, but certain risk factors such as exposure to high levels of radiation or certain chemicals, smoking, and certain genetic mutations can increase the likelihood of developing the disease.
Treatment options for AML depend on several factors, including the patient's age, overall health, and specific characteristics of the leukemia cells. Treatment may include chemotherapy, radiation therapy, targeted therapy, stem cell transplant, or a combination of these approaches. The goal of treatment is to eliminate leukemia cells and allow healthy blood cells to be produced again.
AML can be a challenging disease to manage, and the prognosis varies based on several factors. Early diagnosis and prompt treatment can improve the chances of a successful outcome. However, the overall prognosis for AML remains relatively poor compared to other types of leukemia.

Living with AML can have a significant impact on the patient's quality of life, as treatment may cause various side effects such as fatigue, nausea, hair loss, and increased susceptibility to infections. It is important for individuals with AML to work closely with a healthcare team to manage their symptoms, monitor their progress, and receive emotional support throughout their journey.

Causes of Acute Myeloid Leukemia (AML)
- Genetic mutations: Certain genetic mutations in the DNA of bone marrow cells can lead to the development of AML. These mutations can alter the growth and behavior of the cells, causing them to multiply rapidly and abnormally.
- Exposure to certain chemicals and toxins: Exposure to certain chemicals, such as benzene, or high levels of radiation, can increase the risk of developing AML. These substances can damage the DNA in the bone marrow cells, leading to the development of cancer.
- Previous chemotherapy or radiation therapy: Individuals who have received certain types of chemotherapy or radiation therapy for other cancers may have an increased risk of developing AML later in life. These treatments can damage the DNA of healthy cells in the bone marrow, increasing the risk of developing leukemia.
- Smoking: Smoking cigarettes or other tobacco products has been linked to an increased risk of developing AML. The chemicals present in tobacco smoke can enter the bloodstream and affect the bone marrow cells, increasing the likelihood of leukemia development.
- Certain inherited genetic disorders: Some inherited genetic disorders, such as Down syndrome or Fanconi anemia, can increase the risk of developing AML. These disorders affect the functioning of the bone marrow cells, making them more susceptible to developing leukemia.
Medical History and Physical Examination:
A doctor will first gather relevant information about the patient's medical history, including symptoms, risk factors, and previous medical conditions. A thorough physical examination will also be conducted to assess the signs of AML, such as pale skin, easy bruising, swollen lymph nodes, and enlarged liver or spleen.
A complete blood count (CBC) is performed to evaluate the number, size, and shape of blood cells. AML diagnosis typically reveals abnormal levels of white blood cells, red blood cells, and platelets. Additionally, a blood smear may be examined under a microscope to identify abnormal cells.
Bone Marrow Aspiration and Biopsy:
A bone marrow aspiration and biopsy involves the collection of a small sample of bone marrow from the hipbone or another large bone. This procedure helps determine the presence of leukemia cells and assess their characteristics, including their type and genetic abnormalities.
A cytogenetic analysis examines the chromosomes within leukemia cells to identify specific genetic abnormalities. This analysis helps determine prognosis and potential treatment options.
Molecular tests, such as polymerase chain reaction (PCR) or fluorescent in situ hybridization (FISH), may be performed to detect specific gene mutations or rearrangements within leukemia cells. These tests provide further information about the subtype of AML and guide personalized treatment decisions.
Flow cytometry is a technique that analyzes the surface proteins of leukemia cells. It helps determine the immunophenotype of the cells and classify the specific type of AML.
Lumbar Puncture (Optional):
In some cases, a lumbar puncture (spinal tap) may be performed to check if leukemia cells have spread to the cerebrospinal fluid and the central nervous system.
Please note that the above information and methods are generalized, and the actual diagnostic process for Acute Myeloid Leukemia may vary depending on individual cases. It is always advised to consult a medical professional for accurate diagnosis and treatment.
