Acute Myeloid Leukemia (AML) Overview
Acute Myeloid Leukemia (AML) is a type of cancer that affects the blood and bone marrow. It develops when the bone marrow produces abnormal white blood cells, red blood cells, or platelets. These abnormal cells grow rapidly and interfere with the production of normal blood cells, making it hard for the body to fight infections, control bleeding, and transport oxygen. It is the commonest type of acute leukemia in adults.
Symptoms of AML
The symptoms of AML can appear suddenly and worsen quickly. Common symptoms include:
Fatigue and weakness
Frequent infections
Easy bruising or bleeding (such as nosebleeds or bleeding gums)
Fever and night sweat
Pale skin
Shortness of breath
Unexplained weight loss
Swollen gums
Bone or joint pain
Small red spots under the skin (petechiae)
Causes of AML
AML occurs due to changes (mutations) in the DNA of myeloid cells in the bone marrow.These mutations cause abnormal blood cell (a lot of immature white blood cells called myeloblast) production. While the exact cause of these mutations is not always known, several factors can contribute to their development.
Risk Factors for AML
Certain factors can increase the risk of developing AML, including:
Age: AML is more common in older adults, typically those over 60.
Exposure to chemicals: Long-term exposure to harmful chemicals like benzene may raise the risk.
Previous cancer treatments: Chemotherapy or radiation therapy for other cancers can increase the chance of developing AML later.
Smoking: Tobacco contains harmful substances that may contribute to AML.
Genetic disorders: Conditions like Down syndrome and other inherited blood disorders can increase the risk
Blood disorders: Some pre-existing blood conditions, like myelodysplastic syndromes, can lead to AML.
History of AML in close blood relative increases chance of AML.
Diagnosis of AML
Doctors diagnose AML through various tests, including:
Blood tests: A complete blood count (CBC) can detect abnormal levels of white blood cells, red blood cells, and platelets.
Bone marrow biopsy: A small sample of bone marrow is taken from the hip bone by a bone marrow aspiration needle and examined for cancerous cells.
Genetic testing: Identifies specific gene mutations that help determine treatment options.
Imaging tests: X-rays, CT scans, or MRIs may be used to check for infections or complications.
Lumbar puncture (spinal tap)– Checks if cancer has spread to the brain or spinal cord.
If diagnosed as AML then test for genetic changes in blood and bone marrow to determine the specific subtype of AML.
Treatment of AML
Treatment for AML depends on factors such as age, overall health, and genetic mutations. The main treatments include:
Chemotherapy: The most common treatment, using strong drugs to kill leukemia cells. Repeated treatment may be necessary,
Targeted therapy: Medications that focus on specific genetic changes in leukemia cells.
Radiation therapy: Uses high-energy rays to kill cancer cells or to prepare for a bone marrow transplant.
Bone marrow transplant (Stem cell transplant): Replaces diseased bone marrow with healthy stem cells from a donor
Supportive care: Blood transfusions, antibiotics, and pain management to ease symptoms and complications.
Coping with AML and Finding Support
A diagnosis of AML can be overwhelming, but support is available. Here are some ways to cope:
Emotional support: Talk to family, friends, or support groups for encouragement and understanding.
Counseling and therapy: Professional counselors can help manage anxiety, depression, and emotional distress.
Healthy lifestyle: Eating a balanced diet, getting enough rest, and light physical activity can help maintain strength.
Medical support: Regular check-ups and open communication with doctors are essential for managing the condition.
Joining support groups: Connecting with others who have AML can provide comfort and useful insights.
Conclusion
Acute Myeloid Leukemia is a serious condition, but treatments are available to help manage the disease. Early diagnosis and treatment improve the chances of recovery.Â
