Acute Leukemia
What is Acute Leukemia?
Acute leukemia is a type of blood cancer that starts in the bone marrow. This is the soft tissue inside your bones where new blood cells are made. In acute leukemia, the bone marrow produces too many immature white blood cells called blast cells. These abnormal cells crowd out healthy blood cells and spread quickly through the bloodstream.
There are two main types of acute leukemia. Acute lymphoblastic leukemia, or ALL, affects lymphoid cells. Acute myeloid leukemia, or AML, affects myeloid cells. Both types progress rapidly and require immediate medical attention. The word acute means the disease develops quickly, usually over weeks or months.
Healthy bone marrow makes red blood cells to carry oxygen, white blood cells to fight infection, and platelets to help blood clot. When blast cells take over, your body cannot produce enough normal blood cells. This leads to symptoms like fatigue, infections, and easy bruising. Early detection through blood testing can help identify abnormal blast cell levels before serious complications develop.
Symptoms
- Fatigue and weakness that does not improve with rest
- Frequent infections or fever
- Easy bruising or bleeding, including nosebleeds and bleeding gums
- Tiny red spots on the skin called petechiae
- Bone or joint pain
- Swollen lymph nodes in the neck, armpits, or groin
- Pale skin
- Shortness of breath during normal activities
- Unexplained weight loss
- Night sweats
Some people experience vague symptoms in the early stages that mimic less serious conditions. Others may feel suddenly very ill as blast cells multiply rapidly. Because acute leukemia progresses quickly, symptoms often appear and worsen over just a few weeks.

Causes and risk factors
Acute leukemia develops when DNA changes occur in bone marrow cells. These genetic mutations cause cells to grow and divide uncontrollably. Most cases happen without a clear cause, but certain risk factors increase your chances. Previous chemotherapy or radiation therapy for other cancers can damage bone marrow cells. Exposure to high levels of radiation or certain chemicals like benzene also raises risk. Some genetic disorders, including Down syndrome, increase leukemia likelihood.
Smoking is a known risk factor for acute myeloid leukemia. A family history of leukemia may slightly increase risk, though most people with acute leukemia have no family history. Age plays a role, with AML more common in adults over 65 and ALL more common in children under 5. Unlike some cancers, lifestyle factors like diet and exercise do not appear to directly cause acute leukemia. Most people diagnosed have no controllable risk factors.
How it's diagnosed
Doctors diagnose acute leukemia through blood tests and bone marrow examination. A complete blood count, or CBC, often shows abnormal results including high or low white blood cell counts. The key finding is the presence of blast cells in the blood. Rite Aid testing can detect abnormal blast cell levels, which may prompt further evaluation by a specialist. Normal blood should contain very few or no blast cells.
If blast cells are found, doctors perform a bone marrow biopsy to confirm the diagnosis. This involves taking a small sample from the hip bone to examine under a microscope. Additional tests identify the specific type of leukemia and genetic markers. Flow cytometry analyzes cell surface proteins. Cytogenetic testing looks for chromosome abnormalities. These tests help determine the best treatment approach and predict how the disease will respond.
Treatment options
- Chemotherapy is the primary treatment, using powerful drugs to kill cancer cells
- Targeted therapy drugs attack specific proteins on leukemia cells
- Stem cell transplant may be needed to replace diseased bone marrow
- Radiation therapy is sometimes used to treat leukemia in the brain or spinal cord
- Clinical trials offer access to new treatments being studied
- Supportive care includes blood transfusions and antibiotics to manage symptoms
- Nutritious eating helps maintain strength during treatment
- Rest and gentle activity as tolerated support recovery
- Avoiding infections through good hygiene and staying away from sick people
- Regular monitoring with blood tests tracks treatment response

Frequently asked questions
Acute leukemia develops quickly over weeks to months and involves immature blast cells. Chronic leukemia develops slowly over years and involves more mature cells. Acute forms require immediate treatment, while chronic forms may be monitored before treatment starts. The two types also respond to different treatment approaches.
Yes, blood tests can detect abnormal blast cells before symptoms become severe. A routine blood count may reveal unusual results that prompt further testing. Rite Aid testing measures blast cell levels and other blood markers. Early detection allows for quicker diagnosis and treatment.
Many people with acute leukemia achieve remission, meaning no cancer cells are detected. Cure rates vary by type, age, and other factors. Acute lymphoblastic leukemia has high cure rates in children, often above 85%. Acute myeloid leukemia cure rates are lower but improving with newer treatments.
Blast cells are immature blood cells that normally develop into healthy white blood cells. In acute leukemia, these cells never mature and multiply uncontrollably. They crowd out normal blood cells and cannot fight infections properly. Elevated blast cells in blood or bone marrow are a key sign of acute leukemia.
Treatment typically lasts 6 months to 2 years depending on the type and response. Initial intensive chemotherapy usually requires a hospital stay of several weeks. Maintenance therapy continues on an outpatient basis. Some patients need stem cell transplants, which extend the treatment timeline.
Untreated acute leukemia is life threatening and progresses rapidly. Blast cells continue multiplying and crowding out healthy blood cells. This leads to severe infections, uncontrolled bleeding, and organ failure. Without treatment, acute leukemia can be fatal within weeks to months.
Most cases of acute leukemia cannot be prevented through lifestyle changes. Unlike some cancers, diet and exercise do not significantly affect risk. Avoiding smoking reduces risk of acute myeloid leukemia. Limiting exposure to radiation and toxic chemicals like benzene may help, though most people have no controllable risk factors.
Acute lymphoblastic leukemia is most common in children under 5 and adults over 50. Acute myeloid leukemia is more common in adults over 65. People with certain genetic disorders, previous cancer treatment, or chemical exposure have higher risk. Most people diagnosed have no known risk factors.
See a doctor immediately if your blood test shows blast cells. Your doctor will likely refer you to a hematologist, a blood specialist. You will need a bone marrow biopsy and additional tests to confirm or rule out leukemia. Quick action is important because acute leukemia requires prompt treatment.
Relapse is possible even after successful treatment and remission. The risk varies based on the type of leukemia and individual factors. Regular blood tests help detect relapse early when it is easier to treat. Some people need additional chemotherapy or stem cell transplants if leukemia returns.
