Overview

Leukemia is a cancer of the blood-forming tissues, including the bone marrow. It interferes with the body’s ability to fight infections and produce healthy blood cells. Leukemia can be acute (fast-growing) or chronic (slow-growing), and it can affect both children and adults. Early diagnosis and advanced treatments have significantly improved outcomes.

What is Leukemia?

Leukemia is a cancer in which the bone marrow produces abnormal white blood cells that crowd out healthy blood cells.

Types of Leukemia

Acute Leukemia: Rapid onset, requires urgent treatment
Chronic Leukemia: Progresses slowly over time
Lymphocytic Leukemia: Affects lymphoid cells
Myeloid Leukemia: Affects myeloid cells

Causes and Risk Factors

Underlying Cause

Genetic mutations in bone marrow cells

Risk Factors

Exposure to radiation or chemicals (e.g., benzene)
Previous cancer treatment (chemotherapy/radiation)
Genetic disorders (e.g., Down syndrome)
Smoking

Who is at Higher Risk?

Children (acute leukemia)
Older adults (chronic leukemia)
Individuals with weakened immunity

Symptoms

Frequent infections
Fatigue and weakness
Fever or night sweats
Easy bruising or bleeding
Bone or joint pain
Swollen lymph nodes

Warning Signs

Persistent fatigue
Repeated infections
Unexplained bleeding or bruising
Fever without clear cause

Diagnosis

Clinical Evaluation

Medical history and physical examination

Diagnostic Tests

Complete blood count (CBC)
Bone marrow biopsy (key test)
Genetic and molecular tests
Imaging (if needed)

Conditions That May Mimic Leukemia

Severe infections
Anemia
Other blood disorders

Treatment Options

Standard Treatments

Chemotherapy (primary treatment)
Targeted therapy

Advanced Treatments

Immunotherapy
Stem cell (bone marrow) transplant

Supportive Care

Blood transfusions
Infection management
Nutritional support

Complications

Short-Term

Severe infections
Bleeding issues

Long-Term

Organ damage
Recurrence of disease
Side effects of treatment

Prevention Tips

Leukemia cannot always be prevented, but:

Avoid exposure to harmful chemicals
Limit radiation exposure
Maintain overall health

Outlook

The prognosis depends on the type and stage of leukemia. Many forms, especially in children, are highly treatable with modern therapies. Early diagnosis improves survival and quality of life.
