Understanding Chronic Myelogenous Leukemia (CML): Symptoms, Diagnosis, and Treatment Options

Chronic Myelogenous Leukemia (CML), also known as Chronic Myeloid Leukemia, is a type of blood cancer that affects the bone marrow, where blood cells are made. CML usually develops in middle-aged or older individuals and progresses gradually. With proper treatment, many people with CML can achieve remission, a state where the cancer is less active than before.

Causes and Risk Factors

In most cases, the exact cause of CML is unknown. It is not typically inherited from parents or caused by infections, smoking, or diet. The only known risk factor is exposure to high levels of radiation.

Symptoms of CML

CML has three phases: chronic, accelerated, and blastic. Symptoms may vary depending on the stage of the disease.

Chronic Phase Symptoms:

• Fatigue

• Weight loss

• Fever

Accelerated Phase Symptoms:

• Increased fatigue

• Fever

• Bruising

• Night sweats

• Shortness of breath

• Swelling or pain on the left side (enlarged spleen)

• Bone pain

Blastic Phase Symptoms:

• Infections

• Bleeding

• Skin changes (bumps, tumors)

• Swollen glands

• Bone pain

Diagnosing CML

If you experience symptoms of CML, your doctor will perform a physical examination and may order the following tests:

• Complete blood count (CBC)

• Bone marrow test

• FISH test (fluorescence in situ hybridization)

• Ultrasound or CT scans

• Polymerase chain reaction (PCR) test

Treatment Options for CML

The goal of CML treatment is to destroy leukemia cells and restore healthy blood cell levels. Treatment options include:

• Tyrosine kinase inhibitors (TKIs): Bosutinib (Bosulif), Dasatinib (Sprycel), Imatinib (Gleevec), Nilotinib (Tasigna)

• Chemotherapy

• Biologic therapy (interferon)

• Stem cell transplant

Your doctor will develop a personalized treatment plan based on the phase of your CML and your overall health. It's essential to follow your treatment plan, eat a healthy diet, and exercise when you feel up to it.

Living with CML: Support and Self-Care

Living with CML can be challenging, but you don't have to face it alone. Reach out to family and friends for emotional support, and consider joining a support group to connect with others who have CML. The Leukemia & Lymphoma Society offers valuable resources, including information on treatment, support services, and help for caregivers.

Remember, many people with CML live long lives with proper treatment and care. Work closely with your healthcare team, and don't hesitate to ask questions or seek a second opinion if needed.
