Chronic Myeloid Leukemia
CML has three phases: chronic, accelerated, and blastic. Your symptoms depend on which phase you are in.
Chronic phase. This is the earliest phase and the easiest to treat. You might not even have symptoms.
Accelerated phase. In this phase, the number of blood cells that don’t work right increases. You're more likely to notice some of these symptoms:
- Being very tired
- Night sweats
- Shortness of breath
- Surprising weight loss
- Appetite loss
- Swelling or pain on your left side (which could be a sign of an enlarged spleen)
- Bone pain
Other symptoms may include stroke, visual changes, ringing in the ears, feeling like you’re in a daze, and prolonged erections.
Blastic phase. This is the most serious CML phase. The leukemia cells grow and crowd out healthy blood cells and platelets.
In this phase, you'll have more severe symptoms, including:
- Skin changes including bumps, tumors
- Swollen glands
- Bone pain
Getting a Diagnosis
If you do have symptoms your doctor will want to know:
- What problems have you been having?
- How long have you been noticing these symptoms?
- Do your symptoms come and go or are they constant?
- What makes you feel better or worse?
- Are you taking any medication?
Your doctor may do more tests to confirm the diagnosis:
- A complete blood count to see how many white blood cells, red blood cells, and platelets you have
- Bone marrow tests to check how advanced the cancer is. Doctors use a needle to take a sample, usually from your hip bone.
- A very detailed lab test of your genes, called fluorescence in situ hybridization (FISH), to measure the number of cells containing the Philadelphia chromosome
- Ultrasound or CT scan to check the size of your spleen. Ultrasounds use sound waves to make images that doctors and other medical professionals can read. A CT, or computed tomography, scan is an X-ray that takes a series of pictures inside your body. These are processed in a computer to create a layered image with lots of detail.
- Another specific lab test called polymerase chain reaction, to look for the BCR-ABL gene. This gene is involved in the process that tells your body to make too many of the wrong kind of white blood cells.
