If you’ve been feeling incredibly tired, losing weight for no clear reason, or hearing mention of chronic myeloid leukemia (CML) after a blood test, you might be feeling a bit overwhelmed. Let’s simplify things.
Chronic myeloid leukemia (CML) is a type of cancer that affects the blood and bone marrow, and it stems from a genetic change called the Philadelphia chromosome.
Some common symptoms to look out for include:
You May Also Like
- Constant tiredness
- Night sweats
- Weight loss without trying
- Fever
- Bruising or bleeding easily
- A feeling of fullness in your abdomen due to an enlarged spleen
- Bone pain
The disease typically progresses slowly and may not show symptoms early on.
While CML is considered rare, research shows Black Americans — especially Black women — experience poorer outcomes compared to other groups. Researchers say earlier diagnosis, consistent care, and strong patient advocacy all play an important role in improving survival.
This means awareness, early testing, and strong support from healthcare providers are even more important for us.

What is Chronic Myeloid Leukemia (CML)?
Chronic myeloid leukemia (CML) — sometimes called chronic myelogenous leukemia — is a type of cancer that originates in the cells that produce blood in the bone marrow. Unlike some other types of leukemia that can progress quickly, CML often develops slowly.
In its early stages, many people don’t even notice any symptoms, and it’s sometimes found during routine blood tests.
The issue starts with a genetic change called the Philadelphia chromosome, which leads to the creation of an abnormal protein known as BCR-ABL.
This protein causes white blood cells to grow uncontrollably. As a result, these bad myeloid cells eventually take over and push out the healthy blood cells.

Chronic Myeloid Leukemia Symptoms: Early and Advanced Signs
Chronic myeloid leukemia (CML) can be hard to spot early on since its symptoms are often quite subtle, according to the Mayo Clinic.
Early Signs for Leukemia in Adults
In the early stages, adults might experience mild fatigue, occasional night sweats, slight weight loss, or feeling full after eating only a small amount.
Many people overlook these signs, thinking they’re just stressed out or getting older. This is why regular blood tests are important for catching any potential issues.
More Noticeable Symptoms of CML Cancer
As chronic myeloid leukemia (CML) advances, you might notice some more severe symptoms, including:
- significant tiredness
- a higher likelihood of getting infections
- easy bruising or bleeding
- unexplained fevers
- a swollen spleen that makes your left abdomen feel full
- bone pain
If you’re searching for “signs for leukemia in adults,” this is what doctors look for, especially when symptoms persist.

What Causes Chronic Myeloid Leukemia?
Chronic myeloid leukemia isn’t caused by anything you might have eaten, stress, or choices you made.
Instead, it stems from a genetic mutation that usually happens after you’re born, not something you inherit from your parents.
According to the American Cancer Society, the process involves a swap of genetic material between chromosomes 9 and 22, leading to what’s known as the Philadelphia chromosome.
This mutation creates a protein called BCR-ABL, which causes your body to produce too many white blood cells.
While researchers are still trying to figure out why this mutation occurs, they have found that exposure to high doses of radiation may increase the risk.

How Is CML Diagnosed?
How does a doctor diagnose chronic myeloid leukemia? If your doctor thinks you might have CML, they’ll start with some tests, as noted by Yale Medicine.
Blood Tests
They often reveal a high white blood cell count, unusual platelet levels, and signs of immature cells in your blood.
Bone Marrow Biopsy
To confirm CML, a bone marrow biopsy is important for both diagnosis and to check how advanced the disease is.
Genetic Testing
Additional genetic testing looks for the Philadelphia chromosome and the BCR-ABL gene, which helps decide if targeted therapy is an option for you.
So when people search “how is CML diagnosed,” the answer is: blood work + bone marrow testing + genetic confirmation.

Treatment for Chronic Myelogenous Leukemia
Treatment for CML has made significant strides over the last 20 years, according to the Leukemia & Lymphoma Society.
1. Targeted Therapy (Tyrosine Kinase Inhibitors – TKIs)
The American Cancer Society explains that targeted drugs, specifically Tyrosine Kinase Inhibitors (TKIs), work by targeting the abnormal BCR::ABL1 protein that contributes to cancer growth. They are effective at stopping its harmful effects.
Some well-known TKIs include Imatinib (Gleevec), Dasatinib (Sprycel), Nilotinib (Tasigna), and Bosutinib.
Many patients find that these treatments can turn CML into a manageable chronic condition, according to the American Cancer Society. This offers hope for a better quality of life.
2. Stem Cell Transplant
Stem cell transplants are usually considered for more advanced cases or when other treatments haven’t worked.
3. Clinical Trials
It’s a good idea to talk to your oncologist about clinical trials, especially if your initial treatment isn’t having the desired effect. Treatment aims to achieve remission, which means having very low or no BCR-ABL gene levels.

The 3 Phases of CML Disease
Chronic myeloid leukemia develops in three stages, according to the Leukemia & Lymphoma Society.
1. Chronic Phase
The first stage, known as the chronic phase, usually doesn’t show significant symptoms or might only produce mild ones. Most people find out they have CML during this phase.
2. Accelerated Phase
In this phase, chronic myeloid leukemia gets worse, and people may feel sicker.
3. Blast Phase (Blast Crisis)
This is the phase of chronic myeloid leukemia where there are a lot of immature white blood cells in the blood and bone marrow. This phase of myeloid leukemia is like acute leukemia, and people need immediate and intensive treatment.
When to See a Doctor
It is important to understand that feeling tired all the time does not necessarily mean you have CML.
You should talk to a doctor if you have symptoms, including:
- Persistent fatigue
- Weight loss that you cannot explain
- Night sweats
- Getting sick very often
- Bruising or bleeding easily
- Feeling full or painful in the stomach area
Seeing a doctor early on is very important.
If you do not feel like the doctor is listening to you, speak up for yourself. Ask the doctor to do some tests. Bring a friend or family member with you to the doctor.

Living With Chronic Myeloid Leukemia
When you find out you have chronic myeloid leukemia, it can be really tough on you. You might feel sad. Your body might feel weak.
The good news is that lots of people with CML are able to live long and happy lives if they get the right treatment.
Here are some things that can help you deal with CML:
- Take your medicine every day like you are supposed to
- Go to the doctor for check-ups all the time
- Eat food that’s good for you
- Get some exercise
- Talk to someone who can help you feel better, like a therapist or someone who has CML
Support groups can be really helpful. Blood Cancer United has some great resources for patients with chronic myeloid leukemia.
