Many people don’t have any symptoms when they're diagnosed with CML. It's often found when a person has blood tests done for another reason and the tests show too many white blood cells. If CML does cause symptoms, they can include:
Feeling very tired (fatigue)
Pain or a sense of fullness in the left upper belly (abdomen), from an enlarged spleen
Feeling full after eating only a small amount
Bleeding or bruising easily
Bone or joint pain
Many of these symptoms can be caused by other, more common health problems. In fact, most of them are more likely to be caused by something else. But it's important to see your healthcare provider if you have these symptoms. Only a healthcare provider can tell if you have CML, another type of cancer, or some other health problem that needs to be treated.
