Chronic myeloid leukaemia (CML) is a type of cancer that affects the blood and bone marrow. It usually develops very slowly. 

Many people with chronic myeloid leukaemia (CML) won't have any symptoms at all. Some of the common symptoms can include feeling full or tummy discomfort, swollen lymph nodes , feeling weak and weight loss.

You usually start by seeing your GP if you have symptoms that could be due to CML. Or your GP might arrange to see you if you have had an abnormal blood test result. They will then decide whether to refer you for further tests or to see a specialist. 

Survival for chronic myeloid leukaemia (CML) depends on several factors including age. These figures can only give you a general guide about survival for CML.

Targeted cancer drugs called tyrosine kinase inhibitors (TKIs) are the main treatment for CML. Find out more about your treatment options, the different treatments and how they monitor treatment is working. 

There are 2 systems to describe how far your CML has developed. You might have 2 or 3 phases. At the moment CML is mainly described using 3 phases. These are chronic, accelerated and blast. Knowing the phase helps your doctor decide which treatment you need.
