Getting diagnosed with CML
You may have had a routine blood test for something else. And your GP may contact you about an abnormal result. They will arrange to speak to you about this and explain what this means.
It can be hard for GPs to decide who may or may not have cancer. If you have symptoms, your GP may ask you to wait to see if they get better or respond to treatment, such as antibiotics.
The important thing is to go back to your GP if you’re not getting better.

There are guidelines for GPs to help them decide who needs a referral. These vary slightly between the different UK nations. Your GP will use these guidelines as well as their own experience and judgement.
Some of the guidelines have targets around how quickly you are referred. For example, you might have blood tests within 2 days. Or you may see a specialist immediately (within a few hours).
Ask your GP when it is likely you will see a specialist.
Sometimes you might feel that your GP is not concerned enough about your symptoms. If you think they should be more concerned, print this page and the symptoms page. Ask your GP to explain why they don’t think you need a referral.
Contact your GP again if your symptoms don't get better or you notice any new or unusual symptoms.
If your GP suspects you have leukaemia you generally have tests to see a specialist quite quickly. This is usually within a few hours or days. Ask your GP when you should get your appointment and contact them again if you don’t get one. Some hospitals have a referral service you could try contacting if you know which hospital you are going to. Explain that you are waiting for an urgent suspected cancer referral.

Your hospital is working towards waiting time targets. For example, a target to find out whether you have cancer or not. And there are targets to start treatment if you are diagnosed with cancer. These are slightly different depending on where you live in the UK.
