Chronic lymphocytic leukaemia (CLL)
CLL is a slow-growing blood cancer that may not need treatment at first. When it does need treatment, there are many effective drugs that can keep the CLL under control.
What is CLL?
CLL is a chronic (slow growing) blood cancer that affects cells called lymphocytes. When you have CLL, your body makes abnormal lymphocytes that grow too fast.
Prognosis for CLL
CLL can't usually be cured, but it can be treated so you can continue to have a good quality of life.
CLL symptoms and diagnosis
Many people with CLL are diagnosed after a routine blood test and won't haven’t noticed any symptoms, but others do.
Testing for CLL
You’ll have tests before and after diagnosis to confirm that you have CLL, monitor it, and monitor any treatment you may need.
CLL treatment and side effects
When treatment is needed, you will be offered options that are right for you and your situation.
Active monitoring (watch and wait)
Some people with CLL won't need treatment straight away, or even for months or years. This is called active monitoring, or watch and wait.
CLL and infection
CLL affects your immune system, so even if you don’t need treatment, you’re more likely to get infections.
Clinical trials
You may be able to join a clinical trial as part of your treatment for CLL.
