Acute lymphoblastic leukaemia (ALL)
The terms 1 year survival and 5 year survival don't mean that you will only live for 1 or 5 years.
The NHS, other health organisations, and researchers collect information. They record what happens to people with cancer in the years after their diagnosis. 5 years is a common time point to measure survival. But some people live much longer than this.
5 year survival is the number of people who have not died from their cancer within 5 years after diagnosis.
Some of the statistics have to be based on a small number of people. Because this cancer is less common, survival is harder to estimate than for other, more common cancers. Remember, they can't tell you what will happen in your individual case.
There are statistics available for ALL survival in England. But there are no UK-wide statistics for people with ALL that also include Scotland, Wales and Northern Ireland. The figures for 1 year survival are for people diagnosed between 2018 and 2020. The figures for 5 year survival are for people diagnosed between 2014 and 2016.
around 85 out of 100 people (around 85%) will survive their leukaemia for 1 year or more after being diagnosed
70 out of 100 people (70%) will survive their leukaemia for 5 years or more after being diagnosed
This is for all ages. Younger people tend to have a better prognosis than older people.
Statistics for people diagnosed with ALL by age are available from one area of England between 2010 and 2019.
65 out of 100 (65%) will survive their leukaemia for 5 years or more after diagnosis. If you are aged between 15 and 24, your prognosis might be better than this
around 25 out of 100 people (around 25%) will survive their leukaemia for 5 years or more after diagnosis
Your age affects how well leukaemia responds to treatment. Younger people have a better prognosis.
Outlook for ALL depends on other things such as:
what type of ALL you have
if you have a high number of white blood cells in the blood at diagnosis
the changes found in the chromosomes or genes of your cancer cells
if you have leukaemia cells in your spine and brain (central nervous system or CNS)
if your ALL that doesn't go away with treatment. This is called refractory ALL
if your ALL comes back after treatment. This is called relapsed ALL
Some specific genetic abnormalities in your leukaemia cells may make the leukaemia harder to treat successfully. But some changes may make it easier as they might allow treatment to be more targeted.
Your outlook is also affected by how well the leukaemia responds to treatment and how long it takes to go into remission. Remission means that there is no sign of leukaemia in your bone marrow when looked at under a microscope. And the numbers of blood cells have returned to normal.

Acute lymphoblastic leukaemia is a type of blood cancer. It starts from young white blood cells called lymphocytes in the bone marrow.
The main treatment for ALL is chemotherapy. But you may also have a targeted cancer drug, immunotherapy, or a stem cell transplant. Find out how your doctor chooses your treatment, treatment side effects and follow up.
You may find it difficult coping with a diagnosis of ALL both practically and emotionally. Find out about the things you can do and who can help you cope.
We don’t know what causes most cases of acute lymphoblastic leukaemia (ALL). But there are some factors that may increase your risk of developing it. These include certain genetic conditions, previous chemotherapy treatment and ionising radiation.
Read about research into ALL, what clinical trials are and how to take part.
