Symptoms of childhood acute lymphoblastic leukaemia (ALL)
Childhood cancer is rare. Most children with one or more of these symptoms don't have leukaemia. But it's important to get your GP to check any of the symptoms out.
Many symptoms of ALL are vague and non specific. They are similar to the symptoms of many more minor childhood illness.
Symptoms of childhood ALL can include:
- looking pale
- feeling very tired
- bruising or bleeding easily or for no reason
- having a high temperature (fever)
- picking up infections easily and often
- swollen
lymph nodes - bone pain
- loss of appetite
- swollen tummy (abdomen)
- swelling of one or both testicles
Not every child with ALL has all of these symptoms before they are diagnosed.
At the beginning these symptoms might come and go. Your child might be exhausted one day, but brighter the next.
Most of these symptoms are due to the leukaemia cells having spread inside the

Bone pain
Your child might have bony pain. Children might limp or refuse to walk as they would normally. This pain is most common in the long bones in the body, like the arms or legs. But it can also affect the back and joints.
Loss of appetite
Your child might go off their food. They might be eating smaller amounts or not wanting to eat even their favourite foods. This is very common in childhood. Remember, this does not necessarily mean your child has leukaemia.
Feeling full in the tummy (abdomen)
Your child might have a feeling of fullness or discomfort in their tummy (abdomen). Your child’s tummy might look bigger than normal, or you might notice they suddenly jump a nappy or trouser size.
This can happen if their liver or spleen are swollen.

Irritability
Your child might seem particularly fractious or irritable and you might be finding it difficult to get them to settle.
Symptoms if the leukaemia has spread to the fluid around the brain or spinal cord (CNS)
The brain and spinal cord make up the central nervous system (CNS). Cerebrospinal fluid (CSF) is the name of the fluid that surrounds the brain and spinal cord. Some children at diagnosis have leukaemia cells that have spread to the CSF. Symptoms of this spread might mean your child:
-
has headaches
-
is having more difficulty with school work
-
is feeling generally weak
-
has had unexplained vomiting
-
has blurred vision
-
has seizures (fits)

It can be a medical emergency.
When to see your GP
Take your child to see their GP if you notice a change that isn't normal for them or if you have any of the possible signs and symptoms of leukaemia.
There are guidelines for GP’s to follow so they know when to refer a child to a specialist. The guidelines are clear that parent or carer concern about any changes should be taken into account.
