There are 76 different types of childhood cancers  in total. These types can be grouped into 12 broad categories.
These categories include: Leukaemias, brain and spinal tumours, lymphoma, soft tissue sarcomas, neuroblastoma, renal tumours, bone tumours, germ cell tumours, retinoblastomas, other carcinomas and melanomas, liver tumours and others.
Leukaemia is the most common childhood cancer in the UK forming 30% of cases.
Brain and spinal tumours are the second most common diagnosis forming 27% of cases.
Solid tumours form 60% of cases of childhood cancers, therefore a GP is more likely to see a child with a solid tumour than a child with leukaemia.
This is why it is so important for clinicians and parents to be aware of the symptoms and signs.
