This page from Cancer Australia gives an overview of kidney tumours. Kidney tumours may also be referred to as renal tumours. The overview includes symptoms, treatment, diagnosis and support services available.
The most common type of kidney tumour in children is called Wilms tumour (also known as nephroblastoma). According to the US American Cancer Society, nine out of ten kidney cancers in children are Wilms tumours. Most are unilateral, meaning they only affect one kidney. Though a single tumour is most common, 5-10% of children with Wilms tumour may have more than one tumour in the same kidney. Only 5% of children with Wilms tumours have bilateral disease (tumours in both kidneys). You may also want to read more information about renal tumours from the US National Cancer Institute.
Though Wilms tumour is the most common kidney cancer affecting children, there are other types of kidney tumours in children including:
- clear cell sarcoma of the kidney
- malignant rhabdoid tumour of the kidney
- mesoblastic nephroma
- renal cell carcinoma.
These tumours are all rare cancers, so you may wish to look at other resources on Cancer Advisor for families facing rare cancers. It may also help to read personal stories from other families who have had a child or young person diagnosed with a kidney cancer.
