Wilms Tumor
Wilms tumor is a rare type of childhood kidney cancer that primarily affects infants, toddlers, and young children, most commonly before the age of five. Also known as nephroblastoma, Wilms tumor develops when immature kidney cells grow abnormally and form a tumor within one or both kidneys.
The tumour grows on the kidney with the most common symptom being a sudden swollen stomach. Eventually the tumor becomes much bigger than the kidney itself and both usually require removal. Later stage Wilms can spread to other parts of the body including the lungs, liver and bones.
Wilms is the #1 Childhood Kidney Cancer
& 4 most common Childhood Cancer overall
