Nephroblastoma or Wilms Tumor
Nephroblastoma (or) Wilms tumor is a rare kidney cancer that is highly treatable. Most kids with Wilms tumour survive and go on to live normal, healthy lives. Also known as nephroblastoma, Wilms tumour can affect both kidneys, but usually develops in just one. Before being diagnosed with Wilms tumour, most children do not show any signs of having cancer, and usually act and play normally. Often, a parent discovers a firm, smooth lump in the child's abdomen (belly). It is not uncommon for the mass to grow quite large before it is discovered. In fact, the average Wilms tumour is 1 pound at diagnosis.
