Some parents of children with cancer may want to know the survival rates for their type of cancer. Others may not find the numbers helpful, or may even not want to know them. Whether or not you want to read about survival rates is up to you.

The survival rate for children with Wilms tumor varies with the stage of the tumor. It also depends on the histology of the tumor cells (how they look under a microscope). Ask your doctor to explain the stage and the histology of your child's cancer.

The 4-year survival rate refers to the percentage of children who live at least 4 years after their cancer is found. Of course, many children live much longer than 4 years (and many are cured).

In order to get 4-year survival rates, doctors have to look at children who were treated at least 4 years ago. Improvements in treatment since then may result in a better outlook for children now being diagnosed with Wilms tumors. Also, some of these numbers are based on only a small number of cases, so their accuracy is not certain.

While statistics give an overall picture, keep in mind that every child's situation is unique and the numbers can't predict exactly what will happen. Talk with your cancer care team if you have questions; they know your child's situation best.
