Malignant neoplasm of the kidney Hypernephroma Wilms' tumour
Nature:
Adult kidney cancer has no known cause and may be discovered incidentally through examinations for other conditions. It is often widespread when initially found. Recent scientific understanding points to a genetic cause, more so than other cancers.
Incidence:
Childhood kidney cancer, know as Wilm's tumour, occurs primarily in children younger than seven. At least 30 percent of Wilm's tumour cases are caused by inherited factors.
