In children under six years, it may be necessary to remove tissue from the tumor using a needle. The reason for this is that the scans can be difficult to distinguish between Wilms' tumor and a less dangerous cancer called nefroblastomatose. Woven examined microscopically, the diagnosis can be made.
Treatment of Wilms' tumor
