Computed tomography can also show the involvement of surrounding lymph nodes, as well as, metastasis to other areas of the body. Magnetic resonance imaging is another test that shows full visualization of a Wilms' tumor. MRI may sometimes be preferred over CT because it does not use ionizing radiation. Wilms' tumor is very treatable, especially in the early stages. Treatment for Wilms' tumor includes surgery, chemotherapy, and possibly radiation therapy.
Surgery is normally the first part of the treatment.
In most cases, the affected kidney is removed. Lymph nodes around the kidney may also be removed. After the surgery, most patients undergo chemotherapy. The length of chemotherapy differs depending on the severity and stage of the tumor. Radiation therapy, specifically brachytherapy is sometimes used in treatment of more advanced cases of Wilms' tumor.
