Wilms tumor occurs in which organ?

Wilms tumor occurs in which organ?

• A. Kidney
• B. Liver
• C. Brain
• D. Lungs

Answer: (A)

Wilms tumor is a nephroblastoma, a cancer that originates in the kidney and is most common in young children. Because it arises from primitive kidney tissue, the organ involved is the kidney. Clinically, it often presents as a unilateral, non-tender abdominal mass and may be associated with hypertension due to increased renin production. Distinguishing it from tumors of other organs—like the liver, brain, or lungs—hinges on its renal origin. Treatment typically involves surgical removal of the kidney with the tumor (nephrectomy), followed by chemotherapy and sometimes radiation, depending on the stage.
