During palpation for suspected Wilms tumor in a child, what is the key precaution to prevent tumor rupture?

• A. Palpate vigorously to determine size
• B. Avoid palpation entirely
• C. Palpate gently and avoid rupturing the tumor
• D. Do not inform parents of suspicion

Answer: (C)

The main idea is to handle the suspected Wilms tumor with care to prevent rupture. Wilms tumors are often encapsulated renal masses in children; if the capsule is disrupted, tumor cells can spill into the peritoneal cavity. This spillage can seed tumor cells, upstage the disease, and worsen prognosis, making surgical removal and subsequent therapy more challenging. Because of that, the safest approach during examination is to palpate the abdomen very gently and avoid any manipulation that could rupture the tumor. If imaging is available, it should guide the evaluation, and when palpation is performed, pressure should be minimal, with careful, light touch rather than deep or forceful palpation. This gentle technique reduces the risk of rupture while still allowing some assessment of the mass.
