Kidney Cancer Patients Often Ask: Surgery Without Biopsy?

The kidney is a vital organ that filters waste from the body and regulates fluid and electrolyte balance. Kidney cancer refers to malignant tumors originating in the renal parenchyma, most commonly renal cell carcinoma. Often called the "silent cancer," kidney cancer frequently shows no symptoms until significantly advanced. Recently, more cases are being discovered incidentally during health screenings through ultrasound or computed tomography (CT) scans. Early detection of kidney cancer offers high chances of complete cure. When tumors are relatively small and confined to the kidney, partial nephrectomy—removing only the cancer while preserving the kidney—is preferred over total kidney removal.
