Kidney cancer, if detected early and treated effectively, can potentially have favorable outcomes. However, early-stage kidney cancer often lacks distinct symptoms, leading to misdiagnosis. Symptoms such as hematuria, pain, and palpable masses typically indicate an advanced stage. Therefore, any of these symptoms should be taken seriously. Urine cytology, blood biochemical tests, and ultrasound are quite sensitive for the detection of renal tumors. X-ray images may show a prominent localized contour of the kidney with speckled or incomplete shell-like calcifications. Excretory or retrograde pyelography can reveal compression of the renal pelvis and calyces, showing irregular deformations and possibly filling defects. If necessary, isotope scanning, percutaneous renal biopsy, or fine needle aspiration cytology may be conducted.
