To diagnose kidney cancer, your doctor will ask about your symptoms, examine you, may test a sample of your urine with a 'dipstick' to look for blood and infection and take a blood sample. You may be referred to a urologist for further tests, which may include an ultrasound scan and an intravenous pyelogram(IVP urogram) to examine your urinary system. A dye is injected into a vein and removed from your bloodstream by your kidneys as part of urine production. By taking x-ray images while your kidneys are excreting the dye, your doctor can see any abnormalities in the outline of your urinary system. Additional tests:CT scan; an MRI scan. Your doctor may also use an ultrasound or CT scan to guide a needle to your kidney and take a biopsy, a small sample of tissue taken for testing.
