Renal cancer diagnosis
Most kidney tumors are malignant (cancer), but some are benign (not cancer). There are currently no imaging tests that can reliably determine whether a kidney tumor is benign or malignant. If you are diagnosed with a kidney tumor or kidney cancer, it is very important to treat it as early as possible.
Diagnosis of kidney cancer
If you have symptoms of kidney cancer, your doctor will ask you about your health. Your lifestyle, including smoking and drinking habits; Your family medical history; And problems associated with kidney cancer symptoms. Your doctor will order tests to diagnose the problem.
These tests may include:
Blood and urine tests: No blood or urine test can definitively diagnose kidney cancer. These tests can help your doctor diagnose or rule out other possible causes of your symptoms, and can also indicate that you may have kidney cancer.
Imaging tests: These tests will focus on the kidneys, possibly the parts of the body where kidney cancer often spreads, including the lungs, bones, and to a lesser extent, the brain and spine. Imaging tests include:
CT or CAT (computerized axial tomography) scan. This is the most common imaging test for kidney cancer.
Magnetic resonance imaging scans.
Ultrasonic wave
Chest X-ray
Bone scan
Biopsy: A biopsy is when a small piece of suspected cancer tissue is removed and examined under a microscope. This is the only way to definitively diagnose kidney cancer before surgery. The tissue is usually removed by interventional radiologists, who use imaging techniques to guide slender needles to the suspected tumor in a minimally invasive procedure.
