If you are suspected with a kidney cancer, you may have following tests to check your kidney cancer:
Ultrasound: Ultrasound uses high-energy rays to draw the picture of internal parts of the body (such as kidney, bladder) on the computer screen.
CT Scan (Computerized Tomography) or MRI (Magnetic Resource Imaging): CT scans produces more detail picture on computer screen. MRI generates cross sectional picture on computer screen.
Biopsy: In this test, doctor removes some cells from the suspected area and examine under a microscope to check the cancerous cells. Doctor avoids the biopsy because it has side effects such as infection, bleeding and risk to spread the cancer
