Q | do you biopsy the kidney to confirm cancer?
A | Using CT guidance, a small needle can be introduced into the kidney to remove a small sample of the kidney growth. This can be looked at under the microscope to confirm if a renal cancer is present.
The main problem with this particular biopsy is that there is a risk of the renal cancer tracking down the needle path converting a localised cancer to one that can spread.
For this reason the risks and benefits of biopsy of suspicious lesions has to be discussed fully with the patient prior to proceeding.
