Diagnosis
If a patient has symptoms that suggest kidney cancer, the doctor may perform
one or more of the following procedures:
Physical exam: The doctor
checks general signs of health and tests for fever and high blood pressure.
The doctor also feels the abdomen and side for tumors.
Urine tests: Urine is
checked for blood and other signs of disease.
Blood tests: The lab
checks the blood to see how well the kidneys are working. The lab may check
the level of several substances, such as creatinine. A high level of
creatinine may mean the kidneys are not doing their job.
Intravenous pyelogram
(IVP): The doctor injects dye into a vein in the arm. The dye travels
through the body and collects in the kidneys. The dye makes them show up on
x-rays. A series of x-rays then tracks the dye as it moves through the kidneys
to the ureters and bladder. The x-rays can show a kidney tumor or other
problems.
CT scan (CAT scan): An
x-ray machine linked to a computer takes a series of detailed pictures of the
kidneys. The patient may receive an injection of dye so the kidneys show up
clearly in the pictures. A CT
scan can show a kidney tumor.
Ultrasound test: The ultrasound device uses sound
waves that people cannot hear. The waves bounce off the kidneys, and a
computer uses the echoes to create a picture called a sonogram. A solid tumor
or cyst shows up on a sonogram.
Biopsy: In some cases,
the doctor may do a biopsy. A biopsy is the removal of tissue to look for
cancer cells. The doctor inserts a thin needle through the skin into the
kidney to remove a small amount of tissue. The doctor may use ultrasound or
x-rays to guide the needle. A pathologist uses a microscope to look for cancer
cells in the tissue.
Surgery: In most cases, based on the results of the CT
scan, ultrasound, and x-rays, the doctor has enough information to recommend
surgery to remove part or all of the kidney. A pathologist makes the final
diagnosis by examining the tissue under a microscope.

My kidney cancer was discovered when I had an ultrasound to determine the due date of my baby. They were looking at the baby and found a tumor that had taken over one kidney. I had no symptoms. I'd had an ultrasound with my previous son only six months before and there was no evidence of a tumor. Within a few weeks, I had my kidney removed and was fortunate enough that I did not require additional treatment, and was able to continue on with my pregnancy. I now have an amazing little boy who saved my life.

I am a four-year dialysis patient. Two months ago, my nephrologist ordered a kidney scan. The results showed a tumor on my left kidney; I was told it was cancer. No biopsy has been taken, and I have doubts. My doctor said if it was not cancer it would have some kind of drainage in it. He sent me to another nephrologist, who bluntly said I have kidney cancer by looking at my scan. I am not satisfied about this matter. Thus far, I have no pain, and I can't be put to sleep due to a high allergy to anesthesia. I need advice. I have dialysis every Monday, Wednesday, and Friday year round.
