If a patient has symptoms that suggest kidney cancer, the doctor may perform one or more of the following:
Physical examination: A doctor checks general signs of health and tests for fever and high blood pressure. The doctor feels upset and half of tumors.
Urine samples: urine checked for blood and other signs of disease.
Blood tests: The laboratory control of the blood to see how the kidneys. The laboratory may verify the level of various substances such as creatinine. A high creatinine level may mean the kidneys are not doing their job.
Intravenous urography (IVP): The doctor injects dye into an arm vein. The dye travels through the body and accumulates in the kidneys. The contrast makes the display on radiographs. A series of x-ray clues, and the dye moves through the kidneys, ureters and bladder. X-rays can show a kidney tumor or other problems.
Computed tomography (CT): 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 to the kidneys clearly seen in the images. A CT scan can show a kidney tumor.
Ultrasound: The ultrasound device uses sound waves that people can not 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, which shows a sonogram.
Biopsy: In some cases, the doctor may perform a biopsy. A biopsy is the removal of tissue 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 detect cancer cells in tissues.
Surgery: In most cases, is based on the results of computed tomography, ultrasound and x-rays that the doctor has enough information to recommend surgery to remove part or all of the kidneys. A pathologist made the final diagnosis by examining tissue under a microscope.
