Many of the
kidney cancer diagnoses are often made during imaging studies which performed
for another health problem.
Apart from that,
the process of requesting diagnostic tests that specific to kidney cancer,
usually occurs when signs and symptoms related to the tumor come to exist.
Some of the
diagnostic tests that physicians ask for when they suspect kidney cancer, are
helpful for kidney cancer diagnosis in general manner, while others confirm the
diagnosis of kidney cancer specifically.
General Health Tests
health tests are the first and most fundamental step in the kidney cancer diagnosis.
At this stage, the doctor questions your medical and family history, also
performs the physical examination.
medical history includes all of the health events in your life and the
medicines that you take. Doctor will question any symptoms which you have and your
health status at this stage.
b. Family History
It is known
that some diseases show familial transition. Therefore, your doctor will want
to know what diseases your family members have and what age that they are
diagnosed with these diseases.
usually evaluates your health status with medical history and physical
examination. At this stage, signs such as infection and bleeding may be
detected due to any health problems.
tests can simply be defined as taking pictures inside of your body. These tests
are often used to confirm the kidney cancer diagnosis. If there is a tumor in
the kidney, it can be scanned by imaging investigations.
a. CT scan
CT scan uses
x-ray rays to display the inside of your body. Images obtained by x-rays sent
from many different angles are combined with a computer. When your doctor
suspects of kidney cancer diagnosis, usually asks CT scan of abdomen or belly,
which is the most accurate test, to confirm the diagnosis.
b. MRI scan
The MRI device uses the magnetic field and radio waves to display your body. Therefore, no x-ray is sent to your body. Your doctor may be asking an MRI scan which is particularly successful option to show the soft tissues such as kidney, when the CT scan cannot be used because of some health conditions.
uses the sound waves for imaging of inside your body. If you have any renal tumor
in your kidneys, it can be detected during this imaging method.
involves the insertion of a thin tube-shaped device into your body and the taking
the images of the inside of your body. Ureteroscopy is not actually used
for the kidney cancer diagnosis. However, if your doctor suspects any Transitional
Cell Carcinoma (TCC) or bladder cancer, may ask for this method of investigation.
usually asks blood tests to investigate the signs of a health problem or to
assess your overall health. These tests do not confirm the kidney cancer diagnosis,
but abnormal results may be indicative of a problem with your kidneys.
blood count (CBC)
CBC covers the measurement of all cells and components in your blood. Due to, one of the functions of the kidney is stimulation of Red Blood Cell production, abnormalities in CBC result can be seen in kidney cancer patients.
Blood chemistry tests are used to measure the amount of chemicals in your blood. As the main function of the kidneys is to filter out harmful waste and chemicals in the blood, the level of chemicals will increase in any disease in the kidneys. For this reason, your doctor may request this test to see if this condition present.
may ask for urine tests to see if there are any problems. Although the results
of urine tests do not confirm the kidney cancer diagnosis, abnormal results
indicate that there is a problem in the kidneys.
is examination of your urine with both microscope and chemical tests. If there is
an amount of blood in your urine which cannot be seen with naked eye, this test
will reveal that. Identifying the blood in urine is an important step for kidney
cytology is the process of examining the urine with microscope to see if there
is any cancer cell.
involves taking samples from your body in order to determine the presence or
absence of any pathology.
Biopsy is the only way to confirm the diagnosis of many of the cancers. But the situation for the kidney cancer diagnosis is different. Diagnosis of kidney cancer is mostly can be achieved by imaging studies. Therefore, biopsy is rarely needed in renal tumors.
