Kidney Tumor Symptoms and Diagnosis

Symptoms of Kidney Tumors

Here are some common symptoms of kidney tumors. These are symptoms of Wilms tumors as well as other types of kidney tumors in children. The same symptoms can also be caused by other problems that are not cancer. So it's important for a child with symptoms like these to see a doctor to find out the cause.

If your child has a kidney tumor, you may notice these symptoms:

  • A lump in the abdomen
  • Pain in the abdomen
  • Blood in the urine

Kidney Tumor Diagnosis

In many cases, the child or teen, family and doctor do not know about the mass until it has grown large - sometimes even larger than the kidney itself.

Most of the time Wilms tumor and clear cell carcinoma have not yet spread to other sites in the body. Other types of kidney tumors are more likely to have spread, but in most cases they have not.

To find out whether your child has a kidney tumor, your child's doctor start with a thorough exam and ask about your child's health background.

Next the doctor will do a series of tests to look for signs of disease. Common tests to check for kidney tumors include:

Blood tests

Used to look at the levels of white and red blood cells and for substances that suggest whether the kidneys are working well.

Urine tests

Used to look for blood and other substances.

Your child's doctor may also want your child to have pictures taken of the inside of her body, such as an X-ray, ultrasound , CT (computed tomography) scan or MRI (magnetic resonance imaging) .

These are called imaging studies, and they allow the doctor to look for tumors or areas of cancer activity.
