Wilms Tumor

Wilms tumor is a rare type of kidney cancer. It causes a tumor on one or both kidneys. It usually affects children, but can happen in adults. Having certain genetic conditions or birth defects can increase the risk of getting it. Children that are at risk should be screened for Wilms tumor every three months until they turn eight.

Symptoms include a lump in the abdomen, blood in the urine, and a fever for no reason. Tests that examine the kidney and blood are used to find the tumor.

Doctors usually diagnose and remove the tumor in surgery. Other treatments include chemotherapy and radiation and biologic therapies. Biologic therapy boosts your body's own ability to fight cancer.

X-Rays

What is an x-ray?

X-rays are a painless medical imaging test. They send a small amount of radiation through your body to create pictures of bones and organs.

X-rays are a type of electromagnetic radiation. They create images in shades of black, white, and gray because different tissues absorb radiation differently. Bones absorb the most radiation and appear white. Fat and other soft tissues absorb less and appear gray. Air absorbs the least radiation, so areas like the lungs appear black.

The image is recorded on film or sent to a computer. Health care providers use x-rays to find health problems and to check how well certain treatments are working.

Who needs an x-ray?

X-rays are commonly used to check for fractures (broken bones). They are also used for other purposes. For example, chest x-rays can detect pneumonia. Mammograms use x-rays to look for breast cancer. X-rays are also used as part of other imaging tests, such as CT scans.

How do you prepare for an x-ray?

In most cases, little or no preparation is needed. You may be asked to wear a lead apron to protect certain parts of your body. You may also be asked to remove jewelry or other items that could affect the image.

The amount of radiation from an x-ray is small. For example, the radiation from a chest x-ray is about the same as the natural radiation you are exposed to from the environment over about 10 days.

Always tell your provider if you are pregnant or think you may be pregnant.

How is an x-ray done?

Depending on the part of your body being examined, you may be asked to stand, sit, or lie down. You will need to stay still for a short time while the image is taken.

What should you expect after an x-ray?

After an x-ray, you can return to normal activities right away. A specialist called a radiologist reviews the images and shares the results with your provider.
