But in most cases, doctors must confirm this by testing a tissue or cell sample and checking it with a microscope (a procedure known as a biopsy). Other diseases, like bone infections, can cause symptoms and imaging results that might be confused with bone cancer.

They help show if the bone cancer has spread to your lungs, liver, or other organs. The scans show the lymph nodes and distant organs where there might be cancer spread.

For this test, you stay on the CT scanning table while a radiologist moves a biopsy needle toward the tumor. Other imaging tests or a bone biopsy may be needed to know what's causing the change.

PET scans use glucose (a form of sugar) that's attached to a radioactive atom. Cancer cells absorb a lot of the radioactive sugar because of their high rate of metabolism.

A biopsy takes a piece of tissue from a tumor so that it can be looked at with a microscope and tested in the lab. It's very important that your biopsy be done by a surgeon with experience in diagnosing and treating bone tumors.

Some kinds of bone tumors can be diagnosed from needle biopsy samples, but larger samples (from a surgical biopsy) are often needed to diagnose other types. Sometimes, the doctor can aim the needle by feeling the tumor if it's near the surface of the body.

Many experts feel that a core needle biopsy is better than FNA to diagnose a primary bone cancer. In this procedure, a surgeon needs to cut through the skin to reach the tumor to remove a small piece of tissue.

If the entire tumor is removed (not just a small piece), it's called an excisional biopsy. These biopsies are often done with the patient under general anesthesia (drugs are used to put you into a deep asleep).

Find out how x -rays are used to help diagnose bone cancer, including what they are, how you have them and what happens afterwards. X -rays use high energy rays to take pictures of the inside of your body.

Unless your doctor thinks it’s urgent the results might take a couple of weeks. You might have contact details for a specialist nurse, and you can ask them for information.

It may help to talk to a close friend or relative about how you feel. For support and information, you can also contact the Cancer Research UK nurses on freephone 0808 800 4040.

The risk of the radiation causing any problems in the future is very small. The benefits of finding out what is wrong outweigh any risk there may be from radiation.

Contrast studies may require more preparation ahead of time and may cause some discomfort and side effects, depending on what kind you are having. Radiographs, most often called x -rays, produce shadow-like images of bones and certain organs and tissues.

They can show some organs and soft tissues, but MRI and CT scans often give better pictures of them. Another contrast study, an intravenous pyelogram (MVP), uses a special dye to look at the structure and function of the urinary system (ureters, bladder, and kidneys).

Tissues in the body absorb or block the radiation to varying degrees. After passing through the body, the beam hits a piece of film or a special detector.

Tissues that block high amounts of radiation, such as bone, show up as white areas on a black background. Soft tissues block less radiation and show up in shades of gray.

You’ll need to remove jewelry or other objects that might interfere with the image. You’ll be asked to sit, stand, or lie down, depending on the body part to be x-rayed.

Contrast studies Angiography: You’ll be asked to not eat before this test. You will lie still on a table as the skin over the injection site is cleaned and numbed.

A tiny cut will be made so the catheter (thin plastic tube) can be put into a blood vessel (usually the artery at the top of the thigh) and slid in until it reaches the area to be studied. Firm pressure might be needed on the catheter site for a while to make sure it doesn’t bleed.

You’ll also need to lie flat and keep your leg still for up to several hours. Magnetic resonance angiography (MRA) is an MRI study of the blood vessels.

Intravenous pyelogram (MVP): You’ll probably be asked not to eat or drink anything for about 12 hours before this test, and you must take laxatives to clean out your bowel. Another series of x -rays is taken over the next 30 minutes or so to get pictures of the dye as it moves through the kidneys and out of your body.

Lower GI series (barium enema): Your diet may be restricted for a few days before this test. Then liquid barium is put into your bowel through a small, soft tube placed in your rectum.

Upper GI series: You will probably be asked to not eat or drink for 8 to 12 hours before this test. You will lie down and be strapped to a tilting table while a series of x -rays are taken as the barium coats your esophagus and stomach.

You’ll need to swallow the barium mixture a few times during the test. You might also be asked to swallow baking soda crystals to create gas in your stomach.

Venography : As you lie still on a table, the skin over the vein to be used is cleaned and numbed. Extra fluids may be given through the catheter to help wash the dye out of your body.

Firm pressure may be needed on the site for a while to make sure it doesn’t bleed. The contrast material may cause nausea, vomiting, flushing, itching, or a bitter or salty taste.

In rare cases, people can have a severe allergic reaction to the contrast material that affects their breathing and blood pressure. There’s also a small risk of damage to the blood vessel from the catheter, which could lead to internal bleeding.

A hematoma (a large collection of blood under the skin) may develop where the catheter was put in if pressure is not kept on the site long enough. Intravenous pyelogram (MVP): The contrast dye sometimes causes some people to have flushing, mild itching, or a bitter or salty taste.

In rare cases, people have a severe reaction to the contrast material and need emergency treatment. Lower GI series (barium enema): The test can be uncomfortable.

The barium contrasts material will make your stools a light color for a few days after the test and may cause constipation. Your arm or leg (where the catheter is put in) may feel numb during the test.

In rare cases, people can have a severe allergic reaction to the contrast material that affects their breathing and blood pressure. There’s also a small risk of damage to the blood vessel from the catheter, which could lead to internal bleeding.

A newer technology, called digital radiology, produces pictures on computer screens rather than on film. The size and contrast of the pictures can be digitally adjusted to make them easier to read, and they can be sent to computers in other medical offices or hospitals.
