Chest x-ray for acute lymphoblastic leukaemia (ALL)

An x-ray is a test that uses small doses of radiation to take pictures of the inside of your body. They are a good way to look at bones and can show changes caused by cancer or other medical conditions. X-rays can also show changes in other organs, such as the lungs.

You usually have x-rays in the imaging department of the hospital, taken by a radiographer. But in an emergency they are sometimes done on the ward.

What happens

Before your x-ray

There is no special preparation for an x-ray. You can eat and drink normally beforehand. Take your medicines as normal.

When you arrive, the radiographer might ask you to change into a hospital gown and take off any jewellery.

During your x-ray

You usually have a chest x-ray standing up against the x-ray machine. If you can’t stand you can have it sitting or lying on the x-ray couch. For x-rays of other areas of the body the best position is usually lying down on the x-ray couch.

The radiographer lines the machine up to make sure it's in the right place. You must keep very still to prevent blurring of the picture.

The radiographer then goes behind a screen. They can still see and hear you. They might ask you to hold your breath for a few seconds while they take the x-ray. 

X-rays are painless and quick. You won’t feel anything.

You might have more than one x-ray taken from different angles. The whole process may take a few minutes.

After your x-ray

After the x-ray you can get dressed and go back to the ward if you are an inpatient. Or back home if your not. 

Getting your results

Ask your doctor when to expect your results and how you will receive them. 

Waiting for test results can be a worrying time. 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 lines are open from 9am to 5pm, Monday to Friday.

Possible risks

An x-ray is a safe test for most people but like all medical tests it has some possible risks. Your doctor and radiographer make sure the benefits of having the test outweigh these risks.

Radiation

The amount of radiation you receive from an x-ray is small and doesn't make you feel unwell.

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.

Talk to your doctor if you are worried about the possible effects of x-rays.
