What further tests might I have?
Following a diagnosis of breast cancer, further tests or investigations will be performed.
Because breast cancer can spread to other parts of the body, these tests will check for this. They will also help your breast care team gather as much information as possible about your breast cancer so that they can decide on the best possible treatment for you.These further tests may include:
- Photographs
- Blood tests
- X-rays
- Bone scan
- Ultrasound scan
- MRI (Magnetic Resonance Imaging) scan
- CT (Computerised Tomography) scan
- Other investigations

X-rays
Bone scan
Before the scan an injection of an isotope (a radioactive substance) is given into a vein in the arm. The dose of radiation is very small and not harmful.
It does not make you radioactive; you are safe to be with other people afterwards (although try to avoid pregnant women and children for the day if you can) and the radioactivity will disappear from your body within a few hours.
A bone scan uses this radiation to identify bone disease. Abnormal bone will absorb more of the radioactive substance than normal bone and will show up on the scan as highlighted areas.
If you have arthritis or a previous injury, these will also show up on the scan and you may be asked to have additional x-rays of any highlighted areas (hot spots) to rule out other causes.
The isotope takes up to 3 hours to travel through the bloodstream to the bones before the scan can be taken. You may want to prepare for this waiting time by bringing a book with you or bringing a friend or relative for company.
The scan itself takes around 30 minutes under a special camera. It is painless.
Ultrasound scan
This test is done in the hospital's scanning department. You are asked to lie on an examination couch and a gel is spread over the skin. This helps to conduct the sound waves.
A special sensor, similar to a microphone, is moved over the skin. This transmits sound waves, some of which are bounced back and some are absorbed. The returning sound waves are picked up, converted into an image using a computer and displayed on a screen.
MRI (Magnetic Resonance Imaging) scan
Computer systems and radio waves are used but no radiation. Views can be taken from nearly every angle, allowing the doctor to build up a very detailed picture of the tumour.
This test is done in the hospital's scanning department. You are asked to lie very still on a couch inside a long chamber for up to 30 minutes. This can be quite unpleasant if you are claustrophobic and you may want to mention this to the radiographer so that he/she will be aware of your discomfort.
As the MRI scanner is very noisy you will be given earplugs/headphones and these may serve as a useful distraction. The scan itself is painless.
The chamber is a powerful magnet, so before going in you will be asked to remove any metal belongings, such as your wristwatch. If you have a cardiac monitor, a pacemaker or certain surgical clips you should not have an MRI scan because of the magnetic fields.
You will be able to go home once the scan has been completed.
CT (Computerised Tomography) scan
The scan itself uses a small amount of radiation. It is a painless procedure that should take anywhere from 10-30 minutes. You will be asked not to eat or drink for the 4 hours before the scan.
Sometimes, a drink or dye injection may be given to help illuminate a particular area more clearly. If this is something that you come across, make sure that you let the doctors know if you have asthma or are allergic to iodine.
