Tests for breast cancer
You usually have a number of tests to check for breast cancer. This includes:
- a breast examination
- taking a sample of tissue from your breast called a biopsy
Tests your GP might do
Most people with symptoms that could be due to breast cancer start by seeing their GP. Your GP will examine your breasts and might also feel the
Your GP might also ask about your family history. If you have a strong family history of cancer, there might be a faulty
Breast cancer screening
Some women do not have any symptoms and are referred to a breast clinic for tests if their screening mammogram shows an abnormal area.
Tests you might have during your breast clinic appointment
Depending on your symptoms, your GP might refer you to a breast clinic. This is usually a one stop clinic where you have several tests during one visit. It is also called a triple assessment.
The tests you have can diagnose breast cancer and other breast conditions. These might include:
- breast examination
- breast ultrasound scan
- a breast biopsy
A mammogram is an x-ray of your breasts. X-rays use high energy rays to take pictures of the inside of your body. It usually only takes a few minutes.
You need to remove your clothes from the waist upwards and put on a hospital gown. A health professional who specialises in taking mammograms (a mammographer) helps position your breast between the 2 plates on the machine. The plates press your breast firmly for a few moments. This is likely to be uncomfortable or painful, but it is over quickly.
Talk to your radiographer if you are nervous or embarrassed. Or if you are finding the mammogram too painful. They can stop at any time and try to make you more comfortable.
Breast ultrasound scan
A breast ultrasound is a test that uses high frequency sound waves to create a picture of the inside of the breast. A specialist called a sonographer puts some gel over your breast. This can feel cold. They then use an ultrasound probe to slide over the skin and give a clear picture on a screen.
A breast ultrasound usually takes about 10 to 15 minutes. You might feel a little pressure when the sonographer moves the probe over your breast.
A breast biopsy means taking samples of tissue from an abnormal area. It is the only way to find out if you have breast cancer or another breast condition. The results from your mammogram and ultrasound help your doctor know where to take the biopsy from. It also helps your doctor decide the type of biopsy you need.
Your doctor sends the samples to a laboratory and a
There are different types of breast biopsy:
- needle biopsy
- fine needle aspiration
- punch biopsy
- vacuum assisted biopsy
- wire guided excision
The type of biopsy you have depends on a number of factors including how big the suspicious area is and where it is. Your doctor will tell you which type of biopsy you need.
Tests on your breast cancer cells
After a breast biopsy, a sample of cells is sent to the laboratory. A pathologist looks at the samples under a microscope. The results usually take about 2 to 4 weeks.
The pathologist does various tests on the cells. The tests can:
- diagnose breast cancer
- show which type of breast cancer you have
- look for proteins on the surface of the breast cancer cells
- look at cancer genes to find out how active they are. These are called tumour profiling tests such as oncotype Dx test
What tests do I need after a biopsy?
If you have a biopsy that shows that you have breast cancer, you might have more tests to work out where and how big the cancer is. This is called staging the cancer.
The tests you may have include:
- checking for cancer cells in the lymph nodes in your armpit
- blood tests
- MRI scan
- CT scan
- PET-CT scan
- bone scan
Checking for cancer cells in the lymph nodes of your armpit
Breast cancer cells can sometimes spread into the lymph nodes under the arm (the axilla). To check for this, you may have an axilla lymph node ultrasound and biopsy.
The ultrasound scanner has a microphone that gives off sound waves. The sound waves bounce off the organs inside your body, and the microphone picks them up. The microphone links to a computer that turns the sound waves into a picture on the screen.
If there are any areas that look abnormal, doctors can use the ultrasound to guide a needle and take a sample of cells.
Blood tests can check your general health, including how well your liver and kidneys are working. Doctors can also check the number of
Breast MRI scan
MRI stands for magnetic resonance imaging. It uses magnetism and radio waves to take pictures of the inside of the body.
An MRI scan can tell your doctor:
- where the cancer is and how big it is
- whether it has spread to the lymph nodes
It can also help doctors see the cancer better if it doesn’t show up well on a mammogram or breast ultrasound.
CT (or CAT) scan stands for computed (axial) tomography. It is a test that uses x-rays and a computer to create detailed pictures of the inside of your body.
You may have a CT scan to find out whether the cancer has spread to other parts of the body.
A PET-CT scan combines a CT scan and a PET scan. The PET scan uses a mildly radioactive drug to show up areas of your body where cells are more active than normal.
You might have a PET-CT scan to find out if breast cancer has spread to other parts of the body.
A bone scan shows up changes or abnormalities in the bones. You might have a bone scan to find out if breast cancer has spread to the bones.
Liver ultrasound scan
You might have a liver ultrasound scan if you have symptoms that could be due to breast cancer spreading to the liver.
The tests you have helps your doctor find out if you have breast cancer and how far it has grown. This is the stage of the cancer.
This is important because doctors recommend your treatment according to the stage of the cancer.
