How is breast cancer diagnosed?
Initial assessment
If you develop a lump or symptoms which may be breast cancer, a doctor will usually examine your breasts and armpits (axillae) to look for any lumps or other changes. You will normally be referred to a specialist. Sometimes a biopsy of an obvious lump (see below) is arranged, but other tests may be done first such as:
- Mammogram. This is a special X-ray of the breast tissue which can detect changes in the density of breast tissue which may indicate a tumour.
- Ultrasound scan of the breast.
- MRI scan of the breast. This is more commonly performed on younger women, especially those with a strong family history of breast cancer.
A biopsy is when a small sample of tissue is removed from a part of the body. The sample is examined under the microscope to look for abnormal cells. A specialist may take a biopsy with a needle which is inserted into the lump and some cells are withdrawn. Sometimes the doctor may be guided as to where to insert the needle with the help of a mammogram or ultrasound scan. Sometimes a small operation is needed to obtain a biopsy sample.
The biopsy sample can confirm or rule out breast cancer. Also the cells from a tumour can be assessed and tested to determine their grade and receptor status (see above).
Assessing the extent and spread
If you are confirmed to have breast cancer, further tests may be needed to assess if it has spread. For example, blood tests, an ultrasound scan of the liver, chest X-ray, a bone scan or other types of scan. (There are separate leaflets which describe each of these tests in more detail.) This assessment is called 'staging' of the cancer. The aim of staging is to find out:
- How large the tumour has grown.
- Whether the cancer has spread to local lymph nodes in the armpit.
- Whether the cancer has spread to other areas of the body (metastasised).
See separate leaflet called 'Cancer - Staging and Grading Cancer' for details.
Finding out the stage of the cancer, the grade of the cells and the receptor status of the cancer, helps doctors to advise on the best treatment options. It also gives a reasonable indication of outlook (prognosis).

Hi i was just wondering if ultra sound scans are good on their own at detecting breast cancer, as i had a small lump, this was tested with an ultra sound, they said i was fine but had thick tissue inside my breast. My left breast is considerbly larger than my right. On Sunday i felt really ill and was getting pains in my chest, since then i have a really awfull burning in my left breast, it is really bad if i take my bra off and feels if i move there is something moving thats causing the burning pain. Hoping i can have some advice on this.
