Your pathology results

Your pathology results give details about your breast cancer that can help decide the treatment you’re offered. Read our guide to pathology results below.

1. What are pathology results?

If you've had a to diagnose breast cancer or you have had breast cancer surgery, the tissue removed will be looked at under a microscope by a doctor called a pathologist. 

Tests may also be done on the tissue to get more information. 

The results give details about the breast cancer that helps determine the treatment you’re offered. 

Waiting for biopsy results?

If you’re waiting for the results of a biopsy, you may find it useful to read our information and tips about waiting for your biopsy results.

2. How long do pathology results take?

Results usually take between 1 and 2 weeks. 

Some tests take longer than others and may be done in a different hospital to the one where you’re being treated. 

Occasionally pathologists get a second opinion about the results which can also delay them. 

Your specialist or breast care nurse should be able to tell you when your results will be ready. 

Most people feel anxious waiting for their results. How long you wait depends on the type of biopsy or surgery you had and where you’re being treated. 

Getting your results

When you first get your results, you may find it hard to take everything in. 

It can help to bring a relative or close friend with you to the appointment. 

If you’re told anything you don’t understand, ask your specialist or breast care nurse to explain. 

You can also call our helpline - top and bottom of this page - to help you understand the results. 

3. Pathology reports

Each time you have tissue removed, it’s looked at under a microscope and a report is written by a pathologist.

You can ask for a copy of your pathology report to read through with a member of your breast care team or later in your own time.

The amount of detail in each report will depend on what tissue was removed and how much.

Not all reports include the same amount of information. For example, a report after a biopsy will not contain all the information that’s in a report after surgery.

You may need to wait for all your reports to come back before a full treatment plan can be decided.

4. What does a pathology report look like?

Not all pathology reports look the same. The layout and terms used vary between hospitals. However, most follow this structure. 

General information 

This will include your name, date of birth and hospital number, your specialist’s name and the date of your surgery or biopsy.

All the information in pathology results is considered together when deciding which treatments to offer you and their likely benefits. 

No one piece of information should be looked at on its own – it always needs to be related to all your other results.
