Thanks for posting with your query about PET scans.
Having multiple investigations can be a worrying and stressful time.
Positron emission tomography (PET), is a scan that produces a 3D image to show the structure and function of organs or tissue being looked at.
It is not possible to comment on individual cases and it is unclear from your post about your situation. A PET scan may be requested for a number of reasons. It may be requested when other tests such as CT or MRI scans have not provided enough information for your specialist team to assess your breast cancer and plan your treatment. A whole body PET scan may be requested to look at other areas in your body, whereas a CT and MRI are often only looking at specific areas such as the breast.
You may find it helpful to talk through with your specialist team the reasons why they have requested this test.
Do call our free, confidential Helpline if you would like to talk this through or have any further questions. The number is 0808 800 6000.
Our opening hours are Monday to Friday 9am - 4pm and 9am -1pm on Saturday. Out of hours you can leave a message and we will call you back when we next open.

I think this is something you need to ask your oncology team - you can contact the oncology nurse by phone any time. They are both expensive tests so they will have clear reasons if they’ve recommended both. I had both but several months apart.
If either scan is a cause of disproportionate anxiety, tell your oncology team and they will be able to help you with this (or your GP - though mine washed her hands of me once I was under the hospital’s care!).
Hope you get reassurance,
