Repeat imaging after treatment: what is routine and what is not

For most women who have finished treatment for early breast cancer, the answer is a yearly mammogram and a clinical examination. That is it. Routine whole-body scans, PET-CTs and tumour marker blood tests are not part of standard follow-up, and that surprises almost everyone.

Why so little

It is not about cost. Scanning people who have no symptoms has been studied carefully, and finding a recurrence a few months earlier through routine scanning has not been shown to help people live longer. What it reliably does produce is false alarms, extra biopsies and a great deal of fear.

What replaces the scans

You do. Follow-up rests on you reporting new symptoms that persist, and on a yearly mammogram of the remaining breast tissue. Being told what to watch for is more useful than a scan you have once a year and worry about for three months beforehand.

Being told you need fewer scans feels like being abandoned. You have spent months inside a system that watched you closely, and it stops almost overnight. That reaction is normal and it is worth naming rather than pushing down.

What a scan would not give you

The reassurance from a normal scan lasts weeks, not a year. Many women describe the months before a routine scan as worse than the months without one. Scans also find harmless things surprisingly often, and each one then needs following up.

If you want a scan anyway

Say so, and ask your oncologist to talk it through rather than simply refusing. There are situations where the answer is yes. Going outside your team to arrange one privately is the version that causes problems, because the result arrives with nobody who knows your history to interpret it.

What this page cannot tell you

It cannot tell you your own schedule. That depends on your stage, your subtype, your surgery, the treatment you are on and any inherited risk. Ask for your follow-up plan in writing, including who to ring and how quickly you can be seen.

Keep one folder, and take it everywhere

Keep your surgery notes, your pathology report, your discharge summary and every mammogram report together in one place. When you move city, change hospital or see someone new, that folder is what lets them pick up where your last team left off without repeating tests you have already had.
