From a simple CT scan (not PET) is it easily possble to distinguish between:
1) a scar left after successful non-surgical treatment
2) a cancer remaining after unsuccessful treatment?
Thanks for getting in touch with us and thank you for your question.
Unfortunately, it is not possible for a CT scan to differentiate between scar tissue and a cancerous tumour. For this reason, a PET scan may also be required to assess whether there is any cancer remaining.
However, if there have been clear margins taken by the surgeon, a PET scan may not be required if the team is satisfied that the cancer was fully removed.
I hope this answers your question, but please don’t hesitate to get back in touch if you need any further information or support.
