when first had ultrasound and biopsy the tumour was said to be 35mm. later when had surgery I was told it was 26mm, my doctor was told it was 25mm. so did it shrink? or is it so hard to size…
I was told they are measured in a slightly different way on mammogram and ultrasound when I queried mine, was told 25mm on one, 17mm on the other but after surgery it was actually 16mm
After surgery it will be measured properly as they have the tumour rather than measurements on imaging x
Thank you for your post.
It is understandable that you are concerned about the different measurements given about the size of your lump between your biopsy and surgery. It can be worrying when the information given about a diagnosis differs between what you have been told and what’s been passed on to others.
Different techniques of imaging are used in order to be as accurate as possible in assessing the size of an area of change or lump within the breast before planning treatment.
While scans can give a good idea of the size and shape of a tumour, they are never as accurate as looking at the tissue under the microscope. As @chillout365 and @NatalieS42 says, scans such as mammogram and ultrasound measure the lump in different ways and it is not uncommon for the size to be different on the final pathology report after surgery.
