Hi @Daisy_01,
I found a lump in my lymph node under my arm not the breast. The biopsy came back as positive for breast cancer. Ended up that 5 lymph nodes were positive.
We went looking for the primary tumour as I wanted a lumpectomy if possible. . 2 x mammograms 2 x ultra sounds could not locate it. I and the medical team could never feel the primary breast tumour which was 19mm but hiding right at the back
MRI found it.
I recently went for my 12 month scans and demanded an MRI (which I had to pay for by the way) on top of the mammogram and ultrasound as I was so scared that mammogram would not detect properly. If I hadn't found the lump under my arm (which I found by accident and was hard to feel unless I was lying a specific way with my arm up) for another couple of years things might have been a whole lot different.
Don't be afraid to ask for the tests you want so that you can rest a little bit easier.
