Hi, I am not sure I am posting this in the correct place, but my mum was diagnosed with triple negative breast cancer in July. Her tumour was 5cm and 2 positive lymph nodes under arm.   She had 9 x weekly PC chemo and has had 2 x EC chemo, with the last one in due this week. She had an mri scan after the 7th weekly PC chemo and today she received the results.   Sadly, the scan only showed a 5mm shrinkage of the tumour. There was talk of the volume within the tumour reducing , but not too sure what this would indicate.   It could have been worse news, but we are very disappointed as we were hoping for more shrinkage after 7 weeks of chemo, especially as I had heard that triple negative cancer responds well to chemo. What concerns me is, if the tumour has not responded well to the chemo, would that mean that any cells that may have broken away, not have responded either? Anyone experienced anything similar?
