If your oncologist told you that the tumour has shrunk, this usually means chemotherapy is working.
It’s difficult to say what they may have meant by not being able to feel the margins. Sometimes, different areas of the tumour can respond more or less than other parts. It may be the margins/edges of the tumour have shrunk right down and so can’t be felt on examination.
You may want to contact your breast care nurse who will be able to explain what your oncologist meant.
However, usually being scheduled for your next chemotherapy cycle is a sign your breast team are happy the treatment is working for you.
