Lymph nodes

Hi, I had a mastectomy two weeks ago and have just had the follow up call which I was dreading.The consultant said although it was big, 12cm, they got it all. 14 lymph nodes were taken but they couldn't find anything then so they are doing further tests to make sure? He said if they did find anything it would be very mild. I will be having chemo and radiotherapy. Does this sound familiar to anyone else who had lobular breast cancer?

Thank you.
