Like Kayvie, I found my lump and there was nothing obvious on the outside in spite of it being approx 2 cm. however, mine was between mammograms. I had had mammograms and ultrasounds religiously every two years for ten years and was not due for another until May this year, I found the lump 6 months before it was due. Thank goodness I self examined, but I wish I had done it more regularly and thoroughly, then I might have picked it up sooner.
Now I tell people that I talk to that they must know their own breasts inside out and not to just rely on the mammograms every two years. And if they find something different get it checked out.
one friend has just gone for a mammogram and is anxiously waiting the result. I hope she is clear.
