I make sure I have an ultrasound now, @Hendrix as I don't trust just having a Mammogram - even the 3D ones (dense breast tissue doesn't show up tumours on mammograms - tho the 3D are better than the Breastscreen ones) .... so try not to over think it - I call it insurance - I'd rather have both scans done than just the one.
The breast care nurse from the Port Macquarie Cancer Centre gave me my results over the phone (nothing to worry about) and I then had the report printed out by my GP. Try not to overthink it ... tho the waiting really IS the pits :(
take care & all the best xxxx
