Mammogram didn't show the cancer

I know how you feel. I had an all clear last October it was my fifth yearly mammogram after BC was found on a mammogram . In June I found a pretty big lum identified as BC from a mammogram . I went to for numerous scans and they found a cancer in the lymph gland left over from the last time. This wasn’t picked up by surgeon or mammograms because it’s up high almost under my collarbone.  I will be having a bilateral mastectomy after chemo this time. However if I hadn’t found this lump because of my age I wouldn’t have had any more mammograms anyway. Dread to think how far it could have spread from that lymph node. 
I know it’s reliable but maybe they need to put in some research into doing alternative testing. 

You are entitled to a second opinion so maybe that’s what you can apply in this case. 
Good luck with your quest. 

I'm really sorry to hear what you are going through.  At least they have found it now and are dealing with it.  I had a lumpectomy with a Licap flap partial reconstruction so my breast feels a liitle lumpy anyway and I could easily miss a worrying lump.  I think I will ring my BC nurse and ask her if I can have an ultrasound after my mammogram to stop me worrying. I hope your op goes well and you can move on.
