Long-Term Mammography Needed for Breast Cancer Survivors

Yes, I am excited about being an almost 5 year survivor only to find out that now it is 10 yrs that now seems like the goal to aim for!

I wish someone would explain to me how they do a mammogram of no breast?  Is a mammograpy diff from mammogram, maybe I'm missing something here.  Looks like an ordinary scan would not only show what's in the flat chest there, but also would notice anything else in the vicinity that looked off.  I be stoopid, just saw this come up in the general forums, and don't want to bypass an easy detecting test if it's necessary.
