Hi. I'm 48 Years Old And Am Diligent About Annual

Hi. I'm 48 years old and am diligent about annual mammograms and exams. Last week, I got the dreaded callback stating "architectural distortion"on the left breast. That's the extent of what my physician will communicate to me. I demanded copies of prior mammograms and I see they state "density may be hiding small masses". What the heck, why didn't they call me back if they couldn't everything for years! I was never told. Should I be terrified now? I've googled that architectural distortion can accompany cancer. The mammo says no visible mass or calcifications. Of course, they called me on Friday and I am a wreck.
