Got the scares today

Went in for my exam. BS ordered on the spot a mammo, and when I was done, the tech went to my doc, who came to see me, and told me that I needed and ultra sound on my breast.

I think I almost peed in my pants. What..........???

Finally all good, clean, it was just that they do at the hospital once a year and ultra sound with the mammo.

My doc ordered also ultra sound to check abdominal, and bone scans. I have NO symptoms and feel great, so I dont understand why this hospital ( Mc Gill University)  is doing annual scans. I read they usually dont do that, unless you show symptoms.
