Mammos for all of us are stressful. I'm much better 5 years after treatment, but it's still stressful. I think I don't worry so much because my mammo didn't find my BC. I found the lump myself.
They test everything now. They don't want to take any chances. Which is a good thing. I'm sure it's very upsetting. Hopefully, time passes quickly, and you can move on!
HUGS and prayers that everything is OK.
