First I want you to know, you are not alone! i had my mamogram March 31 as I do every year. The did discover a mass so I had a second Mamogram and ultrasound. In my case I do have Invasive ductal carcinoma, however many times it is just a scare. But I understand the stress of waiting. I think not knowing for sure bothered me more than knowing. I'm Ok now. I know I'll be Ok. Try to keep a positive attitude. I found Knowledge helped so I looked up everything I could. Just remember to breath! You'll be OK
