An ultrasound and a specialist

In a couple of weeks I get to have another ultrasound of my breasts and go talk to a specialist about it. He will compare the two ultrasounds and possibly suggest a biopsy to rule out cancer. Given that I have no breast cancer history in the past couple of generations most likely the tumors are benign but I am still freaking out a bit about the whole thing. I feel like everything is kinda standing still until I find out exactly what's going on.
