Scared and worried

Hello all, I went to have a breast ultrasound last Monday. The results were supposed to head over to my doctor, but I haven’t heard from them. I called today to schedule an appointment with the doctor. I received that appointment for next week. I was feeling ok since I haven’t heard from the doctor. I was thinking if something was wrong I would’ve been contacted. My sister who’s a medical assistant told me if nothing was wrong they could say so over the phone. This has sky rocketed my anxiety. I went to the doctor for two dents that appeared on my breast. I was sent in for an ultrasound. Now my breast has enlarged pretty fast. I’m so scared I have something wrong with me. When I google breast enlargement/ indent it keeps bringing me back to inflammatory breast cancer. I’m so scared. I don’t feel like my doctor is serious enough. I feel like if something is wrong she should have called. So I just wanna know do I have to get referred for a skin punch biopsy? Or can I just request one? If anyone knows your input is greatly appreciated..
