Hi so I went to the doctor two weeks ago because I found a breast lump, it moves when pushed and I think it's been there a while. I've been told its a breast mouse. I'm so worried. My appointment is on Thursday and I am just wondering what they do? I really hope I don't have to have a biopsy. The doctor told me because of my age that they will examine and do an ultrasound. Please help someone, I'm so worried. I'm 31
