I am 22 years old. I have had a lump in my right breast for a year now. I had an ultrasound and it was okay. They said just monitor it. This year it apparently has doubled in size. They want to biopsy it. That just makes me nervous. I do have anxiety disorder so the unknown is freaking me out. The doctor said he is not really worried. Just a precaution which I am glad for that. Still nerve wracking...has anyone else had this?
