Hello, I am a new mother to a 2 months old. I felt a weird band of tissue in my breast a few weeks ago and had two doctors look at it and both said it was simply fibrous tissue. Now, still not convinced, I found a pea sized lump right above my left nipple. It feels like a little ball. I am concerned that they missed this during the clinical exams and now this is caner. I do have high anxiety, as well.
