I am 35 years old with no family history of breast cancer. I noticed a raised area on my breast upon looking in the mirror about 6 moths ago. Upon a self-breast exam I felt a hard lump on my right breast. Since I don't have breast cancer in my family I have just been keeping my eye on it. The lump is hard, and does not change in size with my menstral cycles and is painless. 3 weeks ago, I noticed yellow discharge from my nipple on my right breast. I finally went into the doctor and a mammogram was ordered. I did not hear mammogram results and the radiologist (MD) did an immediate US on me and said that she could see a solid mass in my right breast and that it needed to be biopsied. She then did a core biopsy and now I am playing the waiting game. My question is, is this just routine or is there something suspicious about these procedings. I have not received any clarifying information and I am a little worried.
