Hi, few days ago on the first period day I found a small lump which at the time was very hard and round. Phoned my dr who sent me for an u/s. Indeed the radiologist found a 8,6*4,6 growth smooth and round. The conclusion was Birad4a and I am going to a breast specialist today . The radiologist said I have to get a biopsy. Its close to the surface at 9 o'clock position. Anyone with birads 4a had a favourable outcome?
