I am 37 and I found a lump in December but doctor said it was small and mobile so it was up to me, he was happy to just wait and see. It still hasn't disappeared so I was referred to the breast clinic and they saw me last Monday. I had an ultrasound and then a fine needle biopsy. Today I went back and they said that the ultrasound showed results "consistent with a fibroadenoma (U2)" but that not sufficient cells were taken by the biopsy. She then did a core needle biopsy. I am trying not to worry but I still am. If it is a benign fibroadenoma, why are they still doing more tests?
