HI, I had a mammogram last month as I had a lump in my left breast. My biopsy results came back clear - i was advised that it was a fibroadenoma - and I breathed a sigh of relief. I have just noticed a lump in my right breast. The mammogram of my right breast was all clear last month but I am sure I now have a lump. Has this happened to anyone else? I know I should go to my GP but I don't want to waste their time as everything was ok last month.
