My 8 year old dd came to me late last night and said she had a lump by her left nipple. It is hard and slightly bigger than a marble. You can’t see it but you can very definitely feel it under the skin. Nothing on the other side. I immediately panicked and of course being a Friday night I have to stress over it all weekend until the dr’s open Monday morning. I’ve been looking on google and wonder if it could be a ‘breast bud’ does anyone know what they feel like? How hard are they? I would really appreciate any advice very anxious mumma here.
