I've never really paid much attention to my breasts, to be honest, but a few months ago I noticed that one seemed significantly bigger than the other. It is possible that it always has been, but I just didn't notice - yes, I really am that thick - but it took me by surprise and I kind of think that if it had always been like that I would have noticed before (I'm hardly a teenager!!). It also feels heavier than the other. There's no other signs and no lumps that I can feel. It can get a bit painful at times and tender, but everyone's does. I'm normally quite relaxed about my health and normally wouldn't dream of going to the Dr about this, but recently I heard about a friend of a friend who didn't have obvious symptoms of breast cancer being diagnosed with it. I'm just a bit confused.
