I was diagnosed at 65 (as are many others) & mine were still very dense at that point in time, so that knocks that theory on the head for me, I reckon! ;)
I'd never had kids, so not breast fed (and don't know if that makes a difference at all, as I didn't have all those 'hormone surges' associated with pregnancy etc ....)
Being on AIs long term apparently will make them a lot less dense (as my US lady explained), as she had my pic up on her computer & it looked a lot less dense than I'd imagined it to be!
I wonder if going OFF the AIs will 'keep them' less dense or if they will resume the former density? Only time will tell, I guess.
I'd been told from my late 20s (with my first lump scare) that I had 'lumpy breasts' - I now believe that that term also means 'dense breast tissue'.
