I am another one who has very cystic breasts. They have only done needle aspiration biopsies (which weren't too fun) and I was 21 at the time. I am now 24 and I freak out all of the time because breast cancer is fierce on my dad's side of the family.

I am at a loss for what to do. They are lumpy - I don't know when to go get checked out and when not to. Ugh. Any advice?
