I woke up Friday night with my left breast in PAIN. I started poking around and found a lump. Saturday it was still painful, but better, Sunday again painful but better and Monday the same. I called and got into the gyn today. She felt it and said, wow, that is big. Then she asks if I had my mammo last year (which i did in June) and then she says something about my dense breasts. At that point I ask her if I should panic. She said, no, I think you have a cyst, but we need to schedule you for a diagnostic mammo and ultrasound, which I will be going to tomorrow.

My question is (assuming it is a cyst) what about this pain? It's better than Friday, but it's still pretty painful. My cycle is due to start this weekend. Will that help? Will I need to get off of birth control pills? I'll be talking to my doc, but I was checking to see what kind of experiences others have had.
