It could just be premenstral, I have them on mine too around the time of my period, I always thougth I was prego, but it was just my period.

I actually find blue veins on breasts very very sexy.... :wink:

Um... I developed those after my breasts stopped growing. They aren't so bad once you get use to them.

Aloha ladies,
I am extremely frightened at this moment. I looked at myself in the mirror and I saw BRIGHT BLUE VEINS on both of my breasts! I have never seen this before. I am NOT pregnant, nor could I even possibly be. I had a full hysterectomy about 3 years ago! Please reply if you have experienced this or similar. I am totally freaking out!I keep reading that women who have had these blue veins are pregnant or think they are. Since that is DEFINITELY NOT my situation, what is it then??? Has anyone else had this happen to them? Please talk to me... I am a 45 year old woman, unmarried and I have NO children. Basically I am alone. I would appreciate any help anyone can offer to me.

This is very common. I developed them when I was in my late teens and still have them. They are not a concern. It can be from a hormonal trigger like menstruation or perimenopause. Your gyn should be able to ease your concerns if you discuss this with her/him.
