It probably has something to do with PMS. My breats grow and hurt when I'm PMSing, sometimes one more than the other. And it happens over night.

do some thinking and then tell us: how much more comfortable would you feel having cancer and not knowing until it was too late, versus letting a medical professional see you naked, feeling embarrassed for a couple of minutes, and then finally KNOWING what's wrong with you (so you could address the problem in time)?

are you left handed? cause thats the way breasts are if you are right handed right breast becomes bigger because muscles in that area are used more often ..left handed bigger left breast

breast cancer in the early stages doesn't hurt. But I think you should go to the doctor. YOu'll have to get used to letting people look at you naked, because any woman with sense will have a yearly gynocological exam once she's around your age.
