A Woman’s Breasts Are Usually Not the Same Size

More than 90% of women have breasts that are different from each other in size, shape, or position on their chest. It’s usually the left breast that’s larger. In almost 25% of women, the larger breast is at least one cup size bigger than the other. This can make bra shopping an even bigger challenge than usual.

Over the course of a woman’s lifetime, her breast size will change up to six or seven times.

Also, a woman’s hormones influence almost every aspect of her breasts. This is why it’s perfectly normal for women’s breasts to change in consistency and sensitivity from week to week during each menstrual cycle.
