Many women are self-conscious about their breasts. They feel that they are too big or too small or too saggy or too full. Many women also wonder about the symmetry of their breasts. Most women notice at least some size difference between their breasts, and for some this difference is noticeable. Many times this is normal, but in some cases, a larger breast can be a sign of a problem.
Natural breasts are almost never symmetrical. One is almost always bigger than the other. A large difference such as a B-cup and a DD-cup can be remedied with surgery or by wearing padding on the smaller side.
During breastfeeding, it is normal for one breast to seem fuller or larger than the other. If baby favors one side, it will fill up more than the other. After weaning, breasts should return to similar sizes.
After breast-implant surgery, it is normal for one breast to swell more than the other. If after four months, there is still a noticeable size difference, see your plastic surgeon to find out what is wrong.
A sudden change in the size and shape of one or both breasts can indicate breast cancer. See a doctor immediately if either breast suddenly seems larger than normal.
Breast implants can break down, leak or rupture. If you have implants and one breast suddenly seems smaller than the other, see your plastic surgeon immediately to find out what has happened.
