It is very unusual for both sides of the human body to be entirely symmetrical. This is also true for breasts,with most women having one breast larger than other. In most women this is not noticeable either in or out of a bra under normal scrutiny. However, for those in whom it is noticeable, or are very themselves very self-conscious about the difference, it can play as a major factor with their self-confidence, sociability and enjoyment in life.  

In most parts of the UK, it used to be the case that if your breasts were more than two cup-sizes different from each other you could be considered for breast surgery on the NHS if you fulfilled a number of criteria.However, with tightening NHS budgets this is now very uncommon, but in cases of marked asymmetry if may be worth having a discussion with your GP.Correction of breast asymmetry is individually tailored to each patient depending on which breast she prefers the size of, whether she is happy to have both breasts being operated on (with either a breast augmentation, breast reduction, a breast lift or a combination of these), and whether she would like to change the size of both breasts. The aim of this surgery is to improve breast asymmetry, however rarely (if ever) are the breasts exactly symmetrical at the end of surgery. It is important to understand this prior to surgery as otherwise you will always remain disappointed with the outcome.
