It is usually recommended that patients should be 18 years old before undergoing cosmetic breast surgery. The argument is that the breasts may still be developing and, if surgery is too early, this development may continue requiring more surgery later. It is also felt that psychologically development is also incomplete.
However, there are good reasons why early surgery might be sensible. The breasts may be deformed, unequal in size and or very large, all causing psychological harm, which could be averted by surgery. The common deformity is tubular or conical breasts. On these occasions, the surgeon is likely to ask for confirmation from the parent, GP, and psychologist.
