IT’S NORMAL TO HAVE DIFFERENT-SIZED BREAST
Having breasts or other body parts – like feet or hands – that are different sizes is perfectly normal and common.
Teens may notice that one breast grows ealier or faster than the other. Often this size difference will even out by age 20. But it’s normal for an adult to have breasts that are different sizes too. About one in four women have breast that’s larger than the other..
The reason for this difference in size is usually an unequal amount of fat tissue on both sides, which has nothing to do with milk-production part of the breast.
