The right side and the left side of the body are not the same size. Usually you have one that is bigger and you notice it buying shoes for instance when one shoe is slightly bigger then the other. A breast can also hang lower then the other so it seem larger.
All humans have one side of the body that is bigger then the other. This can also show on breasts and all women usually have one bigger then the other or one that starts lower down the the other.
Not necessarily. It is common for one breast to be slightly larger than the other. If in doubt, take a pregnancy test, bought from a chemist.
Yes this very well can happen to some girls, as they may not have worn the correct size bra for a long time, so now one breast is slightly larger then the other one. It is very common for one to be slightly bigger than the other.
Please note you feel one breast is larger, there may not be much diferrence actually. Breasts are not exact in size.
Yes it can be, but many women suffer from 1 breast bigger than the other.
well some times its weird because they say that at lest each part of your body is bigger then a other like look at your arms 1 is longer then a other its weird hue.
A flap breast reconstruction surgery is actually when you use tissue, skin, fat and muscles from other parts of the body to build the breast out to make your breast bigger.
If you are in puberty, one breast may grow faster than the other. The smaller one catches up. However, almost all women have one breast slightly larger than the other one.
No product or action (other than surgery) will make your breasts grow bigger. Time is the only thing that has an effect.
Because when you are born you have one breast bigger than the other it is natural so dont worry about it.
There is no 'normal' weight. Breast come in many different sizes. Often one breast may be slightly larger than the other breast. Also, as a woman ages, so the fat layer in the breasts will slowly reduce.
