Lopsided breasts

One in 20 women has one breast bigger than the other – it is just as common as having one foot bigger than the other. Sometimes the difference is very noticeable, as if one breast has hardly developed at all.

When it comes to breastfeeding, this is not a problem – the small breast usually produces milk normally – but if you feel self-conscious about it, you may consider surgery.

In the UK, it is possible to have the operation done on the National Health Service, but the waiting list is likely to be a year or two. Usually the small breast is enlarged by an implant, and sometimes the size of the larger breast is reduced as well.

one of my breasts is a DD and the other is a C. It sucked a first but i know i cant change it so therefore i just accept it. My friends and boyfriend of five years make fun of me but i just joke around to after all it makes us unique right? my boyfriend jokes and says he "gets the best of both worlds." :)

My breasts were an even size B up until age 20 or 21. I gained some weight and my left breast grew while the right did not. I was extremely embarrassed. It didn't matter what I wore-my lopsided breasts were noticable and comments were made. My mom found a place in the area that dealt with women who have had mastectomy's-fittings for bras and bathing suits. I made an appointment and learned that my problem is very common. My smaller breast was fitted for a prosthesis which I wear with a mastectomy bra. This is covered by my insurance. Although I often still see a difference (mainly when I wear tank tops or other tight fitting tops), even with the prosthesis, it's better than nothing. Don't let this issue get in the way of dating. I have been with my boyfriend for 6 years. I told him about my problem when we first started dating and he didn't care. He still tells me today how beautiful I am. My advice is to find a place in your area that fits women for a prosthesis after mastectomy surgery. They can help you, too.

i too suffered with having two completely different sized breasts. i had an a cup and a c cup. my teenage years were filled with anxiety. the biggest problem for me was the anxiety that people would notice and tease me and i would be branded as a freak. of course high school years are the worst time for something like that. i was always told how pretty i was and boys always were interested in me but inside i felt like the most disgusting woman that ever lived. but i ended up being so shy that the only men i let into my heart were men that i knew had a good heart. and i eventually fell in love and became intimate with a man (and to my shock he didn't care at all about my lopsided boobs. he still was atracted to me and best of all he still loved me! my biggest fear was not ever being able to have a boyfriend. i always was afraid the time would come to get intimate and he would see me and throw up. lol. i ended up having a few very sweet boyfriends. none of them cared about my boobs and one even seemed to get a kick out of it by giving them nicknames. now i am a mom and still not one man has gotten turned off by me! yay! i breastfed my son and gained a bit of weight during my pregnancy. my small boob was still an a cup and the big one was a d. for once in my life i had some money saved up so i decided to go for it and i had breast surgery. i LOVE my new boobs. i finally feel like a whole person. words can not describe the weight lifted off my chest (even tho some was added ;) ten years ago when i was 18 i would have loved to have sites liek this where i could relate to others. at that time i thought i was the only one on earth like that. my plastic surgery told me 1/4 of all his breast surgeries are for women with lopsided boobs. my heart goes out to all of you. good luck and please don't shy away from a relationship because of boobs. it realyl is true when people say that "if someone loves you he will not care" as far as bras go i always bought a padded bra that fit the cup size for my larger breast. i looked for one that i could cut a small slit into the inside around the top arpmit area. (some bras have loose fabric on the inside that you can pull with your fingers, others have the fabric somehow sealed onto the padding to those don't work) then i would insert a silicone bra instert. you can buy them at any department store. i squeezed it in the small hole. make the hole small so it doesn't fall out. the funny thing is no one ever found out or questioned me. my boyfriends that knew never ran and told their friends. the whole school never found out like i feared...b/c i picked nice guys. overall i think the experience has made me stronger and helped me. if you can afford it tho...the boob job is awesome. and these days its jsut as safe as getting wisdom teeth removed.

My left breast is larger and has been since I was younger. I have found ways to hide it but I want to know where can I get a bra's with two different cup sizes?

Posted by Female on 12/08/2010 at 03:02

I was born without the muscle on my right hand side. As a result my right breast hardly grew at all. When I was was nearly 19 a consultant (Mr Eastwood)in Leeds operated and swung the muscle in my back to the front to form part of my bust and inserted a small implant. He said that I would nead a further operation when I was around 38. I plucked up the courage last year to see the doctor to see about a further operation. It was a male doctor and he told me to make an appointment with a female doctor. This I did and explained that my right hand breast was less than half the size of my left breast. She didn't even examine me and said there was no longer funding for operations like that. Would I be able to have a breast implant on the NHS?

My left breast is atleast a cup size or so larger and has been since I was younger. I have found ways to hide it but I want to know where can I get a bra's with two different cup sizes?

1 in 20 may have very slightly different sized breats but i'm sure not that many people have noticeably different sized breasts. Mine seem to be 2 sizes apart and i hate it, i feel so self conscious if i wear anything that is vaguely tight. i'm hoping they will even out, but i secretly know they never will..

Hello, I am 21 years old and I am very self conscious about my body, particularly my breasts. Firstly, they are not large, and second I believe I have some asymmetry. I wear a 34 B, but my right breast does not fill the cup as easily as the left. It annoys me and I feel very uncomfortable. Why am I just noticing it now, and will it ever change? I hate the way I look. I would really like some reassurance that I am not abnormal...

Posted by G on 27/11/2009 at 02:42

I'm finding this difficult to talk to people about cause they don't seem to take me seriously. My boobs were more or less the same at one point but one is getting bigger(I think) and the other is a size smaller. I'm padding one side but it's hard to get them to look the same. I did tell my mum but she doesn't think it matters. With my other body issues I feel like a bit of a freak. I've never had a boyfriend and don't know if this a factor, I'm not all that pretty to start with. Anyone know the best solution or any solutions?

im going through that problem, my right breast is like a size DD and my left breast is a size C i think. I hate to show my body and i cant wear any cute shirts because of it. I cant even have a boyfriend because of it.

Posted by Anonymous on 29/08/2009 at 05:23

It's reassuring that there's other people suffering like me with one breast. It would be good if there was some advice available though. I'm looking for a bra and swimwear with only one side padded and I cannot find anything like this on the internet. Can anyone advise please?

Posted by j on 15/05/2009 at 08:18

every1 always comments on the size of my breasts they think they are huge and guys give me attention for it too....but one of my breats is 3 cup sizes bigger than the other..i went to the doctors and they told me you cant get the operation done on the NHS only private which i cant afford! im soo embarassed i have no confidence with guys they think its strange that i wont get naked and i cant get changed in front of my friends or wear a bikini on holiday its awful.

One of my breasts is barely a size A and has an undeveloped nipple, my other breast is quite larger at size D, however it is a perfect breast! I wear a "fake boob" that I bought online at a store for cross-dressers. No one can tell when I have clothing on, although finding bras is quite the treasure hunt; people just think I have two huge boobs when really I only have one! Ha!

i have breast a slightly different size, i can get very self conscious about it, but i padded bra usually helps, and makes it a bit less noticeable

Posted by Anonymous on 05/04/2009 at 01:59

What should you do if this is the case? Is there a special type of bra that should be woren then?? That's what I want to know.

Posted by tara on 24/03/2009 at 03:54

I have inverted nipples. Is there any treatment that would get them normal. is this normal for my age??

Posted by nkf on 22/03/2009 at 08:25

This articles states one in twenty women have one breast bigger than the other. This is incorrect. A few years ago a male relative discussed the fact that all women have one breast bigger/smaller than the other. I proclaimed "don't be silly". He insisted that he had done plenty of research (lol) on the matter, and concluded that all the women he had inspected did have one breast bigger than the other. Later, while getting ready for bed. I decided to inspect the size and shape of my own breasts and shockingly discovered that my breasts were of different size.

My left breast is very large compared to my right breast. It is so embarresing, i feel so concious when im in public and i cant bear to go bra shopping as i can tell the difference. And cant even bring myself to let my boyfriend see me fully naked as im scared he will be turned off :( I would like to get surgery but i just dont have the money, and im scared of being turned down by the NHS as im quite young. I know it says that you should wait till your 19 for your breasts to become fully developed, but somehow i dont think they will change. I havent even told my mum as im so embarresed.

my right breast hasn't grown since i started to develope and my left keeps growing what does that mean i mean what are some causes of this

Posted by J on 16/01/2009 at 03:54

My left breast is slightly larger than the right- it isnt really noticable but I hate it. It is probably a half cup difference. My ex boyfriend never commented on it. But My question is - is this a turn off for men? Should I be embarrassed? Is it worth getting breast surgury?

Posted by Christina on 01/01/2009 at 11:58

I also have a very noticable difference in the size of my breasts. It is a 4 cup size difference. Mine is due to breastfeeding. I am okay with it. What ever is best for my baby. My husband doesn't care either so :) I live with it!

Posted by Alexandra on 30/12/2008 at 01:42
