Why are some women flat-chested?






Stop the
Education and opinions about the way we are bombarded with images of beauty and sex by today's media, as well as other sources. TV, movies, magazines, commercials, and a score of other avenues give us an unhealthy picture of "beauty".




















The material on this page can largely be found on other parts of this website too, amidst various visitor questions and answers, but it is gathered here for easy reference.

What does it mean being flat-chested?

Sometimes a woman's breasts don't develop much during puberty but she remains "flat-chested" - without any palpable breast tissue. Typically, flat-chested girls do have a nipple that looks swollen or elevated, but for some reason the breasts don't grow in size at all. Flat-chested girls do get pubic hair and start menstruating just normally - it's just the breasts that don't develop like most girls.

Unfortunately experts like doctors and lactation consultants don't really know WHY this takes place. However, during pregnancy the breasts do usually develop more and grow in size, and flat-chested women can breastfeed and produce milk. A totally flat woman's breasts can grow to a A or even B cup during pregnancy and while breastfeeding. However, obviously with small 'storage space' the baby might need to nurse quite often.

Am I abnormal or deformed?

A flat chested woman is not abnormal in the sense that her breasts are functional and can make milk. She's also not abnormal in the sense that there are many many other women out there with a flat chest (or almost that). They typically used padded bras so you don't necessarily notice it from outside unless you know the person. It is true that a flat-chested woman's breasts did not develop as most women's, but like already noted, it is not known why this is.

Are you truly flat-chested?

We receive seemingly an endless stream of comments from "flat-chested" teenagers who are very worried about their breast growth. For example

I am 13 years old. i just got my period but i am very flat chested. i dont even fit into A cups will my breasts still grow even tho ive already gotten my period?
i am barely a 32A an im so depressed. every girl at my school has breasts and i must be like the smallest. i really want them to grow but how?? how?? i dont want surgery. does exercise help? can u give me any advice.

I have a question. I am 15 and have had my period for about 13 months, and my breasts are not growing at all. Why are they not growing. They don't even fit in an alomst A cup. My breasts also look like hypoplastic tubular breasts.
Hello, I really appreciate this website, and the q&a page with other girls' questions really helps, but I have a problem and need advice. I am 15 and I had my period when I was 13, and I have pubic hair and all the other signs of puberty, but I don't even fit an A cup yet. I am normal weight, but almost completely flat-chested. Please give me advice, because I think by now I should be developing more, like the other girls my age, and I'm afraid I'm abnormal.
I'm 16 years old and just got my period. I have NO breasts, whatsoever. I barely fit into a 32 A. All the guys in my school call me "flat" and every girl in my school, including the freshmen have bigger breasts. Will I ever grow any more? I don't want to be this size for the rest of my life! I'm afraid to go to pool parties and have a serious boyfriend because I don't want him to see that I have no breasts. Please help!

First of all, many of these girls mention being almost an A cup or so - which is not flat-chested. It may be small breasts, but not truly flat-chested. Secondly, if you're a teenager - and especially if you haven't yet gotten your periods or just recently got them - your breasts are probably still developing and growing, and it's too early to know if you're going to be a true flat-chest.

Another reason why teenagers sometimes have up size A or AA is if they're dieting a lot or even anorexic. So make sure you eat well and healthy; women who are underweight usually have very small breasts. A fatless skinny body means no fat in the breasts either.

i am almost 18 years old and i got my period when i was 16. i was flat chested before my period and i still am. now when i say flat i mean absolutely flat. no bump at all. are you truly telling me that that is how i will always be? i should get some breast shouldn't i? i don't even look like a girl. please give me some hope!! could i have a disease or something?

Hello, my name is stephanie and i am 16 years old and i have no chest at all. I am a 32A. Actually I dont even fit into a A cup. I only weight 95 pounds, but i eat like a big. I hate it so much. I cry every night, because i cant be like any of the other girls. I go to school with a pretend bra that makes people think i have a chest. I hate it because i cant show of my good shape with a tight shirt, i could only wear big t-shirts and i am getting sick of it. I dont go out with any guys cause i dont want them to find out that i am wearing this bra. I dont go whopping with my friends, and I NEVER go shopping for a bathing suit. I just dont want them to find out that i have this bra on. If people find out about this they might tell the whole school and i will be sooo embaressed. I need help I haven't got my period yet and i am so sick of not being normal. Can you help me?

USUALLY, flat chested girls' nipple grows bigger or looks 'swollen'. If that is not the case, and f you got your period fairly late... or especially if the period has not yet started at 16, there is a possibility of some hormonal disorder or delayed puberty for some reason. It is advisable to see a doctor. See also Delayed puberty at KidsHealth.Org and Delayed Puberty at

What if I'm TRULY flat chested - can I get bigger breasts?

Flat-chested girls often wonder how to increase breast size; which is very understandable in this society where the pressure to have big breasts is so great. If you get pregnant, that will quite probably make your breasts grow, BUT as noted elsewhere on this site, there does NOT exist any food or exercise that would increase your breast size. The herbal pills so much marketed may sometimes, for some women, slightly increase the breast size, but they don't make any difference for most and the change is not permanent.

Breast implants will of course make your breasts bigger. Unfortunately, breast implants bring with them a lot of physical suffering and sometimes even a crippling disease. You will need several surgeries during your lifetime. Breast implants also will endanger your future ability to breastfeed. But of course if you're an adult, the decision is yours.

How do flat-chested women feel?

Because of the great emphasis that fashion magazines place on big breasts, flat-chested women easily feel embarrassed, that men won't like them, or that they are 'deformed' or outcasts etc. Please read few comments sent to this website and the answers.
hi,i'm 15 years old and i'm flat chested and i had my period when i was 11. My mom said not to worry but i do! I already have my public hair growing but not my breasts.i still wear training bras not real ones. My nipples are pointy but the rest of my breasts are not big. People, Guys make fun of me! I need help! My mom had her breasts when she was 14 but what's happening to me?
I've been writing at several places in HUGE FRUSTRATION. My cup size is negative 2 inches (I'm 24). I am made fun of all the time even though I'm so old. I thought people only made fun in high school but since I look so young, like I'm 12, they won't stop with the comments. I'm so confused about how ugly I look that sometimes I feel like I need to start acting like a man to fit my image although inside I'm as girly as you could want. My question is: what are you supposed to buy in terms of bra when your cup size is negative 2 inches?? The bra industry makes NOTHING for people like me. I feel so left out of the game. All my female friends my age can wear bras and are beautiful. I'm ugly and guys HATE the way I look. But... so what do I wear?? I've been wearing an AA and it's too big for me and keeps riding up. It's not fun. How many girls % wise would you say look like me? Why are guys grossed out by my flatness? Why am I made this way? Is it bodyweight? I weigh ~120. I'm 5'6''. I hate myself.
I really like your articles on who needs breast implants but I'm sorry to say I still don't feel so good. I'm 32 going on 33 I have a flatchest like in grade school. I have severe depression just walking outside to get in my cadillac because there's always a prettier woman or girl passing me by and I have to face it men like boobs to look at. Is there anything that will make me feel better with surgery because I'm looking forward to going to work in nursing home soon. thanks so much for your time, tig

Having a small chest can be embarrassing in this land where big breasts are adored and emphasized to such an extreme... Actually, flat-chested women ARE to produce milk... so they're NOT lacking in that sense. They ARE women.

Guys or men will NOT necessarily be "grossed out" by this... maybe some would, but not all. How the man acts will also depend on YOUR attitude towards your body. If you hate your body, people around you may sense it, and that may then influence their attitude toward you. On the other hand, if you can accept your body and are happy, and take the best care of it you can, that will also affect how others see you.

You may think that men always are drawn to breasts and want to "play" with breasts. But sexuality is NOT dependent on breasts. It is based on love, and that someone loves you, he's not bothered by lack of breast tissue.

Men are drawn to whatever they are culturally taught to be drawn to. Men in the US probably want to play with breasts because they THINK they are supposed to do so... not because it is some kind of automated response. Customs are different in different parts of the world. In a loving relationship between husband and wife, they can tell each other what they might like and enjoy, and not just "grab breasts" or some other part... It's a mutual love situation, not some kind of scripted play that has to go according to some pre-written form.

And not all men are so totally obsessed about breasts. Read some of the visitor comments on Breast obsession and Breast gallery pages. Especially look for the occasional comments from males.

And, prettiness is not based on breasts alone... in fact that would be just a small part of it. Maybe you're always observing other women's chests - well quit. Look at their face or hair or legs too, or general apperance. Quit reading women's magazines with 'belief' - the models you see in there are not the norm, nor would they look like that without extensive help from makeup, camera tricks, and plastic surgery.

The lack of breast tissue does not make you an ugly woman! Most of us have some kind of imperfection in our body, yet most women look pretty in their own way - it is quite rare to find a totally homely looking person. And, one of the biggest things in being attractive is a POSITIVE attitude and an open and helping attitude towards our fellow men... people like to be around such people, no matter what size breasts or legs or buttocks.

It all boils down to the fact that the PERSON should be much more important than ANY body part. If people abide by this, then even flat-chested girls wouldn't feel so embarrassed. At any rate, people who care really about you, realize this and they care about you no matter what your breast size.
