If you wear a bra when you sleep will you get breast cancer or something?

I know this question sounds really childish, but is it true? I've heard many things. x_x

-If you wear a bra while you sleep your breasts won't sag as much.

-If you wear a bra while you sleep your breasts WILL sag more.

-You can get breast cancer if you wear a bra when you sleep because it deforms your breasts or something like that.

Any thruthful answers out there? Please. :)

    Some of these statements are BS, like the first one, but others may have some truth in them.

    Let me explain: first off, bra's do not prevent breasts from sagging, rather the contrary. So it is a myth that bra's prevent sagging of the breasts. It is rather age, gravity, genes and the amount of children that you have that will determine how saggy breasts become.

    About breast cancer and bras: it is not proven that wearing a bra 24 hrs will cause breast cancer, however studies have proven that there is a link:

    One study, done by Singer and Grismaijer, suggested that women who wear bras 24 hours a day may have more than a 100-fold greater incidence of breast cancer, compared to those who don't wear bras. They wrote a book called Dressed to Kill to explain their theories to the lay public.

    Some researchers feel that the connection is that bras cause breast congestion and slow down lymphatic drainage of the breasts. Toxins that we eat, drink, inhale and absorb through our skin tend to collect in our fat cells. Our breasts are made of breast tissue and fat. So any constricting garment that slows down lymphatic drainage increases the amount of time that these toxins can damage our breast cells.

    Here some more explanation of how bras are more likely to cause sagging of the breasts than preventing it:

    What causes sagging of breasts?

    Sagging or drooping of breasts is a natural, inevitable process that happens to all women at some point - except those with fairly small breasts. The most notable sagging happens with the process called breast involution (see below), but breasts can start drooping a little at any age, because they do NOT have muscles in them. They have ligaments and connective tissue. When the gravity pulls the breasts down, those ligaments and the skin can stretch, and so the breast then droops. This depends on the elasticity of your skin and of your ligaments, as determined by your genes and diet, and also on normal aging processes. Obviously large breasts will sag easier since the gravity is pulling them down more.

    Breast involution is a process where the milk-making system inside the breast shrinks because it's not needed anymore. This happens either after weaning, or right after pregnancy if you don't breastfeed at all, or during menopause. When the tissues inside breast shrink, and the skin surrounding it doesn't, the breast can look 'empty' and saggy. Over time, some fat gets deposited back to the breast so it will look somewhat fuller but sagging usually remains.

    Will bras keep the breasts from sagging?

    Bras will keep your breasts from sagging while you're wearing them - but not for the remainder of time. There is no published medical literature showing that bras prevent sagging. Even the bra industry seems to know this, as the following quote illustrates:

    "We have no evidence that wearing a bra could prevent sagging, because the breast itself is not muscle, so keeping it toned up is an impossibility. What it can do, particularly for larger-breasted women, is obviously to provide the comfort and the support. So, if a woman wants a particular breast profile, she will buy a particular brand, and that is what they're designed for. There's no permanent effect on the breast from wearing a particular bra. The bra will give you the shape the bra's been designed to give while you're wearing it. Of course, when you take it off, you go 'au natural.' "

    executive John Dixey at Bras, Bare Facts documentary

    However, there is some support for the idea that breasts in bras actually sag more (when bra is taken off). How could that be since the main idea of bras is to lift the breasts upward? The main idea is that the ligaments which support breasts in normal circumstances, would atrophy (get thinner and weaker) when breasts are immobilized within bras and don't have to bear their own weight.

    There are lots of studies showing that ligaments and tendons in limbs do atrophy when the limb is immobilized. Bras obviously prevent the the natural slight up-down movement of breasts when we walk, and let shoulders bear the weight of breasts. If breast ligaments behave like limb ligaments, it may be a matter of "use it or lose it".

    The only study ever published on the subject of bras and sagging was done in 1991, in Japan. The study suggests that a bra can actually increase breast sagging rather than the opposite. The abstract says (emphasis mine):

    "Eleven adult female subjects aged 22-39 years wore a certain brassiere for 3 months while anthropometry and moire fringe photographs on the anterior trunk were taken regularly once a week. After the 3 months, the brassiere was not worn for another 3 months. Then the measurements and photogrammetry were repeated for comparison using superimposed moire configurations. The results are summarized as follows. Regardless of slim or obese trunk, subjects with pendent breasts showed the highest degree of breast form "correction" from wearing the brassiere. In all subjects, after 3 months of brassiere constraint, the underbust circumference was smaller but the chest circumference became enlarged, the distance between the right and left nipples became wider, and the breasts tended to hang down. This change was more marked in obese subjects with pendent breasts. And when this type of subject wore a "well-fitted" brassiere for a long time, her breast form became developed, that is, her breasts hung down more."

    French study the necessity of wearing bras even further

    Another study with similar results was conducted in 2003 by Laetitia Pierrot and Jean-Denis Rouillon. In it, 250 women who practiced sports stopped wearing a bra for one year. They were followed regularly with questionnaires and biometric measurements. At the 6-week checkup, the ladies experienced some discomfort from abandoning the bra, but this disappeared later, and by the end of the year 88% of the women reported improved comfort compared to before the study.

    The measurements showed firmer, more elevated and perkier breasts. For example, the distance from the nipple to the shoulder bone was reduced, which means the breasts sagged less. They noted a better muscular development in the rotator muscles of the shoulders and the pectoralis major. Also, stretch marks on breasts became less visible.

    [The development of the breasts after discontinuing wearing bras. Preliminary longitudinal study of 33 volunteer sportswomen. Thesis presented December 19th, 2003, Faculty of Medicine and Pharmacy, Besancon, France.]

    Here is an article discussing that study (in French): Le soutien-gorge en question. See here for an English translation. There is also a more recent study by Jean-Denis Rouillon: Santé Le port du soutien-gorge déconseillé par un médecin bisontin (Besançon doctor advises against wearing bras ).

    Conclusion

    The rules of the society may force you to wear a bra to work or to social occasions, but there's no need to wear one for the purpose of preventing the eventual sagging. Remember also that breasts will benefit from bra-free time, so it is good to take the bra off whenever you can.

    I doubt that sleeping with a bra on will do anything to your breasts. There are two activities that are most likely to cause breast sagginess: age and nursing.

    Some people claim that wearing bras can promote or increase your chances of breast cancer by restricting the flow of your lymphatic system. A simple "bra breast cancer" search on Google (without the quotes) brought up several articles by doctors supporting this claim. For example:

    http://health2us.com/bra.htm

    I notice that this promotes my idea that women should periodically have their breasts massaged. It feels good to you (when done right) and your man will love it. The doctor has this hopeful observation:

    "There is a remarkable success rate for recovery from fibrocystic breast disease within 10 days to two weeks of going bra-free."

    His recommendation is to not wear a bra more than 12 hours a day, and periodically have your breasts massaged, including the lymph nodes right below your underarms and next to your breasts.

    Take things you hear with a grain of salt. The only question you have that could be possible is that wear a bra while you sleep your boobs wont sag. This is what I have heard when I was younger and I always and still do. And I have very perky beautiful C boobs. And I have noticed most large chested women's boobs sag at least a little. But mine almost look fake, because they are so perfect and perkey.

    Millions of women are affected with breast cancer all around the world. Breast cancer is growing like an epidemic and is predicted that 45,000 patients will die from breast cancer, this year. If you feel a solid lump in your breast, you must visit a specialist for consultation.

    no that is bs! The only true one is that your breasts wont sag as much cause they are getting more support. However if you are wearing a super tight bra better to let the twins breathe a little.

    having children sag your breasts. cancer is caused by carcinogens in the air and food, breast size and shape is dependent mostly on heredity. exercises of chest and arm muscles can help give them a good shape.
