The breast is one of two prominences located on the upper ventral region of the torso among humans and other primates. Both sexes develop breasts from the same embryological tissues. The relative size and development of the breasts is a major secondary sex distinction between males and females.
Plastic surgery is a surgical specialty involving the restoration, reconstruction, or alteration of the human body. It can be divided into two main categories: reconstructive surgery and cosmetic surgery. Reconstructive surgery includes craniofacial surgery, hand surgery, microsurgery, and the treatment of burns. While reconstructive surgery aims to reconstruct a part of the body or improve its functioning, cosmetic surgery aims to improve the appearance of it. A comprehensive definition of plastic surgery has never been established, because it has no distinct anatomical object and thus overlaps with practically all other surgical specialties. An essential feature of plastic surgery is that it involves the treatment of conditions that require or may require tissue relocation skills.
Cooper's ligaments are connective tissue in the breast that help maintain structural integrity. They are named for Astley Cooper, who first described them in 1840. Their anatomy can be revealed using Transmission diffraction tomography.
Breast augmentation and augmentation mammoplasty is a cosmetic surgery technique using breast-implants and fat-graft mammoplasty techniques to increase the size, change the shape, and alter the texture of the breasts. Although in some cases augementation mammoplasty is applied to correct congenital defects of the breasts and the chest wall in other cases it is used purely as a cosmetic surgery, primary breast augmentation changes the aesthetics – of size, shape, and texture – of healthy breasts.
A nursing bra is a specialized brassiere that provides additional support to women who are lactating and permits comfortable breastfeeding without the need to remove the bra. This is accomplished by specially designed bra cups that include flaps which can be opened with one hand to expose the nipple. The flap is usually held closed with a simple clasp or hook.
As a paraphilia, breast fetishism is a sexual interest that focuses exclusively on the female breasts, and is a type of partialism. The term breast fetishism is also used in the non-paraphilic sense, to refer to cultural attention to female breasts and the sexuality they represent.
Cleavage is the narrow depression or hollow between the breasts of a woman. The superior portion of cleavage may be accentuated by clothing such as a low-cut neckline that exposes the division, and often the term is used to describe the low neckline itself, instead of the term décolletage. Joseph Breen, head of the U.S. film industry's Production Code Administration, coined the term in its current meaning when evaluating the 1943 film The Outlaw, starring Jane Russell. The term was explained in Time magazine on August 5, 1946. It is most commonly used in the parlance of Western female fashion to refer to necklines that reveal or emphasize décolletage.
Breast hypertrophy is a rare medical condition of the breast connective tissues in which the breasts become excessively large. The condition is often divided based on the severity into two types, macromastia and gigantomastia. Hypertrophy of the breast tissues may be caused by increased histologic sensitivity to certain hormones such as female sex hormones, prolactin, and growth factors. Breast hypertrophy is a benign progressive enlargement, which can occur in both breasts (bilateral) or only in one breast (unilateral). It was first scientifically described in 1648.
A breast implant is a prosthesis used to change the size, shape, and contour of a person's breast. In reconstructive plastic surgery, breast implants can be placed to restore a natural looking breast following a mastectomy, to correct congenital defects and deformities of the chest wall or, cosmetically, to enlarge the appearance of the breast through breast augmentation surgery.
Ptosis or sagging of the female breast is a natural consequence of aging. The rate at which a woman's breasts drop and the degree of ptosis depends on many factors. The key factors influencing breast ptosis over a woman's lifetime are cigarette smoking, her number of pregnancies, higher body mass index, larger bra cup size, and significant weight change. Post-menopausal women or people with collagen deficiencies may experience increased ptosis due to a loss of skin elasticity. Many women and medical professionals mistakenly believe that breastfeeding increases sagging. It is also commonly believed that the breast itself offers insufficient support and that wearing a bra prevents sagging, which has not been found to be true.
The history of bras is closely tied to the social status of women, the evolution of fashion, and shifting views of the female body over time.
Bra size indicates the size characteristics of a bra. While there is a number of bra sizing systems in use around the world, the bra sizes usually consist of a number, indicating the size of the band around the woman's torso, and one or more letters that indicate the breast cup size. Bra cup sizes were invented in 1932 while band sizes became popular in the 1940s. For convenience, because of the impracticality of determining the size dimensions of each breast, the volume of the bra cup, or cup size, is based on the difference between band length and over-the-bust measurement.
A sports bra is a bra that provides support to the breasts during physical exercise. Sturdier than typical bras, they minimize breast movement and alleviate discomfort. Many women wear sports bras to reduce pain and physical discomfort caused by breast movement during exercise. Some sports bras are designed to be worn as outerwear during exercise such as running. There are also sports bras with extra padding for exercises that involve some kind of trauma to the breasts.
A bra, short for brassiere or brassière, is a form-fitting underwear that is primarily used to support and cover a woman's breasts. A typical bra consists of a chest band that wraps around the torso, supporting two breast cups that are held in place by shoulder straps. A bra usually fastens in the back, using a hook and eye fastener, although bras are available in a large range of styles and sizes, including front-fastening and backless designs. Some bras are designed for specific functions, such as nursing bras to facilitate breastfeeding or sports bras to minimize discomfort during exercise.
A training bra is a lightweight brassiere designed for girls who have begun to develop breasts, at Tanner stage II and III. The training bra is intended to be worn during puberty when the breasts are not yet large enough to fit a standard-sized bra. Training bras often provide minimal or no support, and may serve aesthetic purposes to fulfill cultural norms and local beauty standards.
Female body shape or female figure is the cumulative product of a woman's bone structure along with the distribution of muscle and fat on the body.
An underwire bra is a brassiere that utilizes a thin, semi-circular strip of rigid material fitted inside the brassiere fabric to help lift, separate, shape, and support a woman's breasts. The wire may be made of metal, plastic, or resin. It is sewn into the bra fabric and under each cup, from the center gore to under the wearer's armpit. Many different brassiere designs incorporate an underwire, including shelf bras, demi bras, nursing bras, and bras built into other articles of clothing, such as tank tops, dresses and swimsuits.
In Western society, since the 1960s, there has been a slow but steady trend towards bralessness among a number of women, especially millennials, who have expressed opposition to and are giving up wearing bras. In 2016, Allure magazine fashion director Rachael Wang wrote, "Going braless is as old as feminism, but it seems to be bubbling to the surface more recently as a direct response to Third Wave moments like #freethenipple hashtag campaign, increased trans-visibility like Caitlyn Jenner's Vanity Fair cover ... and Lena Dunham's show Girls."
No Bra Day is an annual observance on October 13 on which women are encouraged to go braless as a means to encourage breast cancer awareness. No Bra Day was initially observed on July 9, 2011, but within three years it had moved to the 13th day of the National Breast Cancer Awareness Month, October. Users on social media are encouraged to post using the hashtag #nobraday to promote awareness of breast cancer symptoms and to encourage gender equality. Some users on social media sites also encourage women to post pictures of themselves not wearing a bra. Some women embrace No Bra Day as a political statement while others prefer the comfort of discarding what they view as a restrictive, uncomfortable garment.
