The breast is one of two prominences located on the upper ventral region of a primate's torso. Both females and males develop breasts from the same embryological tissues.
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.
Reduction mammoplasty is the plastic surgery procedure for reducing the size of large breasts. In a breast reduction surgery for re-establishing a functional bust that is proportionate to the woman's body, the critical corrective consideration is the tissue viability of the nipple–areola complex (NAC), to ensure the functional sensitivity and lactational capability of the breasts. The indications for breast reduction surgery are three-fold – physical, aesthetic, and psychological – the restoration of the bust, of the woman's self-image, and of her mental health.
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.
Pasties are patches that cover a person's nipples and areolae, typically self-adhesive or affixed with adhesive. They originated as part of burlesque shows, allowing dancers to perform fully topless without exposing the nipples in order to provide a commercial form of bare-breasted entertainment. Pasties are also, at times, used while sunbathing, worn by strippers and showgirls, or as a form of protest during women's rights events such as Go Topless Day. In some cases this is to avoid potential prosecution under indecency laws.
An inverted nipple is a condition where the nipple, instead of pointing outward, is retracted into the breast. In some cases, the nipple will be temporarily protruded if stimulated. Both women and men can have inverted nipples.
The intermammary cleft or intermammary sulcus or sulcus intermammarius is a surface feature of males and females that marks the division of the two breasts with the sternum (breastbone) in the middle. The International Federation of Associations of Anatomists (IFAA) uses the terms "sulcus intermammarius" or "intermammary cleft" when referring to the area between the breasts.
Mastopexy is the plastic surgery mammoplasty procedure for raising sagging breasts upon the chest of the woman, by changing and modifying the size, contour, and elevation of the breasts. In a breast-lift surgery to re-establish an aesthetically proportionate bust for the woman, the critical corrective consideration is the tissue viability of the nipple-areola complex (NAC), to ensure the functional sensitivity of the breasts for lactation and breast-feeding.
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.
Male bra – also known as a compression bra, compression vest, or gynecomastia vest – refers to brassieres that are worn by men. Men sometimes develop breasts and the estimates of those with the condition are presented as a range "because the definition of gynecomastia varies and the method of surveying varies." Although there are options for treating gynecomastia, some elect surgery to reduce their breasts or wear a male bra. Male bras typically flatten rather than lift.
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 bra, short for brassiere or brassière, is a form-fitting undergarment 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.
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.
Tuberous breasts are a result of a congenital abnormality of the breasts which can occur in both men and women, one breast or both. During puberty breast development is stymied and the breasts fail to develop normally and fully. The exact cause of this is as yet unclear; however, a study in 2011 of the cells in the breasts of both males and females with tubular breasts suggested a genetic link in a disorder of collagen deposition. The condition is thought to affect one to five per cent of breast augmentation patients; however, the proportion of the general population affected is unknown as surgery is not always sought.
Wearing underwear as outerwear is a fashion trend popularized by celebrities, sports and media. It began as a practical and comfortable variation of clothing, such as the T-shirt and the sleeveless shirt, but would later become fashion statements that would be controversial and accused of being provocative. 21st century versions include the display of thongs and bras in women's clothing, and the display of underpants under low-slung pants in men. Wearing underwear as outerwear has historical antecedents in the display of undergarments in the sixteenth and seventeenth centuries.
Maternal physiological changes in pregnancy are the adaptations that take place during pregnancy that enable the accommodation of the developing embryo and fetus. These are normal physiological adaptations that cause changes in behavior, the functioning of the heart, blood vessels, and blood, metabolism including increases in blood sugar levels, kidney function, posture, and breathing. During pregnancy numerous hormones and proteins are secreted that also have a broad range of effects.
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.
