The breast is one of two prominences located on the upper ventral region of the torso of primates. Breast_sentence_1

In females, it serves as the mammary gland, which produces and secretes milk to feed infants. Breast_sentence_2

Both females and males develop breasts from the same embryological tissues. Breast_sentence_3

At puberty, estrogens, in conjunction with growth hormone, cause breast development in female humans and to a much lesser extent in other primates. Breast_sentence_4

Breast development in other primate females generally only occurs with pregnancy. Breast_sentence_5

Subcutaneous fat covers and envelops a network of ducts that converge on the nipple, and these tissues give the breast its size and shape. Breast_sentence_6

At the ends of the ducts are lobules, or clusters of alveoli, where milk is produced and stored in response to hormonal signals. Breast_sentence_7

During pregnancy, the breast responds to a complex interaction of hormones, including estrogens, progesterone, and prolactin, that mediate the completion of its development, namely lobuloalveolar maturation, in preparation of lactation and breastfeeding. Breast_sentence_8

Along with their major function in providing nutrition for infants, female breasts have social and sexual characteristics. Breast_sentence_9

Breasts have been featured in ancient and modern sculpture, art, and photography. Breast_sentence_10

They can figure prominently in the perception of a woman's body and sexual attractiveness. Breast_sentence_11

A number of cultures associate breasts with sexuality and tend to regard bare breasts in public as immodest or indecent. Breast_sentence_12

Breasts, especially the nipples, are an erogenous zone. Breast_sentence_13

Etymology and terminology Breast_section_0

The English word breast derives from the Old English word brēost (breast, bosom) from Proto-Germanic breustam (breast), from the Proto-Indo-European base bhreus– (to swell, to sprout). Breast_sentence_14

The breast spelling conforms to the Scottish and North English dialectal pronunciations. Breast_sentence_15

The Merriam-Webster Dictionary states that "Middle English brest, [comes] from Old English brēost; akin to Old High German brust..., Old Irish brú [belly], [and] Russian bryukho"; the first known usage of the term was before the 12th century. Breast_sentence_16

A large number of colloquial terms for breasts are used in English, ranging from fairly polite terms to vulgar or slang. Breast_sentence_17

Some vulgar slang expressions may be considered to be derogatory or sexist to women. Breast_sentence_18

Anatomy Breast_section_1

In women, the breasts overlie the pectoralis major muscles and usually extend from the level of the second rib to the level of the sixth rib in the front of the human rib cage; thus, the breasts cover much of the chest area and the chest walls. Breast_sentence_19

At the front of the chest, the breast tissue can extend from the clavicle (collarbone) to the middle of the sternum (breastbone). Breast_sentence_20

At the sides of the chest, the breast tissue can extend into the axilla (armpit), and can reach as far to the back as the latissimus dorsi muscle, extending from the lower back to the humerus bone (the bone of the upper arm). Breast_sentence_21

As a mammary gland, the breast is composed of differing layers of tissue, predominantly two types: adipose tissue; and glandular tissue, which affects the lactation functions of the breasts. Breast_sentence_22

Morphologically the breast is tear-shaped. Breast_sentence_23

The superficial tissue layer (superficial fascia) is separated from the skin by 0.5–2.5 cm of subcutaneous fat (adipose tissue). Breast_sentence_24

The suspensory Cooper's ligaments are fibrous-tissue prolongations that radiate from the superficial fascia to the skin envelope. Breast_sentence_25

The female adult breast contains 14–18 irregular lactiferous lobes that converge at the nipple. Breast_sentence_26

The 2.0–4.5 mm milk ducts are immediately surrounded with dense connective tissue that support the glands. Breast_sentence_27

Milk exits the breast through the nipple, which is surrounded by a pigmented area of skin called the areola. Breast_sentence_28

The size of the areola can vary widely among women. Breast_sentence_29

The areola contains modified sweat glands known as Montgomery's glands. Breast_sentence_30

These glands secrete oily fluid that lubricate and protect the nipple during breastfeeding. Breast_sentence_31

Volatile compounds in these secretions may also serve as an olfactory stimulus for the newborn's appetite. Breast_sentence_32

The dimensions and weight of the breast vary widely among women. Breast_sentence_33

A small-to-medium-sized breast weighs 500 grams (1.1 pounds) or less, and a large breast can weigh approximately 750 to 1,000 grams (1.7 to 2.2 pounds) or more. Breast_sentence_34

The tissue composition ratios of the breast also vary among women. Breast_sentence_35

Some women's breasts have varying proportions of glandular tissue than of adipose or connective tissues. Breast_sentence_36

The fat-to-connective-tissue ratio determines the density or firmness of the breast. Breast_sentence_37

During a woman's life, her breasts change size, shape, and weight due to hormonal changes during puberty, the menstrual cycle, pregnancy, breastfeeding, and menopause. Breast_sentence_38

Glandular structure Breast_section_2

The breast is an apocrine gland that produces the milk used to feed an infant. Breast_sentence_39

The nipple of the breast is surrounded by the areola (nipple-areola complex). Breast_sentence_40

The areola has many sebaceous glands, and the skin color varies from pink to dark brown. Breast_sentence_41

The basic units of the breast are the terminal duct lobular units (TDLUs), which produce the fatty breast milk. Breast_sentence_42

They give the breast its offspring-feeding functions as a mammary gland. Breast_sentence_43

They are distributed throughout the body of the breast. Breast_sentence_44

Approximately two-thirds of the lactiferous tissue is within 30 mm of the base of the nipple. Breast_sentence_45

The terminal lactiferous ducts drain the milk from TDLUs into 4–18 lactiferous ducts, which drain to the nipple. Breast_sentence_46

The milk-glands-to-fat ratio is 2:1 in a lactating woman, and 1:1 in a non-lactating woman. Breast_sentence_47

In addition to the milk glands, the breast is also composed of connective tissues (collagen, elastin), white fat, and the suspensory Cooper's ligaments. Breast_sentence_48

Sensation in the breast is provided by the peripheral nervous system innervation by means of the front (anterior) and side (lateral) cutaneous branches of the fourth-, fifth-, and sixth intercostal nerves. Breast_sentence_49

The T-4 nerve (Thoracic spinal nerve 4), which innervates the dermatomic area, supplies sensation to the nipple-areola complex. Breast_sentence_50

Lymphatic drainage Breast_section_3

Approximately 75% of the lymph from the breast travels to the axillary lymph nodes on the same side of the body, whilst 25% of the lymph travels to the parasternal nodes (beside the sternum bone). Breast_sentence_51

A small amount of remaining lymph travels to the other breast and to the abdominal lymph nodes. Breast_sentence_52

The subareolar region has a lymphatic plexus known as the "subareolar plexus of Sappey". Breast_sentence_53

The axillary lymph nodes include the pectoral (chest), subscapular (under the scapula), and humeral (humerus-bone area) lymph-node groups, which drain to the central axillary lymph nodes and to the apical axillary lymph nodes. Breast_sentence_54

The lymphatic drainage of the breasts is especially relevant to oncology because breast cancer is common to the mammary gland, and cancer cells can metastasize (break away) from a tumour and be dispersed to other parts of the body by means of the lymphatic system. Breast_sentence_55

Shape, texture, and support Breast_section_4

The morphologic variations in the size, shape, volume, tissue density, pectoral locale, and spacing of the breasts determine their natural shape, appearance, and position on a woman's chest. Breast_sentence_56

Breast size and other characteristics do not predict the fat-to-milk-gland ratio or the potential for the woman to nurse an infant. Breast_sentence_57

The size and the shape of the breasts are influenced by normal-life hormonal changes (thelarche, menstruation, pregnancy, menopause) and medical conditions (e.g. virginal breast hypertrophy). Breast_sentence_58

The shape of the breasts is naturally determined by the support of the suspensory Cooper's ligaments, the underlying muscle and bone structures of the chest, and by the skin envelope. Breast_sentence_59

The suspensory ligaments sustain the breast from the clavicle (collarbone) and the clavico-pectoral fascia (collarbone and chest) by traversing and encompassing the fat and milk-gland tissues. Breast_sentence_60

The breast is positioned, affixed to, and supported upon the chest wall, while its shape is established and maintained by the skin envelope. Breast_sentence_61

In most women, one breast is slightly larger than the other. Breast_sentence_62

More obvious and persistent asymmetry in breast size occurs in up to 25% of women. Breast_sentence_63

While it has been a common belief that breastfeeding causes breasts to sag, researchers have found that a woman's breasts sag due to four key factors: cigarette smoking, number of pregnancies, gravity, and weight loss or gain. Breast_sentence_64

The base of each breast is attached to the chest by the deep fascia over the pectoralis major muscles. Breast_sentence_65

The space between the breast and the pectoralis major muscle, called retromammary space, gives mobility to the breast. Breast_sentence_66

The chest (thoracic cavity) progressively slopes outwards from the thoracic inlet (atop the breastbone) and above to the lowest ribs that support the breasts. Breast_sentence_67

The inframammary fold, where the lower portion of the breast meets the chest, is an anatomic feature created by the adherence of the breast skin and the underlying connective tissues of the chest; the IMF is the lower-most extent of the anatomic breast. Breast_sentence_68

Normal breast tissue typically has a texture that feels nodular or granular, to an extent that varies considerably from woman to woman. Breast_sentence_69

The study The Evolution of the Human Breast (2001) proposed that the rounded shape of a woman's breast evolved to prevent the sucking infant offspring from suffocating while feeding at the teat; that is, because of the human infant's small jaw, which did not project from the face to reach the nipple, he or she might block the nostrils against the mother's breast if it were of a flatter form (cf. Breast_sentence_70

common chimpanzee). Breast_sentence_71

Theoretically, as the human jaw receded into the face, the woman's body compensated with round breasts. Breast_sentence_72

Development Breast_section_5

Main article: Breast development Breast_sentence_73

The breasts are principally composed of adipose, glandular, and connective tissues. Breast_sentence_74

Because these tissues have hormone receptors, their sizes and volumes fluctuate according to the hormonal changes particular to thelarche (sprouting of breasts), menstruation (egg production), pregnancy (reproduction), lactation (feeding of offspring), and menopause (end of menstruation). Breast_sentence_75

Puberty Breast_section_6

The morphological structure of the human breast is identical in males and females until puberty. Breast_sentence_76

For pubescent girls in thelarche (the breast-development stage), the female sex hormones (principally estrogens) in conjunction with growth hormone promote the sprouting, growth, and development of the breasts. Breast_sentence_77

During this time, the mammary glands grow in size and volume and begin resting on the chest. Breast_sentence_78

These development stages of secondary sex characteristics (breasts, pubic hair, etc.) are illustrated in the five-stage Tanner Scale. Breast_sentence_79

During thelarche the developing breasts are sometimes of unequal size, and usually the left breast is slightly larger. Breast_sentence_80

This condition of asymmetry is transitory and statistically normal in female physical and sexual development. Breast_sentence_81

Medical conditions can cause overdevelopment (e.g., virginal breast hypertrophy, macromastia) or underdevelopment (e.g., tuberous breast deformity, micromastia) in girls and women. Breast_sentence_82

Approximately two years after the onset of puberty (a girl's first menstrual cycle), estrogen and growth hormone stimulate the development and growth of the glandular fat and suspensory tissues that compose the breast. Breast_sentence_83

This continues for approximately four years until the final shape of the breast (size, volume, density) is established at about the age of 21. Breast_sentence_84

Mammoplasia (breast enlargement) in girls begins at puberty, unlike all other primates in which breasts enlarge only during lactation. Breast_sentence_85

Changes during the menstrual cycle Breast_section_7

During the menstrual cycle, the breasts are enlarged by premenstrual water retention and temporary growth. Breast_sentence_86

Pregnancy and breastfeeding Breast_section_8

The breasts reach full maturity only when a woman's first pregnancy occurs. Breast_sentence_87

Changes to the breasts are among the first signs of pregnancy. Breast_sentence_88

The breasts become larger, the nipple-areola complex becomes larger and darker, the Montgomery's glands enlarge, and veins sometimes become more visible. Breast_sentence_89

Breast tenderness during pregnancy is common, especially during the first trimester. Breast_sentence_90

By mid-pregnancy, the breast is physiologically capable of lactation and some women can express colostrum, a form of breast milk. Breast_sentence_91

Pregnancy causes elevated levels of the hormone prolactin, which has a key role in the production of milk. Breast_sentence_92

However, milk production is blocked by the hormones progesterone and estrogen until after delivery, when progesterone and estrogen levels plummet. Breast_sentence_93

Menopause Breast_section_9

At menopause, breast atrophy occurs. Breast_sentence_94

The breasts can decrease in size when the levels of circulating estrogen decline. Breast_sentence_95

The adipose tissue and milk glands also begin to wither. Breast_sentence_96

The breasts can also become enlarged from adverse side effects of combined oral contraceptive pills. Breast_sentence_97

The size of the breasts can also increase and decrease in response to weight fluctuations. Breast_sentence_98

Physical changes to the breasts are often recorded in the stretch marks of the skin envelope; they can serve as historical indicators of the increments and the decrements of the size and volume of a woman's breasts throughout the course of her life. Breast_sentence_99

Breastfeeding Breast_section_10

Main article: Breastfeeding Breast_sentence_100

The primary function of the breasts, as mammary glands, is the nourishing of an infant with breast milk. Breast_sentence_101

Milk is produced in milk-secreting cells in the alveoli. Breast_sentence_102

When the breasts are stimulated by the suckling of her baby, the mother's brain secretes oxytocin. Breast_sentence_103

High levels of oxytocin trigger the contraction of muscle cells surrounding the alveoli, causing milk to flow along the ducts that connect the alveoli to the nipple. Breast_sentence_104

Full-term newborns have an instinct and a need to suck on a nipple, and breastfed babies nurse for both nutrition and for comfort. Breast_sentence_105

Breast milk provides all necessary nutrients for the first six months of life, and then remains an important source of nutrition, alongside solid foods, until at least one or two years of age. Breast_sentence_106

Clinical significance Breast_section_11

Main article: Breast disease Breast_sentence_107

The breast is susceptible to numerous benign and malignant conditions. Breast_sentence_108

The most frequent benign conditions are puerperal mastitis, fibrocystic breast changes and mastalgia. Breast_sentence_109

Lactation unrelated to pregnancy is known as galactorrhea. Breast_sentence_110

It can be caused by certain drugs (such as antipsychotic medications), extreme physical stress, or endocrine disorders. Breast_sentence_111

Lactation in newborns is caused by hormones from the mother that crossed into the baby's bloodstream during pregnancy. Breast_sentence_112

Breast cancer Breast_section_12

Main article: Breast cancer Breast_sentence_113

Breast cancer is the most common cause of cancer death among women and it is one of the leading causes of death among women. Breast_sentence_114

Factors that appear to be implicated in decreasing the risk of breast cancer are regular breast examinations by health care professionals, regular mammograms, self-examination of breasts, healthy diet, and exercise to decrease excess body fat, and breastfeeding. Breast_sentence_115

Male breasts Breast_section_13

Both females and males develop breasts from the same embryological tissues. Breast_sentence_116

Normally, males produce lower levels of estrogens and higher levels of androgens, namely testosterone, which suppress the effects of estrogens in developing excessive breast tissue. Breast_sentence_117

In boys and men, abnormal breast development is manifested as gynecomastia, the consequence of a biochemical imbalance between the normal levels of estrogen and testosterone in the male body. Breast_sentence_118

Around 70% of boys temporarily develop breast tissue during adolescence. Breast_sentence_119

The condition usually resolves by itself within two years. Breast_sentence_120

When male lactation occurs, it is considered a symptom of a disorder of the pituitary gland. Breast_sentence_121

Plastic surgery Breast_section_14

Plastic surgery can be performed to augment or reduce the size of breasts, or reconstruct the breast in cases of deformative disease, such as breast cancer. Breast_sentence_122

Breast augmentation and breast lift (mastopexy) procedures are done only for cosmetic reasons, whereas breast reduction is sometimes medically indicated. Breast_sentence_123

In cases where a woman's breasts are severely asymmetrical, surgery can be performed to either enlarge the smaller breast, reduce the size of the larger breast, or both. Breast_sentence_124

Breast augmentation surgery generally does not interfere with future ability to breastfeed. Breast_sentence_125

Breast reduction surgery more frequently leads to decreased sensation in the nipple-areola complex, and to low milk supply in women who choose to breastfeed. Breast_sentence_126

Implants can interfere with mammography (breast x-rays images). Breast_sentence_127

Society and culture Breast_section_15

General Breast_section_16

In Christian iconography, some works of art depict women with their breasts in their hands or on a platter, signifying that they died as a martyr by having their breasts severed; one example of this is Saint Agatha of Sicily. Breast_sentence_128

Femen is a feminist activist group which uses topless protests as part of their campaigns against sex tourism religious institutions, sexism, and homophobia.Femen activists have been regularly detained by police in response to their protests. Breast_sentence_129

There is a long history of female breasts being used by comedians as a subject for comedy fodder (e.g., British comic Benny Hill's burlesque/slapstick routines). Breast_sentence_130

Art history Breast_section_17

In European pre-historic societies, sculptures of female figures with pronounced or highly exaggerated breasts were common. Breast_sentence_131

A typical example is the so-called Venus of Willendorf, one of many Paleolithic Venus figurines with ample hips and bosom. Breast_sentence_132

Artifacts such as bowls, rock carvings and sacred statues with breasts have been recorded from 15,000 BC up to late antiquity all across Europe, North Africa and the Middle East. Breast_sentence_133

Many female deities representing love and fertility were associated with breasts and breast milk. Breast_sentence_134

Figures of the Phoenician goddess Astarte were represented as pillars studded with breasts. Breast_sentence_135

Isis, an Egyptian goddess who represented, among many other things, ideal motherhood, was often portrayed as suckling pharaohs, thereby confirming their divine status as rulers. Breast_sentence_136

Even certain male deities representing regeneration and fertility were occasionally depicted with breast-like appendices, such as the river god Hapy who was considered to be responsible for the annual overflowing of the Nile. Breast_sentence_137

Female breasts were also prominent in the Minoan civilization in the form of the famous Snake Goddess statuettes. Breast_sentence_138

In Ancient Greece there were several cults worshipping the "Kourotrophos", the suckling mother, represented by goddesses such as Gaia, Hera and Artemis. Breast_sentence_139

The worship of deities symbolized by the female breast in Greece became less common during the first millennium. Breast_sentence_140

The popular adoration of female goddesses decreased significantly during the rise of the Greek city states, a legacy which was passed on to the later Roman Empire. Breast_sentence_141

During the middle of the first millennium BC, Greek culture experienced a gradual change in the perception of female breasts. Breast_sentence_142

Women in art were covered in clothing from the neck down, including female goddesses like Athena, the patron of Athens who represented heroic endeavor. Breast_sentence_143

There were exceptions: Aphrodite, the goddess of love, was more frequently portrayed fully nude, though in postures that were intended to portray shyness or modesty, a portrayal that has been compared to modern pin ups by historian Marilyn Yalom. Breast_sentence_144

Although nude men were depicted standing upright, most depictions of female nudity in Greek art occurred "usually with drapery near at hand and with a forward-bending, self-protecting posture". Breast_sentence_145

A popular legend at the time was of the Amazons, a tribe of fierce female warriors who socialized with men only for procreation and even removed one breast to become better warriors (the idea being that the right breast would interfere with the operation of a bow and arrow). Breast_sentence_146

The legend was a popular motif in art during Greek and Roman antiquity and served as an antithetical cautionary tale. Breast_sentence_147

Body image Breast_section_18

Many women regard their breasts as important to their sexual attractiveness, as a sign of femininity that is important to their sense of self. Breast_sentence_148

A woman with smaller breasts may regard her breasts as less attractive. Breast_sentence_149

Clothing Breast_section_19

See also: Brassiere, Cleavage (breasts), Toplessness, Modesty, Naturism, and Exhibitionism Breast_sentence_150

Because breasts are mostly fatty tissue, their shape can—within limits—be molded by clothing, such as foundation garments. Breast_sentence_151

Bras are commonly worn by about 90% of Western women, and are often worn for support. Breast_sentence_152

The social norm in most Western cultures is to cover breasts in public, though the extent of coverage varies depending on the social context. Breast_sentence_153

Some religions ascribe a special status to the female breast, either in formal teachings or through symbolism. Breast_sentence_154

Islam forbids women from exposing their breasts in public. Breast_sentence_155

Many cultures, including Western cultures in North America, associate breasts with sexuality and tend to regard bare breasts as immodest or indecent. Breast_sentence_156

In some cultures, like the Himba in northern Namibia, bare-breasted women are normal. Breast_sentence_157

In some African cultures, for example, the thigh is regarded as highly sexualised and never exposed in public, but breast exposure is not taboo. Breast_sentence_158

In a few Western countries and regions female toplessness at a beach is acceptable, although it may not be acceptable in the town center. Breast_sentence_159

Social attitudes and laws regarding breastfeeding in public vary widely. Breast_sentence_160

In many countries, breastfeeding in public is common, legally protected, and generally not regarded as an issue. Breast_sentence_161

However, even though the practice may be legal or socially accepted, some mothers may nevertheless be reluctant to expose a breast in public to breastfeed due to actual or potential objections by other people, negative comments, or harassment. Breast_sentence_162

It is estimated that around 63% of mothers across the world have publicly breast-fed. Breast_sentence_163

Bare-breasted women are legal and culturally acceptable at public beaches in Australia and much of Europe. Breast_sentence_164

Filmmaker Lina Esco made a film entitled Free the Nipple, which is about "...laws against female toplessness or restrictions on images of female, but not male, nipples", which Esco states is an example of sexism in society. Breast_sentence_165

Sexual characteristic Breast_section_20

See also: Mammary intercourse, Breast fetishism, and Stimulation of nipples Breast_sentence_166

In some cultures, breasts play a role in human sexual activity. Breast_sentence_167

In Western culture, breasts have a "...hallowed sexual status, arguably more fetishized than either sex’s genitalia". Breast_sentence_168

Breasts and especially the nipples are among the various human erogenous zones. Breast_sentence_169

They are sensitive to the touch as they have many nerve endings; and it is common to press or massage them with hands or orally before or during sexual activity. Breast_sentence_170

During sexual arousal, breast size increases, venous patterns across the breasts become more visible, and nipples harden. Breast_sentence_171

Compared to other primates, human breasts are proportionately large throughout adult females' lives. Breast_sentence_172

Some writers have suggested that they may have evolved as a visual signal of sexual maturity and fertility. Breast_sentence_173

Many people regard bare female breasts to be aesthetically pleasing or erotic, and they can elicit heightened sexual desires in men in many cultures. Breast_sentence_174

In the ancient Indian work the Kama Sutra, light scratching of the breasts with nails and biting with teeth are considered erotic. Breast_sentence_175

Some people show a sexual interest in female breasts distinct from that of the person, which may be regarded as a breast fetish. Breast_sentence_176

A number of Western fashions include clothing which accentuate the breasts, such as the use of push-up bras and decollete (plunging neckline) gowns and blouses which show cleavage. Breast_sentence_177

While U.S. culture prefers breasts that are youthful and upright, some cultures venerate women with drooping breasts, indicating mothering and the wisdom of experience. Breast_sentence_178

Research conducted at the Victoria University of Wellington showed that breasts are often the first thing men look at, and for a longer time than other body parts. Breast_sentence_179

The writers of the study had initially speculated that the reason for this is due to endocrinology with larger breasts indicating higher levels of estrogen and a sign of greater fertility, but the researchers said that "Men may be looking more often at the breasts because they are simply aesthetically pleasing, regardless of the size." Breast_sentence_180

Some women report achieving an orgasm from nipple stimulation, but this is rare. Breast_sentence_181

Research suggests that the orgasms are genital orgasms, and may also be directly linked to "the genital area of the brain". Breast_sentence_182

In these cases, it seems that sensation from the nipples travels to the same part of the brain as sensations from the vagina, clitoris and cervix. Breast_sentence_183

Nipple stimulation may trigger uterine contractions, which then produce a sensation in the genital area of the brain. Breast_sentence_184

Anthropomorphic geography Breast_section_21

Main article: Breast-shaped hill Breast_sentence_185

There are many mountains named after the breast because they resemble it in appearance and so are objects of religious and ancestral veneration as a fertility symbol and of well-being. Breast_sentence_186

In Asia, there was "Breast Mountain", which had a cave where the Buddhist monk Bodhidharma (Da Mo) spent much time in meditation. Breast_sentence_187

Other such breast mountains are Mount Elgon on the Uganda-Kenya border, Beinn Chìochan and the Maiden Paps in Scotland, the "Bundok ng Susong Dalaga" (Maiden's breast mountains) in Talim Island, Philippines, the twin hills known as the Paps of Anu (Dá Chích Anann or "the breasts of Anu"), near Killarney in Ireland, the 2,086 m high Tetica de Bacares or "La Tetica" in the Sierra de Los Filabres, Spain, and Khao Nom Sao in Thailand, Cerro Las Tetas in Puerto Rico and the Breasts of Aphrodite in Mykonos, among many others. Breast_sentence_188

In the United States, the Teton Range is named after the French word for "breast". Breast_sentence_189
